Getting a convex edge with the CPM-15V blade of the Houlahoula Para3 Lightweight.

3 Comments

I have enjoyed the Para3 in CPM15V for a week now and after the first pictures, one of my friend Alexandre wrote to me “Looking forward for a convex edge”.
And I have answered to him that I was not in a hurry to do it on this little wonder of modern cutlery. The steel seemed so hard !
But guess what ? What’s bred in the bone will come out in the flesh.
After a week of frustration trying to get any good (spectacular) result on leather and white ceramic….

Some gaffer is on the blade to protect it from any scratches.
My goal is just to “de-shoulder” the edge, to round it for a better leather stropping experience.

It is not rocket science and I’m clumsy and impatient.
So I’m not helped by natural tendencies.
As you can notice the edge near the guard will have less attention.
My friend JD is able to go even but I’m not to his level in making beautiful edges.

But as you can notice it is getting better.
I use a Double Stuff 2 from Spyderco. Mine is old and the glue between the ceramic slate has gone. The diamond slate is not as efficient as some decades ago but it should bite into CPM15V despite its humungous pourcentage of vanadium.

“Since CPM 15V has a high volume (23%) of vanadium carbides (87 HRC) which are harder than the ceramic alumina abrasives. (79 HRC)

That means 23% of the overall microstructure is being pulverized, burnished and adhesively worn to shape rather than cut at the apex.

Over the years I’ve observed a pattern in some folks complaining that these types of steels cannot get very sharp yet the same folks seemingly would refuse to use the abrasive that will cut the remaining 23% of that microstructure cleanly.

I do think that would be fascinating to do a controlled test and look at the differences between the starting sharpness and how that sharpness dies off with cut testing and then compare the loss of sharpness between the two with the same amount of cuts.

I’ve certainly seen this behavior in my personal experience, however, I’ve not documented and shared data publicly.

I’ve mentioned many times that my current favorites for sharpening are the bonded super abrasives rather than the electroplated abrasives. However, there is a cost difference, but in my experience it certainly pays for itself and has better performance.“
Shawn Houston on the Spyderco Forums

First look at the result.

Humm it needs to go one more round.

Ah, I am starting to enjoy the result and how the steel takes the light on the belly of the blade.

Now time to put some white compound polish on the leather.

Again I’m not focusing on getting it sharper it but just to polish the edge and remove any scratches. I want a better geometry like I use to have on the Para3 in M390.

CPM15V does not like to give away its particules.
When I have been able to get mirror edges on D2, 52100 or SPY27 I’m not able to get it on 15V. I need certainly to upgrade my equipement and my game for that.
I will polish it on Jade stone and post better results in the coming weeks.
So far I’m happy with the result. More to come later as 15V is not as easy as I thought to work on (JD adviced me “I think diamond past would help with the stropping. Diamonds or cbn can cut the vanadium carbides, of with this steel has a lot”. Not impossible, especially with diamonds but easy. Maxamet on the other side has proven to be much easier to restore even after catastrophic damages.
But I’m very happy with that Para3 which could be the HoulaHoula (*) of folding knives.


(*) Houlahoula are little birds with big balls and when they land they sing “Houla ! Houla !


On the Spyderco Forums Shawn Houston was kind enough to give some advice about how to get a mirror edge on CPM 15V:

“I recommend skipping the White Ceramic and Jade.
23% of the matrix in the 15V is harder than those abrasives.
A bonded diamond/cBN stone should help with the desired finish.

You deburr the best you can with light alternating passes on the stone. From here, the edge should be sharp enough to cut paper cleanly before moving on. Afterwards, go to a leather strop loaded with 1um Gunny Juice and use alternating edge trailing passes.

This is a good benchmark; keeps the “bite” at the edge without smoothing out the slicing effect. It also helps keep the “grab” at the edge for draw cuts but still keen enough for push cuts.

There’s different kinds of stones. They’re not all created equal.
You can take a diamond stone with the same abrasive and the same grit and it will leave a different surface roughness depending on the construction of the stone.
Yes, there are three major types of bonded stone.

Metallic, resin and vitrified.

There’s even some that are hybrids. However, these are not the same as electroplated diamond abrasives.The work more like regular water stones with better surface finishes.

“Diamond or CBN are the way. You can put a functional edge on 15V with ceramics, but if you’re wanting the real performance 15V has to offer, you need to sharpen with abrasives that will cut the carbides in the steel.”
Wandering_About on the Forums has sum it up.

Shawn Houston was also kind enough to share an AI summary of Instagram Reviews.

“Based on the latest set of reviews, BBB CPM 15V steel demonstrates exceptional performance and user satisfaction.

Performance:
* Excellent edge retention: Maintains a sharp edge for extended periods, even with demanding use (e.g., cutting blackberry roots, heavy use).
* High edge stability: Resistant to chipping and rolling, even with hard use.
* Versatile: Performs well with different edge angles and finishes (from toothy to mirror).

Comparisons:
* Compared to K390, Maxamet, S90V: Sharpening is considered easier than K390 and Maxamet.
* Compared to M4: Sharpening is considered comparable in difficulty to M4.

Key findings:
* Sharpening Ease: Despite its high hardness and carbide content, 15V is surprisingly easy to sharpen. Users report successful sharpening experiences on a variety of tools, from diamond stones and CBN plates to simpler systems. Burr removal is consistently described as effortless.
* Edge Retention and Stability: 15V exhibits excellent edge retention, maintaining sharpness through demanding tasks and heavy use. It also demonstrates high edge stability, showing resistance to chipping and rolling.
* Versatility: The steel is versatile, capable of achieving both aggressive, toothy edges and refined, smooth edges.
* User Enthusiasm: Many users express high levels of satisfaction with 15V, with some even considering it their favorite steel.
Overall:
BBB CPM 15V appears to be a top-tier steel that effectively balances exceptional performance with user-friendly sharpening characteristics. Its combination of edge retention, stability, and ease of use makes it a strong contender for demanding tasks and a highly recommended choice for knife enthusiasts.”

Spyderco Para 3 Lightweight 15V Sprint Run – C223PBN15V – First glimpse at the Lil’Brown Bear !

3 Comments

Jumping on the Para® 3 Lightweight Brown CPM® 15V® Sprint Run® wagon was an easy choice after a month of watching our American friends review this new CPM-15V batch.

Following the Manix 2 release two years ago, showcased in the Reveal 11, and a Paramilitary Brown version, here is the chance to test this remarkable steel on a lightweight platform: the Para 3 in brown FRN.


For record CPM 15V is “Boasting almost a 15 percent vanadium content, this remarkable material offers the highest wear resistance of any cold work tool steel available today. The full-flat-ground, satin-finished blade of this knife is further enhanced by a specialized heat-treating protocol developed by acclaimed custom knifemaker Shawn Houston. The result is a blade that offers extreme sharpness and unparalleled edge retention.”

Shawn Houston is known as Big Brown Bear on youtube and his skills in metallurgy and knifemaking as drawn the attention of the Glesser’s family.

In 2018, he has written on the Spyderco Forums that request:
“Sal, Can we get CPM 15v?
“I like this steel. It’s easier to work with then Maxamet and Rex121.
Takes a killer edge and seems to be more stable then s110v.“

Larrin Thomas even answered:
“You guys are crazy. But with Spyderco anything is possible.”

