SPYDERCO SQUEAK Part IV – The Micro SlipIt as the only travel knife.

Choosing a travel folder is easy for me — I own quite a few knives of various lengths dedicated to that purpose.
Traveling from France to the UK, however, means avoiding any locking blade and any edge longer than 3 inches (76 mm).

Models like the UKPKMetro, UrbanChaparral Slipjoint, The Roadie, the Manly Wasp, or even the Couteaux des Sorgues or any small Swiss Army Knife, would all fit the bill.

For the record the non locking mechanism of the SlipIts is reviewed in this review here.

But this time, I’ve decided to take the Squeak designed by Sal Glesser. The Titanium/Elmax Sprint Run Jewel. Easy to pocket, One Hand opening are my choice. Usuaully I use a UKPK from Heinie for my UK trips.
This time, it will be the Squeak Deluxe. This micro-folder has been a constant companion in my pocket since 2017, and it’s perfectly watch-pocket friendly — but as my only knife for a road trip? That’s the real question.

I don’t know about you, but my uses for a knife when traveling abroad are many — from cutting labels to sharing a piece of cake.

The first thing I ask from a blade is that it stays very, very low-profile.
deep-carry clip is mandatory in that regard. However, the Squeak’s stock clip isn’t exactly discreet, so I swapped it for a MicroJimbo clip — the same one used on the Lil’ Native — which is noticeably shorter.

Frankly, this shorter clip should come standard on all SlipIt models from the factory!

I often use my EDC knives right on the plate. Eating with a sharp blade is non-negotiable — and most of the time, my wife ends up borrowing mine, so it goes back and forth throughout the meal.

Of course, ceramic plates aren’t exactly a razor edge’s best friends. They can sharpen a blade in spots, but mostly they’ll dull it fast.

For food prep or eating on a plate, my favorite blade shape is the Wharncliffe, since only the tip makes contact with the hard ceramic surface. The MicroJimbo would have been perfect for that — if only it weren’t a locking knife. Honestly, I’d love to see a Wharncliffe SlipIt someday!

For now, the Squeak brings a bit of belly and that razor-sharp Elmax edge. It truly shines with pizza — that perfect mix of soft top and hard crust demands a blade that cuts deep and steady.

I didn’t bring any sharpening stone to touch up the edge, but I found that mostly the tip was the part coming into contact with the ceramic.
With longer blades, I usually tilt the knife slightly to avoid any 90° cuts against the plate. But with the Squeak, I just went at my pizza like a hungry wolf.

The result? A bit of dulling — maybe 1 mm toward the tip — but nothing I actually noticed during the trip.
I sometimes straighten a rolled edge on a mug’s rim or a sink edge, but not this time. I didn’t bother. Elmax isn’t brittle, so there was no real concern anyway.

The tip needs to stay razor sharp, since I also use it to open plastic bags, while I use the edge near the pivot for cutting labels. Despite the dulling, I couldn’t feel any loss of performance on plastic.

Using a short blade naturally means a bit more sawing motion, or sometimes two slashes for one cut — but with the Squeak, that was no issue at all.

Its biggest challenge might have been scones, but with those, I just think twice and cut once!
Even slicing a lemon for tea worked perfectly — I simply rolled the fruit on the board while cutting through it.

All those mundane tasks only proved how essential the Squeak was as our sole cutting tool during our five-day road trip.
It handled every meal — cutting bread for toast, slicing soda bread leaves — and never once did I feel underknived.
The Squeak performed flawlessly in every task, and above all, it was an absolute pleasure to carry and use.

So, does size matter?
In this case, the Squeak has clearly proven itself as both a great travel companion and a perfect EDC for countries that are cautious about knife laws.

Spyderco CALY™ 3.5 – C144CFPE Caly 3.5 ZDP – Part II – Back To The Convex edge !

Disclaimer: The Spyderco Triangle Sharpmaker Diamond Rods Set of 2 – 204D was provided by Golden, along with the Caly 3.5. This article is the perfect opportunity to put them to the test.
The Sharpmaker is my own.

In the parcel from Golden were also two sets of rods: the 204CBN Cubic Boron Nitride rods and the 204D Diamond rods. Since my Caly 3.5 needed some convexing, it was time to see what these rods could do.

But you know, I’m a freehand sharpening guy. I don’t like being locked into fixed angles. I prefer to adjust pressure and movement based on what I feel directly from the blade against the rod. That’s why I’ve never been too fond of “systems” that take control away from your hands.

For me, sharpening should stay super simple, and—most importantly—adaptable. If I’m in the wild, far from the workbench, I still want to be able to bring an edge back with nothing more than a rod, a stone, or even something improvised.

