C127GPRD SPYDERCO URBAN HEINNIE® EDITION – The S90 Urban UK Legal Wonder.

5 Comments

The Spyderco Urban, Squeak, and UKPK family are the most addictive slipjoint lineups in the modern knife world. I have already written about them on this blog. The UKPK Salt is simply one of the best modern folders available nowadays. The Squeak is totally sheeple-friendly, and of course the Urban was made for city carry and can be carried almost everywhere except on airlines.

Spyderco’s description:
“This Exclusive version of the Spyderco Urban™ was manufactured specifically for Heinnie Haynes (heinnie.com) and is available only through their sales channels.  Originally introduced in 2009 and later discontinued, the Urban remains a cult classic among devoted fans of Spyderco’s non-locking, one-hand-opening, clip-carried SLIPIT™ knives. This distinctive expression of it showcases a leaf-shaped blade crafted from premium CPM® S90V® particle metallurgy stainless steel. The PlainEdge™ blade is full-flat ground for exceptional edge geometry and is proudly laser engraved with the Heinnie Haynes logo.Not to be outdone, the handle of this knife features distinctive red G-10 scales with a non-slip peel-ply texture. They complement the jimping (textured grooves) on the blade’s thumb ramp and index-finger choil to ensure a positive grip and outstanding control during use. A reversible deep-pocket wire clip provides a choice of left or right-side tip-up carry, making every aspect of the design completely ambidextrous.”

This red one is my third Urban. The first one was in K390, the second one was in AEB-L and was named Cappuccino. All of them were eventually pushed out of my pocket because of the greatness of the UKPK Salt in LC200N.
Still, they have all been great companions during my travels in the UK, as they are fully legal: non-locking knives with blades under 3 inches (76 mm)…
Eventually, I started looking for a G10 version with a full stainless steel backspacer, and I found the Heinnie Haynes exclusive version available on their site. It is not a cheap knife, be aware of that, but it oozes quality both on paper and in hand.

First things first, this Urban features a CPM S90V blade, the same steel found on the Proficient bushcraft knife. S90V was previously known as CPM420V, and it remains one of Sal Glesser’s favorite steels ever produced by Crucible.

S90V is famous for its incredible edge retention, and after 25 years of using it, I can tell you that it can also be a bear to resharpen. Diamonds are its best friends, and even then it requires a lot of white ceramic work and stropping… Compared to non-stainless super steels like Maxamet, it can be quite tedious to bring back to a truly razor-sharp edge. But once sharp, its working edge seems to last forever.
This is exactly the opposite of my previous experience with Cappuccino, my AEB-L Urban. That knife was tough and incredibly easy to keep razor sharp, but it quickly lost its edge when used on abrasive materials like cardboard.
S90V eats brown cardboard for breakfast and stays sharp for a very long time, but it takes patience to bring it back to a crisp razor edge.
That is excellent when you need a long-lasting working knife on a trip where you did not plan to bring sharpening equipment. Sal Glesser trusts S90V enough to use that alloy on many of his own special Sprint Runs with carbon fiber handles.
I have never been disappointed by S90V. Even on fixed blades or on the Manly folders, it has always been a game changer in terms of long-lasting sharpness, and in my experience it even surpasses CPM 10V.
S90V is also highly stainless. Unless you plan to use your knife in the ocean, it can handle demanding work in the forest without needing immediate cleaning.
It has also been noticed that this S90V Urban features a slightly thinner blade: 0.23 cm instead of 0.29 cm. The blade is also slightly shorter than previous Urbans, although I have not noticed any difference in real-world utility.

This Urban was made in Italy, and in my personal experience, Maniago craftsmanship has never been a disappointment. Your mileage may vary, but this has been mine. I have always been happy with my Spytalians!

G10 is not a common material on Urbans, as FRN dominates the lineup, and the texture of this G10 is even more distinctive. At first, I considered turning this knife into a smooth “pebble,” but… nah! It is great as it is.
I only adjusted the feel slightly by sanding it, but overall this is a beautifully made, high-quality handle — once again, kudos to Maniago.
All Heinnie Haynes exclusives feature this red treatment on the handle; it is their signature. The G10 version also benefits from a longer steel backspacer that closes the handle construction more completely.

Now about the action: this Urban has the strongest spring of all my slipjoints! That is actually a very positive point. I can still open it with a quick wrist movement, but closing it requires real force, which is rather rare — even in Spyderco production. (The first UKPKs were “chewing gum soft,” to quote Guillaume, moderator of the Spyderco Fan Club.)
A strong spring combined with the absence of a lock makes it a great candidate for legal everyday carry nowadays.

Now regarding geometry, Maniago deserves another round of kudos! As you can see in the picture above, I was able to split a bottle bottom in a single pass with the factory edge. That is also rare! Even my beloved Hellboy needed some thinning before reaching that level. This is thin geometry straight out of the box!
The short drop-point blade makes it an excellent whittler, and Spyderco truly knows how to make little big knives. The hump and choil transmit your cutting force directly into the blade, sparing the handle, pivot, and mechanism. It is a clever design, inspired by the old San Francisco gambler’s knives. Sal’s first implementation of this “cockpit” concept dates back more than 30 years to the C36 Military.
The choil-and-hump combination is brilliant for preventing a non-locking blade from closing onto your fingers. To me, it is an absolute must-have!