And in 2022 a first Spyderco knife designed by Shawn Houston in 15V with his own heat treat protocol was proposed. Eric’s Manix 2.

“The CPM 15V Sprint run was supposed to be a surprise treat.
Eric wanted to share the CPM 15V with the custom heat treatment I worked on for my folder design.
His idea was to use a standard model so people can get their hands on the steel. Which I thought was really, REALLY cool of him to do that.
Working with Crucible and Niagara Specialty Metal we were able to select a specific melt of the CPM 15V that would respond best to this specially developed custom heat treatment. 
So, Eric and Sal really went all the way on this, no other production knife company on the planet would do something like this. Eric and Sal are one of a kind. 
You guys need to understand this is very unique having actual knife/steel/sharpening/edge people running a knife company that can cater to enthusiasts. 
Originally, I was given options for different handle scales for the Manix but the most important priority was to get the CPM 15V Manix out as soon as possible so it didn’t make any sense to use exotic scale materials.
G10 is a great material to work with and brown g10 was selected because “Big Brown Bear” aka Triplebhandmade. (Me)
I am aware as many others that brown g10 is not unique to this model.
But the color of the handle scales and the handle scale material are irrelevant to edge performance and the most important priority was getting this out to you guys as soon as possible.
Looks like the price is great too, if we used carbon fiber etc cost would have been higher.
So, I hope you guys can respect that.
The folder collaboration design was being pushed back due to production capacity being completely full at Golden.
Please understand that I’ve been very persistent at wanting the knife made in Golden come **** or high water; I would wait until the stars burned out.
Spyderco has been very busy increasing the size of their golden factory to meet the insane demand of the current knife industry after the global pandemic.
Keep in mind, when a new product comes through the factory, they have to train the staff on how to make them, and what the best procedures are for creating that specific model in high volume with maximum efficiency. So, there is hidden effort when new designs come through at Spyderco.
Folks need to remember if we want this folder made in Golden (my favorite factory) we have to be patient. 
My dream is to have a Golden folder we can all experience together.

I’ve gotten a chance to meet the people from the Golden factory I must say I’m even more excited about the idea of it being made in Golden. I’ve talked to the people that do grinding and heat treatment and there’s just something special about being able to talk to the folks that make your collaboration knife design.
So, I keep pretty quiet about the folder because I don’t feel it’s necessary to see get people excited about something that doesn’t have a clearly set date of exactly when it can be expected and I don’t want to put any undue pressure on Spyderco because they’ve been working very very hard over the past couple years to get things that sometimes people take for granted and expect to magically appear on the shelves to buy.
While I haven’t been posting in this thread everyday, I really appreciate you guys making sure to let Spyderco know this is something you want.
So, thanks for always updating this thread and talking about it on social media.I really think you guys will like this knife and I can’t wait to get one in my pocket one day.

-Shawn“

Now this is new batch including Microjimbo, Yojumbo, Yojimbo2, Native, Military 2, Para3 G10 and Para3 Lightweight.

Like all its brothers and sisters it boast the BBB logo proving that the blade has followed Shawn Houston heat treatment.

In his excellent vidéo Shawn share his first impressions and also check the hardness of his Para3 and the result is 65.4 HRC ! Impressive !

Framed from his video: he performed five separate hardness tests just to be sure. It’s well known that Shawn Houston’s special heat treatment — refined over years and tested by renowned professionals — brings out the quintessence of CPM-15V, elevating its performance to exceptional levels.

“Well, most heat treatment protocols are for tooling, like the ones in datasheets — not really optimized for things like edge stability.”
— Shawn Houston, on his own heat treatment

In practical tests, Pete from the Cedric and Ada Gear and Outdoors was able to cut through a rope 2,000 times without compromising the edge.

The action on my new Para 3 is perfectly smooth. I notice a little lock sticking but this is not an issue in my book.


And smooth enough that nothing unscrews on it — the blade closes like glass, effortlessly and precisely.

My Para 3 arrived perfectly centered, but with some burrs on the scales.
(A burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process.)

You can feel these tiny imperfections under your finger along the FRN edges.

I have “deburr” it with some diamonds rod. Nothing fancy but now the handle is fine. I don’t remember having that issue on my previous Para 3 review.

The edge is even.

I don’t see myself working on a convex edge on this one. Not for the moment.

The sharpness is high and that blade is a hair popping sharp razor right out of the box.

I have already cut my self with its very pointy point. My Para 3 is baptized !

Now it is truly mind.

It is said that CPM-15V loves leather for a crispy edge.
(S90V or M398 for example don’t care about stropping…)

I’m curious how its 68 grams will compete with my Maxamet Para 3 G10 (98 grams) — sturdy yet smooth as velvet.

According to Spyderco:

“The term ‘lightweight,’ or the use of injection-molded handle components on a Spyderco folder, isn’t just about how the knife tips the scale. It’s about taking full advantage of the remarkable properties of FRN and FRCP, as well as our decades of experience as an industry leader in their use.”

So yes, this is a “light” saber.

The edge appears ground thinner than on the notoriously brittle Maxamet blade. Both blades receive special attention: the spine is smooth under the thumb, and the edges are expertly bevelled.

The chance to have such a steel on a lightweight folder would make it a great hunting knife like the Michael Walker ZDP-189 was in his days.
The game’s fur is very abbrasive. CPM-15V could be even stronger than ZDP189 on the joints, more permissive.

Ericasedc has made a video about that:

She seems really happy with her Para 3 since she has received it. You can see all the videos she has made on her channel about the Para 3 15V.

Anyway, going in the woods equipped with a Tenacious CPM M4 and a Para 3 in 15V would be a great combo nowadays.


Now that I can carry the mighty CPM-15V steel in my pocket, I’m eager to test its performance over the long run. Stay tuned for updates on this page or in another chapter.

Having a featherweight folder equipped with such a formidable blade and steel is uncanny — it packs remarkable power in a pocket-sized package. I still remember fitting the Maxamet blade on my red FRN Para 3 just to experience that sensation of a powerful engine on a lightweight platform.

This Para 3 Sprint Run is already a triumph, offering the chance to experience a remarkable steel crafted by passionate knifeaholics.

As mentioned, I have no intention of convexing the edge for now — I’m trusting Shawn’s expertise. Unlike AEB-L, which can be thinned while remaining strong, CPM-15V is packed with carbides, so I’ll stick with the angle specified by Spyderco and Shawn, which is already thinner than Maxamet.

But now, the real fun begins: testing!
Spoiler: the combination of geometry and steel makes it an excellent whittler — the blade cuts deep, and the wood feels incredibly smooth under the cut.



Final word of this review are from Shawn Houston who was quoting and answering to Todd from Scienceofsharp.com about 15V (as Todd’s goal is to increase our understanding of the role of carbides in cutting performance and how different sharpening techniques “interact” with the carbide):
““tremendous pleasure in using an extremely sharp knife or tool (and satisfaction when you have sharpened it yourself). Even though it is often a fleeting experience”
That’s the “idée fixe” of it all.
The little smile and feeling of elation when the edge lasers through material with zero effort.
The stones, geometries, steels, heat treatments and the techniques.
Chasing those fleeting moments of joy with high performance and riding the line between madness and clarity in trying to understand at the most intricate levels how it all really works.
An insatiable quest.“

“The Edge is a Ghost. Always changing. Dying (dulling) being reborn (sharpened) split personality (angles and geometry changing).