That’s where the Spyderco Sharpmaker is different. It’s a system, yes, but it doesn’t dictate the process. It allows me to sharpen by feel, with freedom, and still gives me the precision I want.

Exactly — and that’s one of those clever little details only Spyderco would think of.

On the back of the Sharpmaker base, you’ve got two horizontal grooves that let you lay the rods flat. In that configuration, the tool basically transforms into a bench stone. With the diamond rods mounted this way, it works like a compact, portable diamond sharpening stone, letting you go full freehand.

So you get both options: the guided 30°/40° setup if you want consistency, and the freehand mode if you prefer to feel the steel, control pressure, and chase your own convex. That versatility is what makes the Sharpmaker more than “just a system.”

The gaffer tape trick is smart: it saves you from accidental slips while keeping the grind line safe. And yes, the 204D diamonds are hungry — they bite into ZDP-189 without hesitation, which also means they’ll scratch anything that touches them. But like you said, a working knife will earn its scars.

Polishing can always bring back some scratchless shine, but what really matters is how the geometry evolves: a little convexing, a thinner edge, and suddenly the Caly 3.5 stops being just elegant — it becomes a laser.

That’s exactly where your knife starts to become yours.

The convexing not only boosts cutting performance but also gives the edge that organic flow — you can see it in the way the bevel catches the light. It’s no longer a factory grind; it’s a living edge shaped by your own hand. It makes the knife more precious.

And by rounding the spine and softening the jimping, you’re turning what could feel harsh into something smoother, almost like a river stone. It transforms the Caly from safe queen into a companion you actually want to use every day, without hotspots or distractions.

Most people underestimate how quickly diamond or CBN rods load up, and how much that affects sharpening efficiency.

Clay stone (terre de Sommières, or even a simple pottery stone) is excellent because it’s mildly abrasive: it lifts out the embedded metal without scratching or damaging the surface of the rods, and it works faster than detergents or erasers.

It’s also in the spirit of my philosophy: keep it simple, practical, field-ready. No fancy cleaners, just a tried-and-true trick that works every time.

Dry chestnut is fibrous and can grab onto a thicker bevel, so the fact that your convexed ZDP-189 now glides “like a razor through butter” is a strong demonstration that the edge mod really paid off.

Convexing changes everything. Once the edge’s shoulders are rounded, the edge stops fighting the wood. No more wedging, just a clean, controlled push cut — like sliding through butter, even in stubborn chestnut.

That’s where ZDP-189 really shines. Most steels would give up at this geometry, folding or rolling. But at 65 HRC, ZDP holds steady. You get the sharpness of a razor without the fragility.

And the Caly 3.5? On paper, it’s a gentleman’s knife. In hand, convexed and sharp, it’s a wolf in disguise. A refined tool that thrives on real work, not just resting pretty in a pocket.
Wood tells one part of the story, but plastic will reveal another — especially the stubborn bottom of a bottle. That’s where I’ll see if this convexed ZDP-189 edge can truly glide without wedging. I’ll update this post as soon as I get the chance to put it through that test.

Spyderco Microjimbo Sprint Run CPM-15V – The Evil Baby Brown Benjamin

Created by Michael Janich, the MicroJimbo takes the iconic Yojimbo 2 design but in a smaller form, making it more legally and practically usable for everyday carry (EDC).
This piece is a true jewel. With an MSRP of $300, it ranks among the most expensive Spydercos when measured by cost per millimeter of edge: just 57 mm. That’s a scale of value I may have to start considering. On the Microjimbo in 15V, for example, each millimeter of edge comes to $5.26, whereas on an Endura in VG10 it’s only $1.56 per millimeter.

Of course, CPM 15V is costly, and two signatures on the blade mean royalties. It’s a jewel, yes—but also a gem in its own right.
No disclaimer on this one, as it was bought by myself at Lamnia in Finland for 237 euros. Great service and it was delivered in France 5 days later.

Action wise, the detent on mine is quite strong, with no lock stick, and the blade drops freely back into the handle. This little folder practically oozes quality.

Compared to my Yojimbo 2, the Microjimbo features a full flat–ground blade with a distal taper—very reminiscent of the first Yojimbo in that regard but with full-flat-ground Wharncliffe style blade, roughly 2.45 inches long.

It is made of Made from CPM-15V, a cold-work tool steel with nearly 15% vanadium, prized for insane wear resistance and edge retention.
The blade is heat-treated using a protocol developed by Shawn Houston, further enhancing its performance with a HRC of 65 (more or less but that’s a lot !).

Ambidextrous, tip-up carry only for the MJ and its reversible deep-pocket short wire clip.

It is equipped with Spyderco’s reliable Compression Lock.