So here we have a legal folder with a non-threatening blade, a strong non-locking spring, excellent cutting geometry, and stellar particle metallurgy steel.
What is there not to love about this wonderful Urban?

You can cut a pizza on your plate and use it as a steak knife without raising any eyebrows. I use my knives directly on plates, and I know how to avoid dulling them on ceramic. My mother-in-law never places a knife near my plate anymore — that is how I can spot where I am supposed to sit at her table.

The Urban also has the perfect size for carrying in a Levi’s 501 watch pocket, and as you can see, mine has been shredded over time by many aggressive G10 handles before extensive sanding.

So yes, I highly recommend this excellent exclusive little knife. Again, it is not cheap, but the quality is there from tip to clip.

Spyderco Native Chief: HELLBOY 2 – The Kitchen Army

5 Comments

Since the reception of my Chief Native I have found that he was a sole survivor from a Xmas Mystery Box bought in Spyderco’s plant in Golden in December.
In that box were different items and a rare Sprint Run Second Factory which was destined to end in my pocket and considered by myself IMHO as the perfect realisation of Sal and Eric ideas about pocket knives. In fact I think it is my favorite Spyderco ever.
I have written a first review here.
And now it is time for a second approach of Hellboy which has succeeded in kicking other knives from my pocket and quench my thirst for novelty.

So why ?

First the Native family feature an absence of hump on the blade making them very slick and beautiful.

Even the Shaman benefits from that.

The Chief is on the left and the Shaman on the right.

As you can notice the design of the Native Chief is really close to one of my favorite design: the AFCK.
Sal Glesser was no stranger in the Benchmade BM800 AFCK back in the 90’s. He helped Les De Asis founder of Benchmade on it. They had both learned how to make Michael Walker’s linerlocks at Bob Terzuola shop.
Both company were accelerating on the tactical lane in close formation.

As you can notice, my AFCKs (Advanced Folding Combat Knife) which was also designed by Chris Caracci a former Navy SEaL have been used a lot. The first version got a Spydiehole and the second version got an oval hole and an axislock.
This design was one of my favorite for a big folding knife as EDC.
And back then I was really in love with concept of tool highspeed steel on a modern plateform.

The same happend with that special Native Chief which got a very special alloy for its blade: CPM-4V.
With that steel, the edge is strong and the thin blade is very solid.
It gives a lot of confidence when cutting on a plate made of ceramic of glass. No chipping can happen.
Hellboy has been used a lot for cutting pies and cake on glass plates and the edge behavior was not disappointing. When I have noticed a little shiny spot, some white ceramic was able to put everything back on line but it was really minor.

Now CPM4V is not stainless. It will form a patina or, worst, rust very quick and easily when used in acidic matters like cutting lemons and being used on a salad with vinegar.
DLC coating is really welcome for that kind of behavior. Back in the 90’s Benchmade was offering only PVD coating which is really inferior to Diamond Like Coating. So far the blade of my Chief is not marked and scar by it various cutting tasks even when cutting.
My previous Chief was a naked Rex45 blade and it was another story told here.

Even strawberries can darken the edge of CPM 4V.

But cheese is a great way to notice how DLC is making the surface of the blade less sticky but more stinky.

The Chief was not always used on gentle medium like wood.

It was also used on plate with vinegar salsa. Here it is basamic vinegar from Modena.

In the kitchen the knife is really behaving like an paring knife. It is really handy on fruits and vegetables. Its very pointy blade is great to carve.
.The mechanism has never suffered from being wet and rinsed under water. The knife was smooth through and through its various wet works.

Now I like to have chamfered and smooth handles and blade spine. The Chief is known to be very square everywhere. The G10 has been easy to smooth with sandpaper used wet to avoid toxical dust.
Now the blade spine is DLC coated and it was my esthetic choice to remove the coating on all the length of its spine.

I love the result.

It has been done with some diamond rods.
Now the spine is much more confortable for my thumb in case of push cuts.

CPM 4V on that Native Chief platform is really the bread and butter for a strong thin folder. I’m not afraid to use hard on wood and plastic.
And it is a must in the kitchen various missions.
It has been also test on different hard wood and compared (geometry speaking) with many other knives I got.
One of my champion is the Swayback in term of smooth pushcuts.
But also the Wolfspyder and the Yojimbo.

My Chief needed more convexing and thinning to go to the level I was expecting. Again diamonds has been used handfree to remove the shoulder of the edge.
CPM 4V keeps a very very crispy edge and bites in the wood very aggressively.

CPM M4 is a stunning alloy which is prefered on fixed blade but it is a gem on a long and thin folder. It makes it super solid with a very permissive edge.

Quoting Larrin Thomas Phd:

Some will argue that toughness is not important in folders or fine slicing knives and feel that only edge retention matters in that case because they don’t use their knives in aggressive ways which are likely to lead to chipping. However, broken tips are still common on small knives and kitchen knives. And with higher toughness, the knives are better able to handle thin, low angle edges without chipping. And they can be heat treated to higher hardness to help prevent edge rolling and deformation, while still maintaining good toughness. This means that, indirectly, higher toughness can lead to better cutting performance because of the possibility of thinner edges.

The good news is that CPM Magnacut has been copied on CPM 4V behavior.

Delica K390 with Lynch Titanium Scales – A Wolf in Sheep’s Clothing !