Think of the edge as gas in a vehicle. It runs out of gas and you put in more gas. We provide the format, materials, design for use, variety to avoid boredom and create interest, but the edge is your creation. The result of your understanding, education, experience and practice.”

Sal

“CPM 15V is a very difficult steel to manufacturer, so it may not always be available in the future.
Crucible Industries LLC went to great lengths to produce the steel, it puts a great amount of wear and tear on the ceramic refractory designed to hold the super heated liquid steel during melting. This is necessary to dissolve the vanadium carbides to the very fine sizes that we see in the finished product.
It’s quite a marvel that’s not often appreciated.
15V is basically the commercial limit for how much carbon and vandium they can get in a steel for production sizes batches.
The benefits of this to the end user combined with excellent heat treatment is a enjoyable, lasting cutting experience that also touches up at the edge nicely with proper abrasives and sharpening experience.”

Spyderco Tenacious C122GBNM4PS – CPM-M4 with Serrations – Pure Workhorse

6 Comments

I’ve been tenacious — truly tenacious — in resisting the C122 Tenacious, even though I’d had my eye on that folder since 2008. After 17 years of flirtation, I finally ordered one. Why the delay? Its main weakness was always the less-than-stellar steel compared to the high-end knives I already owned.

Now, the CPM-M4 version is here to quench that long-standing thirst.

I don’t have much memory of a CPM-M4 serrated edge, except with another Eric Glesser design: the Dodo Exclusivefrom Blade HQ (C80GM4S). The Dodo was a real wood slasher — its S-shaped blade trimmed vines deeper and faster than almost any other, and the comfortable handle was perfect for power cuts.

Opportunities to play with a serrated CPM-M4 edge have been rare — until now. Here it is.

Back in 2008, when the Tenacious have been released it was a success.

Eric Glesser’s design was appealing to many for a simple reason: it was a well-thought-out, tough workhorse knifeavailable for around €30 (or less). A true blue-collar tool — built to be used and abused, like a modern-day Buck 110 for the pocket.


The best thing about the Tenacious was that it offered a thick, sturdy, well-built liner lock at a time when liner locks were falling out of fashion. Easy to display, easy to use, this no-choil, long-edge, compact working folder from Eric Glesser was a hit — and one of the best ways to catch the Spydervirus.


Now there is a FRN version in CPM S35VN. But it is as heavy as the G10 version and I’m not really a fan of FRN… Even if I absolutely love the FRN scales of my Serrated Chaparral.

I remember Bushcrafters being the first to sing the praises of the Tenacious. An example:

“I’ve thrown it, dropped it, batoned wood as thick as my wrist, chipped the edge multiple times (didn’t think 8cr13mov could chip, thought it was too soft but was wrong), I’ve left in outside ONCE in the rain overnight because I forgot I placed it on my front porch the previous day, I have spine whacked it (just don’t, I most likely have an impulse problem… lol … same problem that causes me to buy a lot of knives) I’ve dug holes, stabbed the ground to cut weed roots out, and much much more...

I think by now you get the point. I treated the tenacious as if I got it for free and had 1000 more to replace it if something happened. I treated this knife as if I hated it.

The result? 4 years later, the Tenacious opens smoother than it ever has, not a speck of rust since I purchased it, I have oiled the blade a couple times but I can guarantee it was less than 20 times total in the last 4 years, lockup is a bit less solid, BARELY any blade play from side to side, even less blade play from front to back, g10 scales look smoothed over and scarred, but to be honest there is still plenty of traction.
All in all, this knife is much more than what most of you need from a folder.”

My Persistence experience was excellent as described in my 2012 review (green words lead to link) but eventually I was disappointed with their steel. 8Cr13MoV can get sharp but lose sharpness much too fast for my uses. It was frustratring. I still got 8Cr13MoV knives like the Clipitool which is a great oyster knife. 8Cr13MoV is tough for a stainless steel, no surprise it was chosen for the Tenacious line.

The Tenacious is a sturdy well made liner lock folder with a super tool steel blade.

“This remarkable expression of the Tenacious® elevates this best-selling design to all-new heights with a blade crafted from American-made CPM M4 tool steel. Produced by the particle metallurgy process, CPM M4’s sophisticated alloy composition, high vanadium content, and extremely fine grain structure give it exceptional wear resistance and toughness-properties that translate to outstanding edge retention and impact resistance in knife blades. This knife’s full-flat-ground blade is available in both PlainEdge™ and CombinationEdge™ formats and is housed in a handle featuring brown peel-ply-textured G-10 scales.“

I have written many reviews about that fabulous alloy CPM-M4 it has never disappointed me and since I have sold my CPM-M4 Military and kept my Yojimbo 2 and Mantra 2 (reviewed and sharpened by JD) and use them hard, I know it is reliable and get a nice patina.

A lil’oil will prevent rust. CPM M4 is not 52100 and the patina will come slowly after cutting some lemons…
“CPM M4 has good edge holding, sharpening ease, toughness, strength, and is not a rust monster…” to quote Rangodash.

Now a blade is 1/3 steel, 1/3 Heat Treatment and 1/3 geometry.

The Coke butt bottle pushing cutting test has been done with the factory edge right out of the box. It is thin behind the edge.  It’s a good blade thickness for more nuanced jobs, but there is added strength from the thicker spine. 

The knife sliced right in the middle were the materiel is thicker.
This is just outstanding !

There are a great geometry and a thin edge on that tough CPM-M4 blade. The result is a sturdy matter separator.

It is not an exploit to cut into some tin can but the same “shallow”, “non snaggy” kind of serrations as the Chaparral made it easy.

Again, this is a “performance oriented” knife. The blade is not too thick like some “tactical” toys. It is made to perform not to show off.

“For notching, serrated edges work great. Feathersticking, maybe, maybe not. Serrated edges are ground on the show side, so they actually work better when used left-handed for cuts like that. I carry a serrated K390 Police4 all the time for rough work. It goes through little volunteer elm trees like a chainsaw. A SharpMaker makes it a breeze to maintain the edge.” to quote Yablanowitz.

The liner lock is thick in the same spirit of Gayle Bradley’s folders.
The knife opens with a loud KLAK! — no blade play in any direction. The detent is strong but slightly “elastic,” meaning the blade moves a little before the release/tipping point engages. This makes it very secure, with no risk of accidental opening. I’ve noticed the same elasticity on the titanium version of the Tenacious. It’s important to note: this is not a weak detent — the blade won’t open without a deliberate, serious force.

Using the knife in Spyderdrop mode, a flick of the wrist catches the blade in the Spyderhole with no issue. Closing remains perfectly secure. There’s a tiny squeak out of the box, but a few drops of nano oil should mute it. The action isn’t buttery smooth like a compression lock on ball bearings, but after a bit of breaking-in and running-in, it will be wonderful.