The 3.7 mm thick, stonewashed blade is a beauty—short, sharp, and full of character. The edges aren’t perfectly even toward the tip, but that doesn’t bother me; sooner or later it will be convexed anyway.
After just a couple of passes on leather, the Microjimbo was already delivering a crisp, razor-sharp edge, effortlessly shaving arm hair. And for once with CPM-15V, I was pleasantly surprised at how well the steel responded to stropping.

In my CPM-15V family this little folder is not the one to underestimate.
That blade shape as proven to be incredibly powerful.
This knife feels like Lotus Seven equipped with a V8.

The Microjimbo 15V, with its self-defense pedigree, actually falls into the same MBC category as the Lil’ Temperance. With such a compact edge, it’s more of a last-ditch option—a tool that could still deter a threat. It won’t reach vital organs, but it could sever an artery. That said, knives remain one of the worst possible choices for self-defense in my book.
Knives are ambush/backstabbing weapons.

Another last-ditch, highly capable small folder is the Chaparral Serrated. Its serrations can be extremely painful—an advantage in self-defense situations when you need to break a hold and get away.


Remember: 1 – Run, 2 – Hide, 3 – Fight.
Fighting should always be your last option!

For three times the price of a Metropolitan, you get the same edge length but in a heavier package. Once in hand, it feels remarkably secure—despite having neither guard nor choil—almost like holding a small fixed blade.

Another comparaison shot: the Lil Native convexed by Jan Dirk feels much smaller and stubby than the Microjimbo. But on the picture there is no real difference. Both are reliable lil’big knives with strong blades and strong locks.

There’s no jimping on the handle or the blade, yet indexing the knife is effortless. You always know exactly where the edge is, allowing for precise, controlled cuts.
That G10 definitely leans toward the pocket-shredder side.

I prefer my G10 with a smoother finish, so I used 400-grit sandpaper to tone it down—taking care to avoid inhaling the hazardous G10 dust.

I’m able to carry the Microjimbo in my watch pocket. I appreciate the strong detent—it keeps the blade securely closed while in my pocket. However, because it’s so strong, it’s difficult to open with any finger other than the thumb. No easy Spyderflick on this one.

The Microjimbo isn’t out of place on the kitchen cutting board. In fact, this will likely be its main battlefield, as I use my pocket knives extensively in the kitchen. I do need to be careful, though—its pointed tip tends to catch the flesh with a predator-like hunger.

Once razor-sharp, I haven’t been able to dull any of my CPM-15V blades so far, even after cutting cardboard and other abrasive materials. I’m glad to carry such a compact yet robust folder as I continue to explore this remarkable alloy.

Michael Janich has clearly done his homework on this little knife. Designing smaller blades is always tricky, and this one is a pure gem. The choice of a full-flat-ground blade is fully justified by the placement of the Spyderhole, and the geometry remains uncompromised.

I’m looking forward to putting this little knife through its paces.

SPYDERCO LIL’ TEMPERANCE™ 3 LIGHTWEIGHT K390 -C69PBL3K390 -Part 2 – Draw Shorty !

First things first: I needed to “de-shoulder” the edge, and K390 proved its reputation as a hard steel. I noticed it again when rounding the spine a bit — those vanadium carbides really make sanding a challenge. Then again, sanding has always been something of a signature for me, especially when shaping convex edges. With 2% cobalt in the mix, keeping the blade clean is essential to avoid stains or rust.

Now, onto the fun part! When you get a new knife, what matters most is how it fits into your life: what makes you smile, how people react to it, and how it feels to carry and draw it from your pocket. The joy of using a good tool should always be a pleasant experience.

The Lil’ Temp 3 is stubby, with a distinctly modern folding knife look. Its blue handle helps it appear approachable — a friendly tool rather than a “ninja weapon.”

One of the biggest drawbacks of the original Lil’ Temp back in 2001 was its clip. That thick, rigid piece of steel with four screws made getting the knife in and out of your pocket more difficult than it needed to be.

The LT3 solves this with its spoon clip, which is easy to tune. Following Sal’s advice, the knife is now effortless to retrieve from the pocket — a huge improvement. The LT3’s handle design also helps: I carry the folder tip-up, and the beak at the end of the handle, combined with the FRN traction patterns, makes the knife practically jump into my hand. Drawing it is effortless, even while sitting in a car.

The squarish handle also is a big plus: it helps indexing the knife instinctively : You know where is your edge immediately.
So, it is very safe and easy to draw it and open it, do the cut and then close it and pu it back in the pocket. You do that without thinking. Muscles memory…
It is a huge plus for a working knife’s user to be able to use the LT3 and close it and put it away back in the pocket in a breeze.
This is also really enjoyable, and coming from many great Spyderco Designs like the Military 2 or the Sage 5 or the Para 3, it is noticeable how nice that LT3 LW is in getting into action.
To sum up, it is really pleasant !