Leave a comment

I got the chance to get that customized Delica through Henri Ramsey, a Spydiefriend from the Facebook French Spyderco Fan Club.

The K390 Delica has always been a monster of pocket knife (click on the name to go to my old review of the Delica with buffed sprint alloy). The thin blade mixed with the super tool steel allow (K390) alloy has proven to be amazing for hardchore.
From their Seki Japan plant, Spyderco is producing many different K390 model, folders and fixed blades. The Stretch 2 being highly regarded as one of their best design.

The Blue Pingo has been made in Golden though.

So here you got an incredibly tough, strong and wear resistant blade on scales produced by Lynch. A typical Sal Glesser design: performance first !

But Lynchnw has taken that game to another league with their scale:

“A few years ago Casey put out a very limited run of the LynchNW MOD 1 Delica 4 and some scale sets. This is our newest Delica MOD 2 Titanium Scale Kit, modifying your choice of Delica 4 Knife with a set of Custom Titanium scales, featuring a forward finger choil, blade profiled scale holes, smooth bellied profile, a custom titanium back-spacer, enlarged lanyard hole, and a custom designed deep carry titanium clip. ” To quote Lynchnw.com site.”

What bring these new scales apart of adding titanium for the pure neo industrial look of it ?
It bring many things:

A finger choil. A real one.


A longer handle and your pinkie will thank you for that.


A slim package which is soft on your pocket trousers.


Seven holes which are showing the edge of your knife when it’s closed.

See how cute is it ?

So here we got a very friendly city pocket knife which is not screaming “I’m a sword from Hell !!” like my new beloved Hellboy Chief or this AFCK in M2.


It looks like a lady and gentleman knife.
But beware of the wolf in sheep’s clothing.

This one share the same core engine as a Police 4: K390 at 65HRC in a thin geometry ! It is a Metropolice knife.

Deadpool’s choice: the C244GRDBK Spyderco Native Chief in CPM 4V.

5 Comments

This is my second Native Chief, and it is a Factory Second bought in a 2023 Mystery Box:
“This limited-edition Exclusive version of the Native Chief™ was specially manufactured for St. Nick’s Knife Factory (stnicksknives.com) and is only offered through their sales channels.…
…Our Red & Black Holiday Sale starts December 1st at 9:00AM MST! This online-only event will feature deep discounts on select factory-second knives, two different Mystery Boxes containing seconds of special high-value models, Sprint Runs, and Exclusives.“
Red and Black? This one was definitely made for that box! 🙂

Which means it has some cosmetic flaw I was not able to spot.
The action is rock solid — in fact, much more solid than my previous Chief, the Mighty Rex 45 Orange Sprint Run: the Joker.

I have heard that CPM Magnacut could be a stainless CPM 4V.
What I have heard over the years is how CPM 4V is tough and strong. The toughest steel used in Spyderco was CPM 3V used in the Tuff by Ed Schempp.
4V is used in cutting competitions alongside CPM M4. It is tougher than A2 or D2, and also tougher than M4.

What is the advantage in a folder like the Chief?
Simply look at the blade shape:

The Chief’s blade is more pointy than the PM2.
To quote Spyderco:
“This advanced alloy was specifically developed for demanding industrial applications requiring high degrees of both toughness and wear resistance. The PlainEdge™ blade is full-flat ground for a superior balance of strength, edge geometry, and point utility, and features a stealthy black Diamond-Like Carbon (DLC) coating that also helps protect it from corrosion.“

Yes, this is a good thing because with only 5% chromium, CPM 4V can rust.
DLC helps eliminate that concern for this folder.

There is also some reminiscence of the Benchmade AFCK in M2HSS.
It was 25 years ago that this co-designed folder with Chris Caracci and Sal Glesser introduced a rust-prone tool steel on a modern “tactical” knife, protected by a black coating.

So peace of mind is a real advantage in a workhorse knife.
In the signature theme of St. Nick’s Exclusives, the linerless handle of this knife is constructed with vibrant red peel-ply-textured G-10 scales. To complement the blade’s low-profile DLC coating, the four-position pocket clip, lock bar, and all other handle hardware also have durable black coatings.

So what do we have with this Hellboy’s blade of choice?
A long folder with no hump on the blade — very slick.
A tough, pointy design you can use hard.
A very strong lock — backlocks are among the strongest locking systems around.

Quoting Sal in my previous Chief review:
“Actually Eric and Tom went over this model with the engineers for quite a while before making the decision to make it liner-less. We’ve done a lot of experimenting lately and you can see a lot in the many different designs and options. It surprises me that some would think to make decisions on values without any experience. If we screwed it up, we’ll fix it, but we don’t screw up often considering the many envelopes we’re willing to push.”

Now that Spyderco is promoting a lightweight FRN version of the Chief in CPM Magnacut, this is a good opportunity to step back in time and enjoy this incredibly slick and tough piece of equipment from a few years ago.

For my own adjustment, I have sanded the G10 so it is less harsh on my trousers.

The edge is already de-shouldered with diamond stones, and now I will tune it further to my preferences, as CPM 4V is not only tough but also strong.

I also replaced the original clip with a deep-carry Chinese clone.

And off we go!

Edit: I am back on the OEM black matte clip, which keeps less of the knife in the pocket. Deep carry is not mandatory on this one.
The Chief needs to be proud to be red!