The solid clip is delivered mounted in Tip Down carry, which suits well this knife for the Spyderco Drop featured on the Military 1 which got the same kind of “around the pivot” clip.

I have no intention of using tip-up carry or a deep-carry clip. This knife is a tool, meant for easy access rather than a stealthy edge. The Tenacious is always noticeable in the pocket, but that sturdy clip guarantees quick availability — reminding me of Massad Ayoob’s teachings.

Spyderdropping is an extremely fast way to get the blade into action — faster than many switchblades. Sal Glesser was already demonstrating this skill almost 30 years ago: grab the knife by the Spyderhole and SCHLAK! — it’s open and ready to cut.

The Tenacious features full steel liners, unlike the nested liners on the Military line. There are no backspacers, making it easy to clean under running water. At 120 grams, it’s not a lightweight folder — I appreciate a bit of heft on a working tool. (For reference, the new titanium version is 93 grams.)

Notice how perfectly centered the blade is right out of the box. The quality control on this “made in China” folder is impressively high.

(Sal’s Titanium Catbird (only 200 were made) next to Eric’s Tenacious.)

Eric and Sal have taken their time with the Byrd Line and their budget line to get the best from a family of makers in China. The Glessers have moved slowly but steadily, developing a trustworthy and excellent relationship with the knifemakers there.


To quote JustinRose40 on the forums in 2011:
“Yes, every time I show someone my Tenacious I have to say “well it’s made in China but it’s not a China Knife, it’s still a Spyderco”. To which they usually say something like, “yeah I could tell that as soon as you handed to me”.

Since 2011, China has made huge leaps in knife manufacturing quality, and this steady improvement is clearly noticeable in the “new” rendition of the venerable Tenacious.

On Eric’s designs, there’s sometimes no choil, but you can notice a clever feature: a “proto-flipper” that acts as a quillon or guard to protect your fingers in case the lock ever failed.

Since 2008, I haven’t heard of any critical lock failures on the Tenacious or the larger Resilience. The Tenacious has earned its legendary status for a reason.

Another Eric design with an excellent blade-to-handle ratio is the Mantra 2, which uses a flipper. (I’m not a fan of that little opening hole — dirt always collects there!) Still, it’s a great design. The Mantra 1, with an opening hole, feels like the Taichung-made “uncle” of the M4 Tenacious.

The peel-ply-textured G10 scales don’t need sanding; they’re well balanced and won’t shred pockets. The brown color makes it feel less threatening, in my book.

Let’s put it to use while the satin blade is still silver.

The knife bites into wood like no tomorrow. The serrated CPM-M4 edge is a joy to use — it goes deep and steady, putting a smile on my face every time.

Blast from the past: the last combo-edge/semi-serrated knife I used was over 20 years ago — a Pre-Production D2 AFCK. As you can see, it’s been heavily used, and its geometry, steel, and blade-to-handle ratio aren’t nearly as refined as the Tenacious.

That macro shot shows the very smooth way to go from chisel ground serrations to plain edge.

“Serrated edges aren’t for everyone, and you may not like them, but you’ve got to get at least one just to try! Keep it around for nasty work, wet abrasive rope, zip-ties, yardwork, or playtime like in the pool, or at the lake or beach. Not to mention fishing duties.” to quote Benben.

The difference in cutting efficiency between a saber grind and a full flat grind is obvious. I don’t need to tiptoe around it — the advantage is clear.

Now let’s compare the Tenacious with various folders and fixed blades.

The Tenacious got a better blade/handle ratio than the Paramilitary 2 and a longer blade for a shorter handle. This is one key of the success of that design.

Almost the same length as the Chief.

No choil on the Wolfspyder too.

Since I play with Bushcraft here a nice combo to go in the wood. The Proficient is a masterpiece.

And with the ultra solide Boker in Magnacut. The 8,6 centimeter long blade of the Tenacious is generous edge wise.

Of course, I’ll strop that partially serrated blade on leather — no fear at all. I have my method for serrations, using the corner of the leather pad.

Maintaining the combo edge won’t be an issue; I’ll keep it sharp with cornered ceramic and jade stones.

So what do you get for €139 — the price I paid at the Coutellerie Champenoise? I’m really happy with my purchase. I plan to use the Tenacious a lot and on anything, simply for the pleasure of testing it on various materials. This knife isn’t afraid of plastic, wood, food, bones, cardboard, or aluminum.

This CPM-M4 version is set to show the full potential of one of the beefier EDC knives, especially with its serrated half-edge carved from super tool steel. Over 17 years, the Tenacious has proven it can withstand a lot of abuse.

  The CPM-M4 Tenacious is not only a workhorse but a warhorse, like the pictured Adamas. I can easily imagine any soldier being glad to have such a reliable knife at this budget.

It’s slightly larger than small pocket knives, but smaller than the oversized ones some carry just to show off. The Tenacious would make an excellent day-hiking knife — a folder ready for the great outdoors. I’d take it on a trip to Africa or on a photo safari in the natural parks of Tuscany.

(this will often dull the blade’s edge with a little shining spot. Not here… Thanks to the serrations again ! )

This CPM-M4 Tenacious is sold at roughly double the price of the standard version, but in my opinion, it’s a rare chance to have this alloy on that knife. CPM-M4 pushes the boundaries of reliability and is a real pleasure to keep razor-sharp.

CPM-M4 will not chip and stays sharp for long. It’s a steel that has been used in cutting competitions. While Tuff Glideand various oils can keep it spotless, I prefer the protection of a gentle natural patina.

For twice the price of the vanilla Tenacious, this upgraded version delivers another level of performance in terms of toughness and edge retention.

“Old school cool with the Walker lock and satin finish. Well done Eric Glesser!” to quote Clay H on the Forums.
My brown Tenacious looks gorgeous in its “beautility”, practically begging to be used across all terrains — sand, rain, or more. All in all, this beater is a beefed-up workhorse, built to be used hard and carried proudly.

Spyderco -C94GCBL- UK PENKNIFE™ COBALT BLUE G-10 CPM® SPY27® – The Blue Djinn Who Loved Leather.

Leave a comment

This is not the first UKPK I have reviewed in this blog. I was a very early adopter of this Sal Glesser’s approach of the modern slipjoint all made in Golden Colorado.
Some of my favorite are the Salt Versions in FRN: the Green LC200N and the Yellow CPM Magnacut. I even think, the serrated version of the Magnacut version could be an amazing legal travelling knife.

But they are FRN versions. I like FRN but I do love G10. Better, I’m a sucker for sanded G-10. Hence my love for the Heinnie Urban and its non-slip peel-ply texture.
At first glance the satin-finished CPM SPY27 blade and signature cobalt blue peel-plytextured G-10 handle scales are juste gorgeous. Here are the full specs on Spyderco’s pages.

Like the Heinnie the skip joint got a strong mechanism. It is really a pleasure to feel this resistance which was totally absent from the very first drop point UKPK a decade ago. (Picture from Mr Blonde, Spydercollector site)

So far, I cannot imagine my self opening it with a flick like I was able to do on the LC200N FRN version. The Spring here on this G10 version is much stronger.