For exemple my lovely Lionsteel Nano is not the easiest to bring into action but it is forgiven as it is considered as a “Lady & Gentleman” folder.

But for a workhorse they are other specifications. Safety and reliability in putting in action your knife is mandatory.

FRN once molded in scales can propose high tech shapes and pattern designed by Sal Glesser which are enhancing the ergos even with wet hands.

The LT3 is one of the most confortable folder i have ever grip. The handle is thick, filling my hand’s palm and ready to be squeezed for hard cuts. The thick blade spine is asking to be pushed into materials.
That’s why my first mission was in the kitchen with tomatoes and lemons…. 😉

After a first cut into lime and avocados the blade was already getting its nice patina. K390 is deadly serious about getting stained and it is a good thing as that patina will protect the naked steel from pitting. I just wipe it clean after a rinse under the tap and check that the pivot to be well oiled.
This is exactly the opposite I do with the Sage 5 Salt ! I’m careless wth those Salt folders. This Sage is smooth like butter even without any oiled pivot. Magnacut and the Sage pivot design turn it like into a knife you can keep dirty and forget in the sink.
Not the LT3.
As strong as its is, its Achilles heel will always been proper care and maintenance. But serious users know how to take care of their tools. And maintenance is also part of the fun of owning good knives. The patina on the K390 blade will always show proudly that your knife is a user not a safe queen.

There is also the solution to cut cheese to keep naturally some grease your blade.
Those two cuts here has been made with the LT3. As you can notice those are clean push cuts. the geometry is that great.
Actually, in the kitchen, or preparing the meal in a camp, that LT3 is at home. That 4mm thick spine is not an obstacle as the blade is tall.

This is one of the things I love in my Cold Steel Voyager or Recon 1 XL: thick high blade but thin geometry. Thhose got much longer blades than the LT3 !

But the C69PBL3K390 does not act like a wedge on fruits like avocado or apple.
But once you turn it against harder material like plastic, you can apply a lot of force ! The handle is so comfy you can use it like a fixed blade. This stubby folder turns into one of the most solid “matter separator” ever made by Spyderco. It feels much more solid than their flagship, the Military and much confortable than their Shaman ! Go figure !
Let’s not forget they all got the same designer but, after 25 years of in house refinement, the LT3 is not a small contender. I even feel the LT3 could be the personal answer from Sal to the Spyderco Techno !
3 inches of pure K390 performance.

Now thickness is always an important factor in performance.
The UKPK is uncanny sharp with its thin blade. But it is designed for more mundane and delicate works not for being used hard in a construction site, for example.
The LT3 plays in the same field as the Tenacious. (The last sprint run in CPM-M4 is really perfect for dirty hard chores.)

Both knives are choil less, with full flat ground blades, and they got an open back construction handle, easy to check and clean.
The Tenacious is a little bit longer offering a great blade/handle ratio.
But the LT3 got a stouter blade and a much better action/ compression lock.
And also a much much confortable handle.

About blade ratio, let’s quote Sal:

Many of our blades are designed to a blade length legality. The Delica is a perfect example. The blade length is 3.0″ which is acceptable in many places for legal reasons and for social concerns. The handle designed to the blade length is just not large enough for many of the people that use knives as tools. So I made the choice to give the handle extra length for safety and control. 

In my opinion, blade to handle ratios are an “eye” thing, which is fine, but I prefer to design with the bend towards function and safety. “A scalpel would not perform better if the handle were smaller or the blade longer”.

“Choil less” does not mean that your index finger is in jeopardy !
In case the ultra strong compression lock would fail or get disengaged…
There is no choil but there is a kick ! So your index finger is relatively safe !

Wait a minue! That LT3 Lightweight’s handle reminds the handle of the now discontinued Spyderco Vagabond. (The FB12 Vagabond was a compact fixed blade designed for on-the-go food preparation, such as picnics or packed lunches.)

See?

Same “beak” at the pommel too !

Thick handle and thick 3 inches blade on both.

Same designer again. 😉
I told you the LT3 was a “wandering rōnin” 😉

So once the LT3 has jumped in your hand, it is really sheeple friendly with all its gentle curves and nice handle color. It looks like a puppy of a bigger knife, a cute knife actually. That’s also a big plus for a low profile working tool.
If someone working in a ranch uses a LT3, it won’t raise any eyebrows. It is as threatening as a screwdriver. Nowadays this is a big plus to own a low profile knife. Also when in sheeple hands, the LT3 is able to deliver. Yesterday, the family kept borrowing my knife, even to cut the crust of the pie for the Grand Ma ! This would not happen with my beautiful pointy Military 2 (Even my pointy UKPK was seen by them as a weapon able to pierce some armor…) ! The Lil’Temperance is just seen as a high tech folding tool, easy to control and put on “safe” and this is just what we ask when children are running around the table.