The Amphibian Milestone in CPM Magnacut : the Paramillie 2 Salt has landed !

5 Comments

The Amphibian Milestone in CPM Magnacut iq PARA MILITARY® 2 SALT® BLACK G-10 CPM MAGNACUT® BLACK BLADE – C81GMCBK2, which is much too long to fit in a title.

This is not my first Paramillie 2. I usually wear the 52100 carbon fiber version, but I have used many versions in S90V, CPM Cruwear, and S30V. The 52100 is actually the exact opposite of this new version.
Announced at the 2023 Amsterdam Minimeet, a Paramillie impervious to the elements. Better: a nautical version ready to stand tall in front of the salty waves of the ocean’s breakers.
Then the wait began.

And here it is, in all its glory!
Delivered with Larrin Thomas’ dreamlike alloy: the CPM Magnacut!
A steel that hits a lot of sweet spots. Like a sort of totally rust-free CPM M4: strong, resilient, and able to withstand thin edges without chipping.
So why add a DLC on that alloy? Overkill can be fun, can’t it?

Here are 3 versions. The 52100, the CPM Cruwear, and CPM Magnacut from right to left. Three excellences in their own way, all designed by Sal and Eric Glesser.
CPM Magnacut is a story of love.
Quoting its metallurgist and designer:
“The carbide structure of MagnaCut is much finer than the common powder metallurgy stainless steels such as CPM-154, M390, Elmax, S35VN, etc. The only stainless PM steel I have imaged which is competitive in terms of carbide/nitride size is Vanax. MagnaCut is even somewhat finer than CPM-4V and Vanadis 4 Extra, the non-stainless steels that MagnaCut was modeled after. This is an excellent result and should lead to excellent properties.”

Quoting Spyderco:
“This tour-de-force expression of the Para Military 2 showcases a full-flat-ground blade crafted from CPM MagnaCut—a state-of-the-art particle metallurgy steel that offers an exceptional balance of edge retention, toughness, and superior corrosion resistance. Cloaked in a non-reflective Diamond-Like Carbon (DLC) coating, the PlainEdge blade is housed in a handle featuring peel-ply-textured black G-10 scales machined with the signature Caribbean Bi-Directional Texture pattern of Spyderco’s US-made Salt Series knives. To complement its blade steel and finish, the knife’s nested stainless steel liners, four-position pocket clip, and all other hardware are also made from ultra-corrosion-resistant materials and black coated.”

That new Salty Paramillie is destined to be an amphibian workhorse, a hippocampus!!
All hardware is black coated except the stop pin, which is silver and made of “fearlessly corrosion-resistant marine-grade materials“.
The handle (as efficient as it is in being non-slip) is destined to be a pocket shredder, as it is carved to be used with wet, oily hands. Your trousers will suffer!!
Unless, like myself, you are a compulsive user of sandpaper. Even then, it will be hard on pocket lips.

The Diamond-Like Coating is not only protecting a blade that doesn’t need any protection; it also gives a strong Mall Ninja vibe.
Usually, coatings bring some kind of lubrication to material separation. I’m not impressed so far, even on sausages.
The geometry is perfect on my PM Salty—thin as a razor though.

One thing I had to change was the clip. It was replaced by a Flytanium Universal Titanium Clip, which is short and deep-carry.
Also, I moved the clip for a tip-up carry, which suits the Paramillie better in my book.

Of course, de-shouldering the edge is the first step before convexing, which I do on new knives. Especially since I have read that Magnacut loves leather stropping.

And this is true! The edge turned quickly into a über-razor state.

It zipped through meat like a lightsaber into bantha meat.

So now the game is on. The Salty Magnacut Paramillie is ready to kick all other knives from my pockets and be used long term.
Let’s see what this cutlery apogee-era knife has to propose in the long run!

Spyderco Dragonfly Wharncliffe K390 SC28FP2WK390 – Roar like a Dragon, fly like a bee.

4 Comments

Behind the code “SC28FP2WK390” lies one of the gems designed in-house by Sal Glesser. The Dragonflies are legion.
(All green text in this review links to related articles.)

Quoting Spyderco: “The Dragonfly 2 is one of the most size-efficient folding knives ever created, especially when expressed with a straight-edged Wharncliffe-style blade. When that blade is crafted from tough, wear-resistant K390 tool steel, the result is a compact powerhouse cutting tool that will take and hold an exceptional edge.

Like the standard Dragonfly 2, this knife also features a user-friendly back lock and a reversible deep-pocket wire clip, but its linerless FRN handle is molded in the signature blue color of Spyderco’s K390 family of knives.”

The Dragonfly is a very small locking knife that has been produced in many variations: stainless steel handles, Salt Series rustproof versions, and numerous sprint runs. This version uses a Wharncliffe blade in one of the finest modern tool steels available: K390. Such a capable steel on such a small, thin blade is always worth experiencing.

Wharncliffe blades offer outstanding cutting performance, and I’ve reviewed them many times. Backlocks (or lockbacks) are among the strongest folding knife mechanisms by design. The hand pressure is transferred directly through the choil and spine, meaning the force goes into the blade rather than the handle, preserving the mechanism even under hard use.

Despite its reduced size, the handle still allows a full four-finger grip. This is a true tour-de-force of design.

My Pingo features a thicker blade and, with its slipjoint mechanism, has proven to be a truly reliable everyday companion.