Let’s do some size comparaison. The UKPK is one of the long Slipit in Spyderco’s collection. It is almost a slipjoint Caly, even longer than a Chaparral. So you really don’t feel “underknifed” when you carry it in your pocket as your only EDC. It is also really handy and practical as a kitchen knife. The best thing is that this design keeps its blade length legal in most countries.

For cooking I often use a Native Chief.

The long leaf shaped blade is a must in the kitchen almost idea. It is pointy enough and its is enough for vegetables. Most of the works done in the kitchen like peeling potatoes, cutting oinions, you name it, was always done with a short full flat ground knife like a “Nogent Couteau d’Office”.

Something about the G-10 version is the spring/back spacer closing the handle of the knife when the FRN got an open handle easier to rinse.
But it is much more gorgeous and with a stronger spring for sure !

It also gives a little more heft to the knife. 48 grams for the FRN and 63 grams for the G10 version -> 31,25% heavier to be precise, almost a third ! But I do really love my heavy butt knives since my Schrade Sharpfinger.

Now this is my first CPM-SPY27 knife. Spy27 is a alloy recipe created in house with Crucible exclusively for Spyderco. It is a CPM ! So this is a premium super steel compared to VG10 or N690… In short it is a American Powder Metallurgy version of the Japanese VG10.

In Sal Glesser words:
“We offer many steels for several reasons;
1) We are Steel Junky’s (even Edge Junky’s) and we like to experience the different flavors and we try to do that.
2) We believe that many of our customers are also Steel Junky’s (even Edge Junky’s) and they too get to experience and play with and “taste” as you say, the many options.

I wanted a USA made “tweaked” version of Gingami 1 by Hitachi and after some effort with Carpenter, we have a powdered USA made steel called CTS-BD1N Which is a refinement of Gingami 1. I wanted a USA made “tweaked” version of Takefu’s VG-10 and now we have a powdered “tweaked” SPY27.“

There is a very nice analysis in Knifesteelnerd and discussion here: https://forum.spyderco.com/viewtopic.php?t=94182

“However, it should be noted that the SPY 27 Larrin used for testing was not heat treated by Spyderco. Some minor differences between Larrin’s heat treatment and Spyderco’s heat treatment can probably be expected. That being said, Larrin is the best source of consistent, objective data and metallurgical interpretation for steel comparisons.” To quote Karl_H in
https://forum.spyderco.com/viewtopic.php?t=87383

“SPY-27 will hold the fine edge longer… Its all about the stability of the fine edge, not the total wear resistance until fully dull. In this regard, SPY-27 can do what other stainless steels cant.” to quote Submicron in the same thread.

I am aware that Cobalt’s dust can be an health issue. Of course Rex 45 and Maxamet (10% of cobalt, 1,5% for SPY27) are the heavy weight steel in their tool steel category but the Spy27 (like VG-10), like all cobalt alloys needs to be carefully cleaned after a sharpening process.
(Cobalt may cause an asthma-like allergy. Future exposure can cause asthma attacks with shortness of breath, wheezing, cough, and/or chest tightness. * Cobalt may affect the heart, thyroid, liver and kidneys. * Repeated exposure to Cobalt dust can cause scarring of the lungs (fibrosis) even if no symptoms are noticed. According to https://nj.gov/health/eoh/rtkweb/documents/fs/0520.pdf)


Let say SPY-27 is in the same club as the S35VN steels in terms of performance and it especially loves fine ceramic and leather stropping. It gets easily a very crispy edge like VG10 or BD1N . ( Steel which are “leather super friendly” are also LC200N, 52100, VG10, AEB-L… )
This is a must and a real pleasure for me as I keep my knives sharp mostly with leather. A touch up and it makes flying hairs from my arm again.
And it seems true so far. I have not deshouldered the edge yet and intend to use it with the factory edge for some times but leather made it hair popping sharp. (Once deshouldered it is a straight razor with excellent edge retention… much better than S30V).
To quote Sal:
“SPY27 for some reason, seems to be punching above its weight.”

No crossroads, this Blue Djinn loves leather like the Bill Moran FB01 in VG10 loved it.

No need to use diamonds unless you want to reprofile the blade or round the shoulder then don’t forget to rinse the blade and to clean any dust.
But talking about dangerous dust, I have sanded the scales to preserve my pockets. Never breath that dust !!! Do it under water or wear a mask.
I got a neighbor who has been working around that kind of heavy dust and now he is breathing with two tubes in his nostrils. So be careful with your health.
This Blue G10 got a very nice texture under the thumb like some denim, textil like. It is really pleasant, almost like some Micarta found on the QSP Penguin.

So when you sand G10, just go outside in the wind or work under water. You don’t want to breath G10 dust made of fiberglass and epoxy.
Just rinse it under the tap to have it back to normal.
Once tuned at your hand, G10 is a very very nice material.

As you can notice the scales are even thicket than the blade and the blade is perfectly centered.

There is the famous middle/half stop when closing or opening the knife. It works like a safety measure. This knife is harder to close than to open.

The UKPK is a very ergonomic knife. It feels like it melt in the hand. It is so confortable for heavy cuts. Because this blade can work hard with zero play.

The “pistol grip” is common in many Sal Glesser design like the Endura or the Military. It is much more pronounced on the Massad Ayoob.

No hotspots for me a very safe handle, really, this lil slipjoint is screaming to be used hard.

It is even confortable edge up.

With the Roadie XL. Another great Slipit with a very low profile, almost like a pen in your shirt pocket.

And the mighty Chaparral serrated. Two of Sal’s best designs. Two wolves in sheep disguise thanks to their thin solid blades.

I have decided to de-shoulder the edge for a gentle convex result in the middle of the belly.

My old leather with some polish compound is ready again to smooth the edge to razor level.

Because I want a better touch on the leather, I usually keep the normal edge at the point to keep material there and near the ricasso as I use this portion for special shores like removing the aluminium cap on bottles.

The Coke Bottle Butt test is passed with flying colors. As you can notice the plastic is 3mm thick. Not a single scratch on the blade.

So what do we got so far ?
A master piece of knife design by monsieur Sal Glesser with a strong construction and state of the art in-house alloy serving a thin blade and an ergonomic handle.
My advice: try to grab one before they disappear, it seems that G10 version is not here to last and it is really a sapphire: a true blue jewel !

Spyderco Chaparral C152SGY – For the Fierce and the Furious

3 Comments

Like I had mentioned in the glimpse review of the Serrated Chaparral, this little, thin folder is built to punch above its weight. Thanks to its sturdy construction and relatively strong stainless steel — the same type found on my Cold Steel Recon 1 XL — it can be tested and used like a much larger knife without compromising performance.

Solid steel, sturdy lock? Not much difference from a larger knife, in fact. 😉

So far, I’ve put the knife through its paces, cutting anything I could, and maintaining the edge with some Jade stones (see first picture). The mechanism shows no signs of play in any direction — rock-solid performance.

The plastic is thicker that the blade.

As you can see, the serrated edge is a chisel grind, which means it tends to deviate slightly to the right of the material being cut, much like a fin in water. I started the cuts with a bit of sawing, then transitioned to push cuts, and the knife effortlessly sliced through the thick plastic used to form the bottle.

This little knife is fierce in term of cutting performance. It is a lot of power in your pocket ! It is a pocket chainsaw !