“The game never ends when your whole world depends
On the turn of a friendly card” Alan Parson Project.

The Temperance tarot card represents balance, moderation, and harmony. It encourages patience and finding the right mix in life – whether in emotions, relationships or work. It is a sign of inner peace and divine timing.
And this is exactly what the Lil Temperance3 Lightweight is oozing from its synthetic pores right at the moment you hold it.

Six months with the Golden Child – Spyderco -C94GCBL- UK PENKNIFE™ COBALT BLUE G-10 CPM® SPY27® – The Part 2

I have had the chance to buy that UKPK in G10 for 100 euros in January 2025.
Since, it has been my “go to the city” favorite folder.

Sometimes replaced by the Roadie XL for a lower profile or Dredd my Urban in S90V made in Maniago and exclusive to Heinie in the UK.


The UKPK is remarkably versatile, proving itself even in woodworking. Its strong, reliable mechanism keeps it ready for anything — all while remaining fully within legal limits. Stripping vines, carving rods, scraping, cutting — it handles everything with ease. The spring “lock” never falters, and the finger choil adds an extra layer of passive safety, even if it’s rarely needed.

Its thin yet strong CPM SPY27 blade is a true joy to use on wood. In this domain, the UKPK stands out as one of Spyderco’s best hidden gems across all categories made in Golden. And if I ever had to defend myself against an animal, I believe it would perform every bit as well as the legendary Calypso (all the story here).

The tip has seen plenty of use, and all I can say is that Spyderco’s in-house SPY27 steel is extremely forgiving. You can push it hard with no damage to the edge. I’ve compared it with many of my favorite wood-cutting knives — including some specialized for woodworking — and it performs impressively in the same league.

One way I now measure the value of a pocket knife is by the pleasure I get from using it. The UKPK easily ranks among the top on my list. Strong, thin, and precise, it excels as a true “matter separator,” handling everything from everyday tasks to more demanding jobs like scraping paint.

There’s also a distinct joy in keeping the edge razor-sharp, and SPY27 has become my new favorite for that. Achieving a razor edge is a breeze. Being in the AEL-B class, it’s even easier to work on than Magnacut and is extremely leather-stropping friendly. After just a quick session on leather, SPY27 regained that legendary crisp edge — and it’s such a pleasure to use!

Hairs are flying and the convexed home made edge is shining like a mirror.
This is really part of the joy to use leather strops on a steel.

So it is a joy just to strop it again and again just to maintain this razor edge.

Then for forced push cuts, the geometry of the UKPK is just a killer.
It goes deep like a thin Opinel blade can go.

To keep the knife sharp, I’ve mostly relied on leather stropping, with occasional touch-ups on white ceramic, even after cutting cardboard, plastic, acidic food, and hard wood. The UKPK in SPY27 is a winner, offering a significant boost in edge retention and versatility. Maintaining its vorpal edge is even easier and more enjoyable than with the excellent Magnacut or LC200N versions.

It’s no wonder this steel has earned such a special place in my heart.

And I was not able to get any chipping or edge bending in six months.
It gives an hint about the high quality of the inhouse heat treatment on that inhouse steel.

Used in the plate, the SPY27’s core refused to be damaged:
no pitting, no rust, no stain. No damage on the plate ceramic too.
It a gourmet companion and a wonderful carnivorous friend.

In the kitchen, geometry-wise, the UKPK can compete with the best — for example, the Patrick Bonetta Kitchen Warrior. The G10 version is also a visual delight. I never felt “under-knifed” with my Urban, but the UKPK could easily be my one and only Spyderco. A three-inch, legal, high-performance sharp blade is a must-have for EDC, and such knives are surprisingly rare.

This is 100% Sal Glesser design. This Golden-made gem is the all-terrain pocket knife my grandfather would have dreamed of!
Hence its name The Golden Child. 😉

For an alternative you can now get The Metropolitan. Its little brother.

Spyderco Chaparral C152SGY – As a main travelling knife.

For a two-week road trip in Italy, the serrated Chaparral was my only knife. Sal Glesser’s Chaparral has been studied many times on this blog, but lately, the serrated version has become a central part of my rotation.

Why is this knife such a great traveling companion?

Friendly FRN handle: The grey FRN offers excellent grip, even with wet hands, making it comfortable and reliable in a variety of conditions.

Blade length: At less than 3 inches (71 mm), it’s easily accepted as a pocket knife. The serrations effectively add about 25 % more cutting edge, boosting performance without increasing size.

Flat and thin: Its slim profile allows it to comfortably fit in a watch pocket.