The Dragonfly, on the other hand, offers a more aggressive cutting geometry in a much more compact package.

The Wharncliffe blade really shines in use: only the tip makes initial contact, which helps preserve the edge from harsh impacts on hard surfaces such as ceramic plates. As a result, this small knife can even function as a surprisingly capable compact steak knife.

As my friend Jur once told me, “The older you get, the smaller the knives you’ll prefer.” Over time, I’ve come to realize just how true that is.

The Dragonfly in K390 is a remarkably refined combination. Ultra-compact and slim in the pocket, yet equipped with a blade that performs far beyond its size, it delivers outstanding cutting power and edge retention in a minimalist format.

Lightweight, discreet, and highly capable, it’s the kind of tool that quietly earns its place as a daily companion — equally suited to anyone who appreciates precision and performance in a compact form.

Spyderco Proficient FB36CFP — The Nasa Lamborghini Bushcrafter – Part 1

Article written by Nemo Sandman – Edited the 5th of November 2025.
All rights (pictures and text) reserved.

Have you ever wondered why so many Spyderco Sprint Runs seem to appear out of nowhere, featuring gorgeous carbon fiber handles and impressive CPM S90V blades?

It’s simple — Sal Glesser loves both materials.

For him, carbon fiber reflects his lifelong passion for motorsports, while S90V stands out as a stainless steel in a league of its own, combining high performance and outstanding reliability.

So, long story short:
Full Flat Grind + Carbon Fiber + S90V = Sal Glesser’s favorite combo!

And to quote my friend Spydercollector:

“When the Bushcraft fixed blade was first announced, Sal also planned to do a so-called NASA version; a version of the Bushcraft knife with all high-tech materials. I believe NASA is a protected name, but Endeavour still evokes the high-tech approach most people associate with the famous space agency. The Endeavour features a full flat grind S90V blade and full sculpted carbon fiber handles. It was a beautiful knife with a grip that had me looking around for stuff to cut.”

https://spydercollector.wordpress.com/tag/chris-claycomb-endeavour-prototype/

Here is the Proficient: it is designed by wilderness expert Chris Claycomb of Bushcraft UK, the Proficient functions perfectly with traditional bushcraft skills and cutting methods. Carefully contoured and polished to eliminate hot spots and ensure maximum comfort during prolonged use.

https://www.spyderco.com/catalog/details/FB36CF/Proficient-trade-/943

Bushcraft knives are defined by specific parameters — typically featuring blades between 4 and 6 inches. Spyderco’s Bushcraft model fits perfectly within that tradition: a 4-inch, full-tang blade with no handguard, purpose-built for control and versatility.

In true Bushcraft spirit, users generally favor high-carbon tool steels over stainless options, prioritizing edge retention and cutting performance rather than corrosion resistance. The O-1 tool steel used here, with its high carbon content, delivers excellent long-term sharpness while remaining easy to resharpen in the field.

Carried on the belt or strap in a leather sheath, this knife is blueprinted for wilderness chores — slicing, chopping, whittling, and processing game — all in the traditional Bushcraft style.

To quote Spyderco:
“The Spyderco Proficient takes the concept of the traditional “do-all” bushcraft knife and elevates it to new levels of performance with state-of-the-art materials and manufacturing methods. Designed by wilderness expert Chris Claycomb of Bushcraft UK, the Proficient functions perfectly with traditional bushcraft skills and cutting methods while offering superior durability, edge retention, cutting performance, and corrosion resistance
Instead of traditional carbon steel and an axe-like “Scandi” (Scandinavian) grind, the Proficient’s blade is crafted from vanadium-rich CPM®S90V particle-metallurgy stainless steel and boasts a full-flat grind for low-friction cutting performance.“

This concept of a stainless blade paired with a black polished handle has, ten years later, been fully embraced — a perfect example being the Casström No.10 Swedish Forest Knife in Black Micarta with a 14C28N flat grind.

I first discovered CPM S90V back when it was still known as CPM 420V, thanks to Darrel Ralph (RIP) and his beautiful Apogee folder. The blade was astonishingly wear-resistant — so much so that, without diamond abrasives, only a backstand could bring it from dull to sharp. It was a bear to sharpen then… and still is today.

The difference is, as end-line users, we now have easy access to industrial diamond tools, making steels like S90V finally practical to maintain at their full potential.


I have written a lot about S90V. This alloy has proven it can be tough enough as a stainless steel to be used in any all terrain tools; especially since it is available on Manly folders which got the reputation of using a very fine thin geometry on their blades.
Modern Bushcrafters (like the Benchmade Puukko) are focused on toughness with the use of the very tough CPM 3V.

What does CPM S90V bring to the table?

It’s incredibly wear-resistant.
This steel is notoriously hard to dull, even when cutting abrasive materials like brown cardboard loaded with silica. It keeps its edge far longer than most steels, making it ideal for demanding, real-world use.
Also the full flat grind is a must in a matter separator specialized in wood works. As much as I love Scandi Grind found on Woodlore clones (first designed by Ray Mears).
I have found that especially in the wonderful Spyderco Sprig full flat ground knives can be really efficient on hard wood.
(BTW when the writing appears in green: it is a link !! and I have tested them here.)

It’s stainless!
Even if you (like me) enjoy the patina that forms on a great carbon steel blade, there’s real peace of mind in using a reliable stainless steel — especially when working near water, in the rain, or by the sea.