The serrations really shine on the plate. You can push the knife hard against ceramic surfaces, and if the points ever need a touch-up, a few passes on a ceramic corner — or in my case, a jade corner — brings them back like new.

I have been able to reach razor level just by passing gently the Jade on it.

Actually it is fun to enhance the edge.

Actually, this is a bit of a comeback for me with serrations, dating back to my AFCK experience 25 years ago. Back then, I mostly used partly serrated edges, which helped initiate cuts on hard materials.

With a fully serrated thin blade and no plain edge, I initially wondered how useful it would be in the kitchen — especially since my wife’s favorite knives are Victorinox fruit knives (serrated). But it turns out, neither fruits nor vegetables can withstand the sharp, wavy edge of the Chaparral.

Funny enough I have been able to strop the edge of the Chap by using the side of the leather belt. CTS XHP is a steel which loves leather in my experience.

All in all, so far, so good. The Chaparral delivers impressive cutting power. Its thin, fully serrated edge is unique within the Spyderco line, pushing the design out of its comfort zone — and for a “knifeaholic” like me, that’s pure fun.

The next step is to trust this little knife enough to take it on a road trip in Italy — handling food prep, wood, and low-profile carry as my only pocketed folder. The Chaparral will make its return in May.

Spyderco Chaparral Serrated C152SGY- The Lightweight With Teeth.

8 Comments

I’ve been an early adopter of the Chaparral. Nearly 13 years ago, I called it the “Extra Flat Companion” in my first review from 2012. Back then, the Chaparral was designed to serve as a platform to test different handle materials, while the Sage (another model “made in Taichung”) showcased various lock designs used in folders.

Twelve years later, Spyderco has introduced a major improvement to the Chap’s blade: their famous serrations. The brand is, of course, known for its Spyderhole, its clips, and… the performance of its serrated edges. Sal Glesser has long advocated the superior cutting performance of Spyderco’s sserrations. Scallops, moon quarters, and thin chisel geometry all work together to create the ultimate “matter separator,” making tough cutting tasks effortless.


Sal has refined his serrations into a recognized patterns and created the Spyderedge: “Spyderco’s two-step serration patterns consist of one large and two small serrations. The pattern increases the cutting edge’s surface area by up to 24%”.
On the Chaparral, the serration are even better as they are rounded to avoid snagging when cutting. Those same enhanced serrations can be found on another serrated folder made in Taichung for Spyderco: the LC200N made Caribbean.

I’am not a serration’s fan. I prefer a short convexed blade like my Roadie XL to EDC but this is the opportunity to pocket a serrated knife designed to be low profile folder easily displayed in the middle of the sheeples.

The Chaparral is another Lil’ Big Knife in disguise. Go figure, his lock is equipped with an hidden pin which gives a lot of strength and stability. This improved backlock is also found on the Sage 4 but do not worry about vertical play.


Also the Chaparral’s blade is only 2 mm thick. A razor blade with serrations ? It should be interesting !

It even has teeth on its handle. The FRN scales feel almost like shark skin, which can be tough on pockets. My first step was to temporarily remove the pocket clip, then sand the scales to smooth them out.

The FRN doesn’t react as quickly as G10 when sanded. I still ended up with a slightly toothy handle, but it’s much more acceptable to me. Of course, this is a matter of personal taste — many users will appreciate the aggressive grip the pattern provides. I, however, prefer not to carry a pocket shredder anymore.

Lately, I’ve discovered that I really enjoy knives I can carry in my denim watch pocket. The Roadie XL, which I can now flick open with a wrist, is the king of that pocket and I use it hard despite its small size.

But this little “Tooth Faerie”, the Serrated Chaparral, also demands heavy use — and beware of its cutting power! Its steel, CTS-XHP, is known for being extremely reliable, even on thin edges. I’ve used it in many knives, including some Cold Steel Voyager XLs, and it never disappoints.

It will be very interesting to see how the Chaparral Light platform, equipped with a top-performance factory edge and an improved backlock, performs as a true workhorse — pushing the envelope of what the Chap’ can do. Spyderco has also just released a Slipit (non-locking) Chaparral, sold at nearly double the price of the FRN serrated version. Clearly, this one isn’t marketed as a “precious” collectible but as a pure performance tool. Spyderco has supercharged the Chaparral to be a user’s knife.

To summarize:

  • 2 mm thick blade — this is thin !
  • Backlock enhanced with a hidden pin — zero vertical play !
  • Rounded, anti-snag SpyderEdge.
  • Sheeple-friendly design.
  • Made in Taiwan with attention to details.

Yes, the Chap is back… with teeth … in its next chapter:

Spyderco Roadie XL C267BK – Part II – Shattered Tip.

2 Comments

M398 is a fragile steel compared to M390. The encounter of the tip of the Roadie XL with a tile of my kitchen has been definitive. One mm has been shattered and now I got a micro flat screwdriver as a tip.
OK. Diamonds are steels best friend.
I’m able to form a new tip in a diamond shape.

For now I won’t baby that Roadie XL anymore. I decide to thin the edge.

The best way is to protect the blade to avoid any big scratches.

Then it is time to play with industrial diamonds.

I will also use some diamond rod to round the jimping.

Of course I’m enough clumsy to scratch the blade twice and I’m obliged to use some diamond paste to treat the surface.

Then some polishing paste on the leather to slowly makes it like a mirror.

I’m quite happy with the result.

Time to test this new geometry. The edge has been convexed and thinned it should cut much better.

One of the most difficult task is to cut in two the butt of a two liters plastic bottle. This is a test my Scandi blades fail all the time. Any Opinel is king in that. Or the Manly Wasp ! My favorite being the Nilakka.

As a whittler it goes deep in wood.

As a steak knife, the shape of the blade brings only the new tip in contact with the ceramic of the plate.

That new tip is strong enough to be able to pierce a metal lid of a green bean jar. A hole pierce help the release of the lid on some jar.
No damage no more.
Now the Roadie XL cuts much butter.

Spyderco Roadie XL C267BK – Size matters

3 Comments

Six years ago, I reviewed the Working Poney, also known as the Roadie. Mine had been reprofiled by Jan Dirk, and even on its tiny scale, it proved to be an outstanding performer. For six years, it quietly stowed away, accompanying me across the UK, Vietnam, and countless places where knives were frowned upon.

Then, in 2024, I noticed the announcement of an XL version — the C267BK — featuring a better steel and a clip. Right away, I saw the new pointed blade, replacing the classic sheepfoot-style blade, now ground from Böhler-Uddeholm N690Co. Even more exciting, the XL uses M398, an exotic steel reserved for flashbatches — a serious step up in terms of performance and collector appeal.

And so, here it is: Ladies and gentlemen, the Roadie XL !

They say an image is worth a thousand words, so here you have 4,000 words with no syntax or spelling errors.

Back to the Roadie XL: it is made in Maniago, Italy, just like my Nano and many other excellent knives these days. The Maniago plant remains one of the best worldwide in terms of quality and precision.