Sturdy mechanism: The hidden pin ensures zero vertical play, providing a rock-solid feel.

So this little big knife was my main cutting gear for two weeks.

I was able to open it in restaurant without to be noticed and replace the dull silverware provided.
The serrated Chap is a folding steak knife by essence.

Its thin blade is making the cuts accurate even on delicate cream croissant shared with a coffee.

One of the challenge for such a thin blade is the famous hard cheese found in Emilia-Romagna: the Parmigiano Reggiano.


Normally, Parmigiano is not “cut” — a traditional leaf-shaped short knife is stuck into it and breaks off large chunks like a wedge. That approach wasn’t a problem for the thin CTS-XHP blade of the Chaparral. It dug in deeply and, with a slight torsion, fragmented the cheese effortlessly.

Hard sausages in Tuscany can be made from deer or doe or even boar.
Again, bring a thing serrated edge to the board and it will be a success.

Pizza can be a challenge. You want to cut through all the layers without dulling the edge on the plate. Serrated edges do not dull easily in the plate. And even some knives encountered provide serrations at the end of the edge like this one:

Here the Chap near a friend’s Captain which has been used to deal with mozzarella.

It feels good to be not the only Spyderco in the village.

After two weeks with the Chaparral, I never felt “under-knifed.” It performed reliably in all conditions — rain, seashore, and forest — and remained socially unobtrusive. Its cutting power, thanks to the thin, hard CTS-XHP blade, proved that a pocket-sized chainsaw can be an essential part of any traveling kit.

After two weeks of use, the Chaparral showed no rust issues, no bent serrations, and no gritty mechanism. I simply rinsed it under the tap and let it dry in my pocket.

Even now, I don’t feel any need to resharpen the blade — the serrations are extremely difficult to dull. For a travel folder, I can confidently say: the Chaparral comes highly recommended!

If you want to see some spectacular moments from my two-week Italian road trip, I’ve released four video postcards on YouTube, all filmed and edited on the same iPhone 14 Pro that provided the photos for this article.

GETTING A CONVEX EDGE WITH THE CPM-15V BLADE OF THE HOULAHOULA PARA3 LIGHTWEIGHT PART 2.

Since the first try of convexing the Para 3, it is time now to reach the same level of de-shouldering as on my Sage 5 Salt.

My goal here isn’t to touch the edge itself, but to smooth the border between the flat of the blade and the edge angle. This allows me to maintain the edge primarily on leather while reducing drag when cutting hard materials like plastic or wood.

The equipment I used was again the Spyderco Double Stuff 2, focusing mainly on the diamond side. I experimented with gentle, round strokes on the flat diamond stone instead of always moving in the same direction — it seems to remove metal much faster.

For aesthetics, I plan to follow up with white ceramic or jade stones to approach a mirror finish, similar to the Sage 5. Magnacut responds beautifully to polishing, whereas CPM-15V doesn’t particularly care.

The use of gaffer helps preventing any deep scratches on the blade finish.
It works great. The black dust is metal removed by the diamonds.
I do that outside in the wind. I don’t want to breath that dust.

Eventually this second round has gone so smoothly (compared to the first one linked at the start of this review) that i was on the verge to work on the Military 2.

Remember Sal saying:
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.

The comparison between the Sage 5 Salt and the Para 3 continues. In short: the Sage 5 has superior geometry thanks to its high 3 mm FFG blade, while the Para 3 features a sturdier blade, a thinner point, and is overall lighter (no steel liners).

It’s really your choice — both are highly capable and complement each other, coming from the same design mind. Shawn Houston even notes that the Para 3 carries “that Delica vibe.”

I’m impressed by the Sage 5’s exceptionally smooth action — one of the best among Spyderco’s compression lock knives. I love both knives. These days, the Sage Salt rides with me, but while both won’t let you down, the smooth Sage is more fidget-friendly. Both are great, but the Sage 5 is simply less popular… 😉

For another fistful of minutes – De-shouldering the Spyderco Sage Salt Part 2

Let’s go back to the same process but adding 15 minutes more can be a game changer in term of geometry. But let’s be clear this is typically the Pareto law which says: “The Pareto principle states that for many outcomes, roughly 80% of consequences come from 20% of causes.”
It means that in 15minutes + this new 15 minutes it is not the most efficient as 80% of the job was done during the 6 first minutes last time.
But those added fistful of minutes are a little bonus to even the bevels.

As you can notice I have concentrated my thinning process mainly on widing the bevel.

10 minutes later, I got a more even larger bevel which should go shining after some leather stropping.