The Sprig was an impressive tool in terms of pure geometry. Designed as a hunting and fishing knife, it was a real wood eater — a beaver of a blade, cutting deep and effortlessly.

Guess what? The Proficient shares the same profile, especially after a bit of convexing — which I’ll be covering soon in a second article.

So far, that contoured handle is an absolute delight to use, and I’ll be putting it to the test in the upcoming piece. While the old O1 Bushcrafter had enough heft for light chopping, the Proficient excels at powerful push cuts — a completely different experience.

Interestingly, the Proficient isn’t a big knife. Once sheathed, it can disappear into the front pocket of a pair of denim jeans — no need to let it dangle from a belt.
So what do we got ? Imagine the plateforme of the Bushcrafter (link) a solid companion, a reliable 4×4 and you just turn it into some Urus from Lamborghini: stellar alloy and lighter tougher handle.
The Proficient is Sal Glesser’s gambit — a bold move in a world where the bushcraft community traditionally favors carbon steel and natural wooden handles. This knife dares to break from that norm.

Of course, this jewel comes at a price, and most bushcrafters aren’t Wall Street sharks. They use Opinel, Mora, or at best a €100 fixed blade — unless they’re ready to splurge on an original Woodlore.

So, the “stealth wealth” of this NASA-grade bushcrafter isn’t for everyone.
It’s like a Lamborghini — not the most practical, but a statement of refined performance and engineering excellence.
Because in the end, real performance comes at a price.

The mighty Benchmade Adamas BM275FE-2 CPM – Cruwear for Flat Earth ? First glance at that Heavy Metal Hardcore Folder.

3 Comments

Here it is the Benchmade Adamas second generation with its CPM Cruwear heavy duty blade.
It has been almost 20 years since I have reviewed one of Benchmade hardchore (made for the Military) folder. The last one was the AFCK Axis in D2 and I even think it was not upload even if it was my EDC for two years. I loved the AFCKs because, well, Sal Glesser was involved in its design with Chris Caracci and Les de Asis and Bob Terzuola and I simply appreciate Sal Glesser’s way to invent and design “matter separators”.

But here it is “Tabula Rasa” as far as I am concern ! Go figure: no hole in the blade, but holes in the handle, a gifted designer which I’m going to discover named Shane Sibert who has also designed the Bushcrafter for Benchmade… and Clive Owen’s knife in Sin City.
His signature seems to be fuller on his blade.
“I started making knives in 1994 with the idea of creating blade ware that is simple, practical and efficient. I have been a full-time knifemaker since 2004. Keeping with the theme of practicality, I avoid large metal guards, bolsters and heavy pommels to keep the knives balanced and agile in the hand. Materials have been carefully selected to ensure optimal edge retention and low maintenance. Although the knives incorporate slim handle slabs to decrease unwanted bulk and weight, the handles contour the hand for a synergistic fit. I strive to hold myself to high quality and design standards and produce a knife that will invoke pride of ownership and at the same time perform the task that it was designed for with exceptional ease.”
(quoted from Arizona Customs Knives)

You can notice slabs and hole on the handle.
Actually for such a big knife the Adamas is not that big.
The first version was release in 2011 (you can see it here on Arizona Customs Knives) and was made of D2 the new version came ten years later and with its blade upgrade to CPM Cruwear.
This steel is known to be tough ! Less than CPM3V but with a better edge retention. The Cpm Cruwear Shaman was a big hit !
Here Benchmade has heat treated the CPM Cruwear to 63-65 HRC !
This is something I need to test as it is much harder than Spyderco HRC (61-62HRC) on their CPM Cruwear blades. (Sal tested his own blade at 61.1 HRC).

Cruwear Manix 2 – (63.2 – 63.7) HRC
Cruwear Military – 62.9 HRC
Cruwear Mule (re-release) – (62.1 -62.8) HRC
Cruwear Paramilitary 2 – (62 – 62.8) HRC
Cruwear Para 3 – 61.7 HRC
Cruwear Military – 61.1 HRC

At first touch, the Adamas oozes quality and delicate attention to details. The Olive Drab G10 slabs are wonderfully tappered on both ends and the jimping is done perfectly in my book, not as aggressive as G10 Manix for example. It is palm friendly even when closed. Well done. The holes in the handle help my thumb to index the tool.. There is no hot spots. The handle is totally open and easy to clean and check for debris. It is created as a workhorse which can get dirty but still reliable.
Of course this is an expensive knife with a MRSP at $280.00 but you can see where your money has gone. It is manufactured with love.
The blade is perfectly centered on mine and there is zero blade play in any direction.
I love the Axis Lock concept since its very first Henry&Williams BM710 release.
I have never had any issue with its Omega Spring. It is easy to use with one finger when the SPyderco Cage Ball Bearing needs two finger to work. The Axis Lock makes any knife as fast as automatics. I have never had any play on mine and I have been using them since their very very first release.
I won’t do batonning with the lock engaged like some youtubers seems to do until lock failure. For record, you can do batoning with an opinel…
But engaged lock (any lock) does not like to schoked and a beating can damage an disengaged any lock even a butterfly. Knowing how to use tools in the right situation should be mandatory before doing really stupid things on video and if anyone want to use a folder for batonning some wood (stupid millennial fashion as far as I am concern) just do it with no lock engaged or learn how to bring a better tool…