Specifications:

  • Overall Length: 6.51″ (165mm)
  • Blade Length: 2.74″ (70mm)
  • Steel: M398
  • Closed Length: 3.76″ (95mm)
  • Edge Length: 2.31″ (59mm)
  • Weight: 1.5oz (43g)
  • Blade Thickness: 0.108″ (2.8mm)

Its shape and size make it extremely pocket-friendly, easily fitting into the watch pocket of a pair of denim jeans thanks to its deep-carry wire clip. You could remove the clip, but why? It keeps the knife perfectly on the pocket’s lip. The clip is also reversible, though that’s not mandatory for a two-handed opening folder.

With its thin profile and light weight, combined with the clip, the Roadie XL can even be carried in a shirt pocket like a pen. In short, it’s a knife meant to stay on your person almost unnoticed.

The action is smooth, with two stops/steps before the blade fully opens. In practice, it feels smoother than my Urban, which only requires a single hand to deploy.

With a slightly longer blade than the Urban, the Roadie XL remains legal to carry in countries such as Denmark, the UK, or Germany. Mine arrived razor sharp straight out of the box, so I’m in no particular hurry to convex the edge.

Mine came razor sharp right out of the box. So I’m not in a special hurry to convex its edge.

You can immediately recognize Sal Glesser’s signature design—a clear mark that it’s his invention. Sal is an inventor, and it’s always impressive to see how he manages to create clever, practical tools. Quoting him directly:

“When the Transportation Security Administration (TSA) briefly considered allowing the carry of knives on airplanes again, Spyderco designed the Roadie™ to fit their guidelines. We created an incredibly popular modern expression of the classic penknife. Since bigger can indeed be better, the Roadie now has a big brother: the Roadie XL. It faithfully offers all the defining features of its smaller counterpart—including a non-locking “notched-joint” mechanism, a textured index-finger choil, and contoured, injection-molded handle scales. Its full-flat-ground sheepfoot-style blade is crafted from M398 stainless steel and features our distinctive “Double Dent™”—a pair of symmetrical dimples in the blade that provide a solid purchase for a fingernail-free two-handed opening. In addition to its larger size, the Roadie XL also adds a deep-pocket wire clip for convenient top-of-the-pocket carry.”

Now, let’s talk about M398, one of Spyderco’s premium powder metallurgy steels, only available in limited flash batches, all made in Maniago, Italy.

From what I understand, M398 is closer to CPM-90V than to M390. Quoting Darrin Thomas’s analysis (which is worth reading in full):

“The original M390 has a reported carbide volume of 20.5%, and the new M398 has about 30%, so there has been an increase in carbide of almost 50%. We would expect this to lead to a significant reduction in toughness along with an increase in wear resistance. The datasheet shows that the toughness of M398 is only about a third of M390, though at somewhat higher hardness. So it is apparent that the design of M398 is all about wear resistance and essentially ignores toughness. M390 has only slightly lower toughness than K390 with similar carbide volume (though K390 was tested at 62 Rc). M398, on the other hand, has significantly less toughness than the similar carbide volume S290. However, M398 does have some positive traits, such as increased hardness and reduced retained austenite relative to M390. I’m personally not all that interested in yet another high edge-retention steel that sacrifices toughness, ease in sharpening, and workability. We had other options and this initial look doesn’t make M398 appear to be an improvement over the other available steels. M398 was a relatively simple modification of M390 and I can’t help but think that a more optimized version could be made. M390 did offer similar toughness to cold-work tool steels like K390 with a similar carbide volume, but M398 has significantly lower toughness than the similar carbide volume S290. So M398 doesn’t appear to be over-performing relative to its composition and carbide content. I wrote about some Bohler-patented high wear resistance steels using niobium instead that look very interesting but haven’t seen a commercial release. Those steels would be breaking new ground and potentially offering new property combinations not previously available. But if Bohler pushes out M398 more broadly it will be interesting to see how knifemakers utilize the steel for applications that benefit from high wear resistance and edge retention.”

When M398 was used in a previous flash batch for the SpyMyto, I wasn’t particularly excited—it felt like overkill for a folder that seemed built for hard use. The Myto is essentially the big brother of my Nano made in CPM Magnacut, and a SpyNano in M398 is also on the bench. In comparison, Magnacut is far tougher than M398, making it more suitable for wide, workhorse blades.

On the Roadie XL, though, this is a different story. Like with my Heinie Urban in S90V, these small blades are not intended for bushcraft—but some highly skilled bushcrafters can make miracles with even a 2-inch slipjoint, as shown in an inspiring video I recently saw.


Slip-joints are gentle companions for both ladies and gentlemen. For those with long nails, the Roadie XL is equipped with its distinctive “Double Dent™”—a pair of symmetrical dimples in the blade that provide a solid purchase for a fingernail-free, two-handed opening.

Its high wear resistance comes in handy, as these small blades often encounter cardboard, which can be surprisingly abrasive. I also recall Roger, my father-in-law, wielding his old Pradel slip-joint like a crowbar or flat screwdriver, without a second thought. Old-timers often treated knives mercilessly, using them until the blade was as thin as a needle.

I’m confident the Roadie XL with its M398 blade would make an excellent hare skinner—the fur is full of sand that can destroy an edge almost instantly. Tuscan hare hunters would likely appreciate its durability. Its high wear-resistant alloy makes perfect sense here. Additionally, the blade is relatively thick at 2.8 mm, which would otherwise be prone to breakage.

Ergonomically, the Roadie works beautifully for a slip-joint because you can hold the blade by its choil—a feature rarely found on traditional slip-joints. Even most Swiss Army Knives lack that level of security, and with M398’s toughness, the blade cannot close on your fingers. As Spyderco notes:

“Unlike traditional penknives, the Roadie also features a subtle index-finger choil that increases control of the knife during use and acts as a safeguard against unintentional closure.”

There’s no undue pressure on the pivot, often the most delicate part of many folding knives. If you are careful not to twist the point in wood, the Roadie XL can withstand applied force directly to the blade. This makes it another “Lil Big Blade”—small but versatile.

It can serve as a steak knife, whittler, label remover, balloon popper, nail cleaner, or cardboard cutter. Brown cardboard is notorious for edge damage, but not for an alloy like M398, packed with carbides.

And in today’s world, one more practical advantage: it is extremely sheeple-friendly. The Roadie XL looks like a pocket knife, not a tactical or soldier’s tool, making it socially unobtrusive yet highly capable.

Roadie, K390 Pingo, S90V G10-Urban and Roadie XL (all green letters mean they are linked to their reviews)

Beauty is in the eye of the beholder, but to me, this blade—shaped almost like a scaled-down cutlass—is pure eye candy.

Interestingly, I’ve discovered that I can open it one-handed in two distinct ways:

  1. A fast wrist flick while holding the blade itself.
  2. By gripping the blade with thumb and index finger and gently pushing the handle away with the middle and ring fingers.

So, even though it wasn’t designed as a one-hand opener, the Roadie XL can function surprisingly well as a one-handed knife in either technique.

Compared to a traditional sheepfoot slipjoint, the Roadie XL is incredibly light yet sports a premium alloy blade (Since August 2025 another slipjoint with M398 is available: The Metropolitan.).
And at under 100 euros, the Roadie XL is an exceptional bargain for what it offers.