On another fistful of minutes, I will work on the tip but I like to keep some material here.
Now I’m basically dealing with a flat grind with a convex edge at the end.
In Japanese a convex grind is also called a hamaguri grind. Literally this means: clam. This name comes from the convex way the side of the shell moves to the end. Exactly like the full convex edge. A full convex grind is sometimes also called an appleseed grind. Again because of the pointy tip of the seed of an apple.( I’m a fan of  アップルシードa Japanese manga series written and illustrated by Masamune Shirow.)
But for now it is much than satisfying in terms of whittling and dealing with hard maetrail to cut.
The edge goes deep in every push cuts and the high FFG blade five a lot of control for powerful results.

So far my initial impression are confirmed: the Sage 5 Salt is a keeper and another 3 inches blade length Spyderco to rule them all like the Delica 4, the Native 5 or the Para 3 or even the UKPK ! All are Sal Glesser’s children (The Para 3 paternity is shared with Eric !)


It is perfect in all aspects – sharp thin blade, centered, strong detent compared to the Military 2, no blade play, suuuper smooth.
The Sage5 is the best implementation of a compression lock I have ever had… Perfect tolerances and no lock stick.


The open-backed construction allows easy cleaning. This Sage 5 is really asking to be used and, thanks to its yellow handle, retrieved even on the forest or ocean floor. Really a must have 3 inches knife for all occasions.
And I’m a huge fan of the Native 5 and the Para3. But this Sage 5 seems to lead the pack.

SAGE™ 5 LIGHTWEIGHT SALT® – C123YL – The Magnacut Amphibian EDC –

First of all, thank you to Guillaume Xais who has convinced me to try the Sage 5 Salt. I have found a deal under 200 euros.
In the past, I have owned some Sage(s) from the Sage 2 to the Sage 4 actually.
You still can find the reviewss by clicking the links.
The Sage 2 was a Sebenza killer when all the crave was about Christopher Reeves Integral Lock and titanium slabs.
The Sage 3 was the Blue Brother.
The Sage 4 was a masterpiece with its Front Lock and titanium Bolster never reviewed because too much a jewel of a knife.

I wasn’t particularly interested in the Sage 5 Compression Lock, and even less in the Sage 5 Lightweight. Yet both the Sage 5 G10 and Lightweight versions proved so popular and well-regarded that Spyderco expanded the lineup into Maxamet, SPY27, REX 121, Magnacut, and CPM-M4 (thanks to Guillaume for the editing).

With the vanilla S30V, the Sage 5 was offered in six different alloys — some of the most impressive in terms of performance — demonstrating just how versatile and capable this design can be.
 “The Sage 5 Lightweight has also proven itself to be a perfect platform for showcasing the elite properties of high-performance blade steels.”

For the record the Sage Series has traditionally expressed the same iconic design with different lock mechanisms, paying homage to the innovative designers who created them. Also Spyderco donates approximately 5% of sales of the Sage line to the National Alzheimer’s Association Denver, Colorado Chapter.
(A Sage 6 is soon coming with a button/compression lock as found on the Smock.)
So I have asked to Guillaume in the Spyderco Fan Club France, why should I invest in a Sage 5 Salt Lightweight in the first place ?

(Picture by Guillaume Xais – instagram Spydigex_knives)

“Its action, like any self-respecting Sage LW, is dazzling!
This yellow contrasts with the hardware, the clip, and the deep black of the liners, like a Black Mamba face… I love it!
My first Magnacut, by the way… I fish and am quite often at the seaside, it will complement my Ukpk salt (which is also very good).
My favorites, however, remain the 2 and 4, true works of art!

For me, it does everything better than a Para3: handling, fluidity, less fragile tip, less tactical image, more rewarding feel of the FRN… there’s no comparison (from my point of view, of course).
Add to that the Taichung Quality and Magna’versatility… they’re worth it, right?

I was convinced !

First impressions: there’s some real heft to this lightweight — thanks to the full liners. I love it. The blade is perfectly centered, and the lock doesn’t stick.

The detent is impressively strong, almost magnetic — stronger than the detents on my recent Para 3 and Military 2. Go figure! And the action is smooth as oily butter. Classic, perfect Taichung craftsmanship.

The FRN pattern is hard, grippy and catchy I even got some issue to put in my pocket.
It the same issue I had with my Chaparral Lightweight.


A passage under the sandpaper would be perhaps mandatory ? Let’s see what Papa Sal would advice in my case of protecting my pockets:
“You can lessen the tension on the clip as an easy solution. Some sand the scales bit.” Sal in the Forums.

Some gaffer to protect the black screws when using sandpaper.
Then cleaned under the tap and it’s good to go.

Well… it is so compact it can eventually be carried inside the pocket watch.
But Sal was right like always, bending the clip a little has completely changed the way it clipped and for the better.