But once deployed, with just a gentle flick of the wrist — axis lock with heavy blade are just extraordinary easy to deplay— the blade is shown in all its power. I understand why some youtubers would like to shove it in concrete or in bricks…. I’m not certain they will be able to peel an apple in public with it but for that kind of task a Mini Adamas has been released with the same blade thickness…. Oooh well I’m not certain the thick Mini Adamas is made for fruits either. F<or that there is another tool too: the Kapara…
The Adamas offering a 0.14″ | 3.556mm thick blade, it is designed hardcore for hard chores for folders. How will it behave, that will be in our next article but that blade surely offers a lot of lateral strength.
For now it is just a very first glance.
All specs of the Adamas can be found on Benchmade here.
You can also notice on that picture its deep carry clip which can be a nice touch for such a big heavy folder. More on that later.
The action is smooth at the pivot but needs a little breaking at the lock release; nothing some nano oil can not fix.

This is a very beautiful folder which is very well balanced, its sweet point being just under the index finger when hold in hammer grip.
It is alive in my hands.
The axis lock makes it ambidextrous and you can notice on that picture the 3 points for adapting that clip or another three screw clip (not deep carry) if needed on both sides of the handle.

The blade handle ratio is almost to 1 with the Adamas compared to the Military C36 which is known for its long handle.
Of course the Adamas came very sharp out of the box, but not as sharp as I want. The blade is protected with cerakote coating Flat Earth colored which got excellent reputation in terms of tough protecting the CPM Cruwear from rusting. Cruwear can get a patina but it is not easy.
Here Benchmade and Shane Sibert have chosen to propose a stealthy look for the soldiers which need no blade reflection under the sun too.

It is also sold with a very nice sheath offering many carry options for soldiers and hunters alike.
The deep carry clip is perfect in term of retention and ease to retrieve the big and heavy knife.
Oh it is 183 grams (5,45 oz) which is really heavy. The liners are stainless steel not titanium. This is Heavy Metal !

As you can notice the Adamas is much thicker than the C35 Military and much heavier too. Sal Glesser wanted his military to be as light as possible as a soldier got already many heavy things to carry.
Benchmade has taken another direction. The Adamas is beefierand thicker. Actually it can also been more confortable for long usage. We will see…

Another beefy released was the Shaman which almost has the same handle length. The Adamas provides a lot of edge.

Here is my good old AFCK Axis. It was used with a lot of love as you can notice. Zero issue with the lock BTW.

Now it is time to give some work to that Adamas designed to “deliver unrivaled performance throughout hard-use applications”. The next step will involve certainly some sharpening and reprofiling…
More to come soon…. But for now on, it is a knife which makes me grin when I open and close it. Kuddos to Benchmade and Shane Sibert for bringing this second gen of the mighty Adamas.

NATIVE CHIEF™ REX 45 SPRINT RUN™ – C244GBORE – The Joker !

6 Comments

“It’s been a long road
Getting from there to here
It’s been a long time
But my time is finally near…”

Yes, it has been 22 years (since 1999) that we have been waiting for the Native Chief to be produced.

Sal Glesser said:

In 2008: “We only made one prototype. The model never went into production.”

In 2017: “The Native “Chief” has been on hold for some 15 – 20 years. I imagine we can get it to queue if there is demand. I’ll watch the thread. The Shaman is designed to be 3.5″ blade length which is legal in more places that the Chief’s 4.0″ blade.”

In 2018 “Working on the refinements for the 3rd prototype. We work on roughly 20-30 designs at any given time…. We’ll use a Golden back lock.”
Then…
“I’ve been carrying a “Chief prototype. A 20 year old “sal” design with modern “Eric” mods.” had written Sal Glesser in March 2019.

As shown on Eric Glesser video “Native Chief Breakdown”, the prototype looks a lot like the finale version.

Here is also a video from Wouter (Spydercollector) presenting the production sample:

Also, knowing the Vanilla version released in 2019, all made in their new facility in Golden Colorado Earth, was in S30V, waiting for a Sprint Run was mandatory in my case.
I got my eye on the Rex45 Chief before even to be able to get the Tree Rex Shaman. Rex45 seems to me a great steel for such a “toothpick”. Last year I had the chance to get a Tree Rex and my experience with that alloy made the wait of the Chief even longer.
You can read my thoughts about CPM REX45 here:

https://nemoknivesreview.com/2020/02/07/the-tree-rex-also-known-as-the-shaman-in-cpm-rex-45-and-dymondwood/

To quote Spyderco’s site:
“Crucible® CPM® REX® 45 is a super-high-speed particle metallurgy tool steel enriched with large volumes of cobalt, tungsten, molybdenum, and vanadium. Its high cobalt content increases the steel’s attainable hardness and enhances the positive properties of the steel’s other alloys. The addition of vanadium promotes the formation of vanadium carbides, which provide high wear resistance, fine grain size and increased toughness.“

CPM Rex45 is just great: no chipping, pleasant to keep ultra sharp with only some leather + compound stropping: a great super steel. Just be careful with its dust with 10% of toxic cobalt, better be safe than sorry.

OK, my Chief was expected for the first of April, hence the name “Joker”. The slim shade and the burnt orange color scales also inspired me… (Certainly not the Joachim’s or Jared’s crappy interpretations, much more Ledger and Bolland.)