This is one of Sal Glesser’s finest EDC designs—a true Every Day Carry folder that balances elegance, utility, and performance. And for once, size really matters with a Roadie. No wonder it’s already sold out on the Golden site!
There is part II here.

Lion Steel Nano – A closer look at the Dwarf

3 Comments

One week later with Thorin in the pocket (Tolkien fans will know) I can now say: “What a great EDC knife !”.
And especially after each use: “What a cleverly designed cutting tool !”
Of course, I have noticed some nagging about the fact that the ball bearing are not made of ceramic but I remember reading also many issue about the Spyderco Mantra 2 and mine was just getting better and better the further I have used it.
The same for the Nano. It flipper fires now at 100%.

Now the Dwarf has proven to be exceptional in regard of pure ergonomy. This is the knife which has been thought as a tool you can handle for a long time making it a great candidate for wood working and even for various bushcraft uses.

As you can notice the handle got that “elbow” near the end which makes it simply nesting in the palm of my hand.

See ?
It was the same idea on the Casström‘s handle, a knife which is a pure Bushcraft’s tool.

This detail in the way the knife is designed changes a lot in terms of the comfort of the handle in your hand.

Another really nice touch is the way the flipper is integrate to the handle once the Nano is open.

The flipper almost disappear in the handle. It flushes better than on my Amalgame Bowie.

This dwarven knife is done for hard uses and tough work. The blade has a wide full flat grind on almost 4mm thick stock which is really powerful in term of push cutting.
Like the dwarves in Tolkien’s books, you cannot judge the Nano by its size.

This little big knife has a handle to grip hard and a short blade to cut hard.

Also the edge of that CPM Magnacut blade once convexed is easy to maintain crispy only with some leather. Apparently the heat treating has been really well done by Maniago people.

The excellent geometry makes it a breeze to use on soft material also.

The open construction makes it easy to clean.

For the better actually. Titanium and Magnacut are not easy to stain anyway. You are not obliged to clean it immediately. Then under some hot tap water, it is back to new.

So really, so far so good, Thorin the Dwarf (“Nano” in Italian) is delivering and is not a disappointment at all but an excellent surprise. It goes in the same category as the Spyderco techno. Short tools with a lot of power are precious and not easy to design well; a folder short enough to sit comfortably in the watch pocket and with its pebble shape won’t rise any sheeple eyebrow. That’s a gem !

LionSteel Nano, NA01-BL – Magnacut Blue Lil Big Knife Made in Italy.

2 Comments

I’ve been eying the Nano from Lionsteel for almost a year now.
Magnacut and Titanium framelock made in Maniago in compact package is very very tempting.
Lionsteel has decided to invest a lot on the “darling of all steel” aka the CPM Magnacut and you can find a lot of their new collection in that wonder steel. Lionsteel is also known for a very high quality in manufacturing.
I had already reviewed a MKM designed by Bob Terzuola made in the same factory.
Also I was a huge fan of their great collaboration with Spyderco on their LionSpy great knives.

So, back to the Nano: what not to love in this chunky little big knife ?
Magnacut and Titanium encapsulated in a beautiful well thought Italian design ?
Amore a prima vista !

See how it is beautifully crafted ? A picture worst thousand words.

Nano by lionSTEEL, technical specifications from their site:

Total length: 162 mm. – 6.38 in.
Blade length: 65 mm. – 2.56 in.
Blade thickness: 3.8 mm. – 0.15 in.
Total weight: 101 gr. – 3.56 oz.
Blade steel: CPM MagnaCut
Blade finish: Satin finished
Locking system: Frame lock
Frame: Gray titanium
Handle material: Titanium 6AI4V 
Handle colour: Blue
Packaging: Cardboard box

The hardness is 63HRC according to this video from CBRx.

This is designed to be the “ultimate every day partner” quoting Lionsteel.

For me it is the Italian answer to the Spyderco Techno. even the upcoming Techno 3 looks a lot like the Nano !
It is an ultra solid short fixedblade with a strong lock and a strong steel.
The stop pin is hidden like on my Swayback.
A natural born workhorse at 200% ! A Landrover in a Ferrari skin !
Zero play, vertically or horizontally. Build like a tank.

Let’s flip it.

The flipping action is not the best out of the box despite its  the Double Crown ball bearing system. It perhaps needs a drop of oil ?
Edit: with a drop of teflon oil (for bikes) it works fine now.

Any way the flipper is not the main way to open it.

There is a notch in the blade which is totally useable to open it one hand.
I’m able to notch drop opening my Nano.

The flipper is removable and it is called the “ReF” (Removable Flipper system). “The Removable Flipper system let the user decide if the flipper tab has to be part of the blade or not. The tab can be installed when in need, or removed and replaced with the second “cap” screw.”

I intend to keep the flipper also works as a little guard.

Zero issue also to close the knife.
“The titanium frame locking bar is reinforced with a hardened steel insert so that the titanium part doesn’t get worn by the rotation of the blade in time.”

Nice touch and a tech totally mastered by Maniago !


Out of the box it is sharp.

Magnacut loves leather and it will soon be stropped. See the edit at the end of this article.

Now about the clip.

The clip is gorgeous and very solid.
“The clip comes out a single piece of Titanium CNC milled. It is reversible, so it can be fixed on the opposite side for left hand users.”

But it is very hard to clip and unclip on my denim thick pocket.
This is almost tedious. Not a big deal but for a serial clipper like myself the Nano will prefer thinner frabric to get clipped too.
Anyway, as a small knife it can go easily the pocket without being clipped.
The clip does not ruin the ergonomy and this is also important to notice. There is no hotspot once closed or open.
Edit: I was skeptical about the thinner “edges” on the handle, as a square handle proposes more flat side like on a Native for example.
But no, the handle is confortable even when cutting in hard material.

The handle is exquisite with a lot of attention to the details. It looks and it is a premium folder. It is exquisite ! And for the price (I got mine discounted at La Coutellerie Tournagell for less than 200 euros) it is a steal !
That kind of top notch manufacturing in my favorite USA brand would be much expensive, even made in Taiwan.
The Nano is a bargain for the very high quality it is offering.

The blade spine is rounded like a Chris Reeve Sebenza !
So confortable for pushcuts using your thumb.

Testing on a piece of hard wood, the geometry is excellent and it goes deep right of the box. Magnacut being strong and easy to maintain sharp, it is a wood worker knife by essence.

The Nano offers also a lot of blade, a tiny bit more than my Native for great handle/blade ratio.

So this was a first glimpse to my 35th SICAC found which has just jump out of its box.
It is a short knife with a lot of cutting power and an exquisite design and realization. Kuddos to Lionsteel and Pauletta Gianni for this absolute ge of a knife.
Mine is blue. “Nel blu, dipinto di blu”.
And I feel like “Felice di stare lassù !”

Edit: I have decided to deshoulder the edge and start to turn it into a convex edge as usual on my knives.

Using a DC4 from Fallkniven and protecting the blade with gaffer.

And it goes through the bottle butt ! Right in the thickest part.

To Quote Prince in his song 1999: “I got a lion in my pocket and baby he’s ready to roar, yeah hey.”

Edit: There is a video of CBRX which I highly recommend to discover the insides secrets of the Nano. Very informative !