The metal hardware is all black certainly PVD coated.  “Like all Salt Series folders, the clip, liners, and all handle hardware are also crafted from marine-grade materials.” said Spyderco.
And Guillaume is right, the contrast between the black and yellow is an eye candy.

I have found a little hot spot on the choil which I felt under my index finger. Nothing a little diamond file won’t eliminate in a matter of minutes.

Now let’s compare it to the Para3 Lightweight.

The Para3 is a really light package because there is almost no liner.

64 grams.

78 grams for the Sage 5 with its nested steel liners

The FRN is smoother on the Para3 as it is not the same pattern.
Being a Salt the Sage 5 is destined to be used with wet hands.

The Sage 5 has a thinner 3 mm blade, and the chamfered edges on its spine are just stunning — smooth under the thumb and a true Taichung signature. Even the Spyderhole is gently finished.

A major plus for whittling is how easily my left-hand thumb finds a comfortable spot on the blade spine. With the Para 3, the thumb doesn’t have a proper ramp parallel to the cut. On the Sage 5, the parabolic spine of the leaf-shaped bladelets the thumb push comfortably in the middle of the spine, which makes a real difference during whittling.

Same blade length, but a different spine shape. The Para 3’s Spyderhole is especially suited for use with gloves.

Is the Sage more of a civilian EDC and the Para 3 more tactical? Not entirely certain. The Sage feels more solid in the hand and has more heft, while the Para 3 feels like a light, quick-reaction tool, and the Sage 5 is an all-terrain EDC.

The Sage handle is more compact and can be carried in the watch pocket, thanks to its grippy FRN and strong clip.

Grip is essential when working around water or with wet hands. The Para 3 is gentler on pocket edges, while the Sage out of the box can be a pocket shredder. Following Sal Glesser’s advice, I flexed the clip slightly for lighter retention — now it’s perfect.

Next, let’s take a look at the Sage’s geometry straight out of the box.

I was able to cut through the plastic without having de-shouldered the edge yet. It will be done in the next chapters. For the record, I was not able to get a clean cut with the factory geometry of my new Para3 and Military2 in CPM 15V.


So this blade has excellent geometry right out of the box: this is really impressive ! Without any touchup of the factory edge it goes deep in any material, soft or hard.

The Sage 5 Salt is a pure Sal Glesser design with its iconic leaf-shaped blade. Fun fact: the letters S‑A‑G‑E appear in order in his name!

This great folder is made in Taichung, Taiwan, renowned for its exquisite manufacturing and quality control. The blade is chamfered, and the jimping is soft under the thumb, making it a joy to handle.

Ultimately, this is a Highlander knife“In the end, there can be only one.” The Sage 5 Salt feels like a Spyderco to rule them all — the only one I’d ever need in terms of portability, reliability, and performance.


Purely stainless from blade to screws, it is a true all terrain tool. I mean, you won’t need another knife as this one is totally impervious to salt water and boast that CPM Magnacut blade known for its great performance: “a revolutionary particle metallurgy steel that offers an exceptional balance of edge retention, toughness, and the extreme corrosion resistance.” It is true when properly heat treated and with the best geometry.
(Again all those green marks are links to previous review or sources of this review.)


Polishing the Sage’s edge on a leather strap — aka stropping — removes the final imperfections, leaving an even razor-sharp edge. Magnacut, in particular, responds beautifully to leather stropping.

With the Vigtig and the Nano. I managed to get these three knives for under €200: the Sage 5 at €194, the Vigtig at €130, and the Nano at €192.

This means that, as of March 2025, CPM Magnacut knives can be found for as low as €130 — a good deal, though it may not last. The UKPK in CPM Magnacut should be in a similar price range, which I’m looking forward to.


So far, first impressions are excellent! The yellow handle makes it feel less threatening — more like an everyday tool than a “ninja mall weapon,” which is a definite plus these days.

It’s also ready for kitchen use, thanks to a strong edge that isn’t afraid of ceramic plates. Magnacut takes a razor-sharp edge easily with just a bit of ceramic and leather work. No need for diamond paste like on the mighty CPM 15V.


The amphibious Sage 5 is a perfect traveling companion — from mountain rivers to the ocean. It delivers impressive cutting power for its size, biting into hard wood effortlessly. The blade spine is very comfortable for push cuts, making it a reliable all-terrain tool.

It’s a dream knife for fishermen and woodcrafters, capable of accompanying you in virtually any environment.
So far the Spyderco Salt serie is enlarged to very nice plateforms with Military flavours and civilian purposes.


First impressions of the Sage 5 are excellent — in terms of action, geometry, and ergonomics. This is a great EDC that’s fearlessly corrosion-resistant.

Thanks to Guillaume for the tip!
Now time to convex it !

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

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.