Back to the knife: stretching in length the Native is a beautiful result. Since the Native model people were asking for a longer version and a shorter version, they have been heard.

Right out of the box, the Chief felt very angular: sharp edges on the scales, gritty G10, and a lot of hot spot on the choil/ricasso and the blade spine.
My Mandy City felt the exact opposite and it cost me a third of the Chief Price. So I was a little disappointed. It was not love at the first sight. Luckily , I know my Spyderco for a looooong loooong time and get my sandpaper ready.

I have send it under the tap to avoid any G10 dust which are really toxic for the lungs. Now the handle is suiting my taste.

The last experience I got with thick all-G10 construction knife in the Spyderco Family was the great Manix 2 Lockback (sold for 99 euros !) which was a great hard working folder.


The G10 slabs are much more thick than with the steel liners construction.
Quoting Sal:
“Actually Eric and Tom went over this model with the engineers for quite a while before making the decision to make it liner-less. We’ve done a lot of experimenting lately and you can see a lot in the many different designs and options. It surprises me that some would think to make decisions on values without any experience. if we screwed it up, we’ll fix it, but we don’t screw up often considering the many envelopes we’re willing to push.”

Compared to the Police:

You can compared thick G10 and thinG10+Liners.

As with the steel liner’s knives, there is zero flex and zero play, horizontal or vertical. It is like a vault. (My old Benchmade AFCK BM800HSS got titanium liners and flexes a lot.)
G10 is a really solid material. They even makes stealthy fixed knives with G10 blades… A steel liner could also bend and warp, not a thick G10 slab IMHO. Also the Cold Steel Recon folders are steel linerless and Cold Steel’s Recons are known for their sturdiness. I got an XL Recon and the lack of liner is really not an issue.
The blade, helped by two bronze phosphorous washers, chutes free when unlock which is very reliable and easy to learn to put back the knife in the pocket. It is done smoothly and fast.
It is a very secure way to close your knife.

Let’s not forget: a one hand opening knife needs to be a one hand closing knife. The best example is using a knife at the top of a ladder: you want to be able to get the knife back in the pocket easily and safely.

I’m not a huge fan of the hour glass clips founded on the Native 5 and the Delica/Endura/Paramillie/Para3. It has been immediately replaced mine with a Blade4sell small titanium clip.
Let’s do a family photo:

On the Shaman (“made to be a fairly heavy duty folder. Simple, but stout.” according to Sal), the Chief, the Native and the Lil’ Native my favorite clip is that last one.

The Native family is the no “hump” clan of the Spyderco Catalog.
The Chief is co signed by Eric and Sal.

Back to the Orange Chief, I was not really pleased also by its edge geometry. I felt it thick behind the edge. Even if the knife was razor sharp out of the box, it could not pass my plastic bottle test which consist in cutting the butt of a soda bottle by the center which is thicker.
The thin Manly City was able to do it right out of the box, as were able my Swayback, my PPT or even my Delica too for example… The champions being the Michael Walker and the Nilakka.
It is a matter of “deshouldering”, convexing the edge as always.

Diamonds are super steel best friends.

And now it is able to pass the test. 🙂
But let’s do it again for good measure.

Once thinned with diamonds, I usually strop it for a nice shining results. So far I need more elbow grease but it slowly get better and better.

Also the choil was very sharp to my taste. A little diamond filing and it was much more finger friendly.

So far, the Chief is a slim knife but destined to be very polyvalent. When the Shaman is very outdoors oriented, the Chief finds its place also in the kitchen.
It takes time to built a natural patina on Rex45 but it will come later after some fruits and hot meats.

The orange scales make it very table’s friendly too, despite its very pointy shape which could make sheeples nervous.

In a plate nothing force you to keep the edge perpendicular to the surface. I have found REX45 being hard to dull on plates anyway. It is a very easy going steel.

Another easy going steel is K390 found in the Police Model. You can see it is a tad longer than the Chief with also a thinner stock blade.

The Chief is elegant and certainly one of the most beautiful design in the Spyderco scuderia. Their backlock is so solid, the handle will break before it. Sal Glesser knows that making a longer version of the Native was not as simple as a sketch on a drawing board. You can watch the video at the end of this article about that.

The double signature, Eric and Sal.

THE TREE REX Part 2 – Beveling THE SPINE.

Leave a comment

The Tree Rex is certainly my favorite hard work folder from Spyderco. Sal Glesser has made a real beauty able to deliver a lot of power.
The handle is especially thicker and rounder than any other folders proposed by the Golden Company. The pseudo wooden slabs which can be rinsed in water with zero issues. (I have erased the smell with some alcohol solution) and the mighty blade made of a very lovely steel: REX45 got that “touch” of Speed Star aka M2HSS I have loved on Benchmade AFCKs and Nimravi. The steel is easy on leather and bites steady when whittling with control. The best wood chisels are made from M2HSS.

But they are some hot spots on the spine and on the choil. I use my thumb to pushcut in wood and a square spine is painful after a while.
Knowing the Rex45 is a 8% Cobalt steel, I have decided to send it in the wind and with some water to prevent dust. The very hard steel (66,5 HRC) was eventually rounded to my taste.

    Rounding the spine to a be less aggressive was done using 600 grint sand paper. Eventually I have used the sand paper to do some convexing.
    Soon a Jade stone will be tested for mirror finish on the edge.
