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!

QSP PENGUIN PLUS – Titanium and 20CV blade. Revenge of the Emperor penguin ?

Leave a comment

My first Penguin’s encounter occurred thanks to Massdrop which offered the QSP Penguin for 26 dollars.
This was a bargain for a lovely well made lil’ folder (review linked)

As I was looking for a big not threatening folder, I was studying different wharncliff designs or sheepfoot blades for that matter.
Ending my quest with that little Spyderco wonder in the previous review: the Dragonfly.
But back to the QSP birdy pictured here with a Spydiechef:

But my need for a more longer blade (especially in the kitchen) was still on and then I have found that QS130XL-B – QSP Penguin Plus Titane.
Same specs as my beloved D2 Blue Denim Micarta QSP but everything is different 😉 because this is the Penguin PLUS with:
A longer blade. Blade length 8,6 cm.Blade thickness 3,5 mm.
A flipper.
A titanium handle
A 20CV DLC longer blade.
Length closed 11,4 cm.
Ceramic ball bearing..
Lockbar insert.
Titanium clip.

Weight 127g.

The price was 7 times the price of my first Penguin on thebestknives.eu in Vesoul, France. Great bargain and great service.

And here it is:

It is razor sharp right out of the box. Well balanced and all the contour are chanfered. It is a very nice tool knife.
There is a serious heft in this blade.
The action is not stellar because of the detent on the coating but the knife fires with ease thanks to a great detent and an heavy blade.
The integral lock is a little on the sticky side but nothing dramatic.
The whole package is a flat easy to carry medium folder.



But that thumb stumb as to go.
Why ?
Because there is no choil and if you miss your thumstud firing (instead of using the flipper) chance are high to get your thumb encountering the razor edge of the blade.
So it has to go.

It was easily done with two torxes.
Now I got a little hole but it suits me.
I have done the same treatment 23 years ago with Benchmade BM710 this kind of treatment assures you to get a little longer working blade eventually as the studs loves to get in the way.

The tip looks like a sailor or electrician knife and seems strong enough for many knife tasks. In the wharncliffe blade design the point is in contact with cutting board or the plate and gthis one is pointy enough to draw my blood while writing that review…
Well well now it is time for the real testing which will bring another review soon enough.
This is a beautiful knife with a strong straight long blade which disappears in the pocket with its deep carry wired clip. That titanium clip retention is very good BTW.
The handle is made of gorgeous bronze titanium which gives a nice patina look to it and eventually a very vintage toolish low profile look. This is destined to be a hard used folder used in middle of brass and copper. Its flipper is even providing a security guard preventing the hand to slip forward. Instinctively they are many grips and many usages to be considered for a solid folder.
And in terms of edge retention, CPM-20CV is one of the best stainless steel to be found nowadays linked here. Not the strongest (like CPM-3V) but certainly one of the best balanced.

So this is really a nice knife to EDC to put to its paces.

Pictured here with a Ed Schempp Bowie.

And a Swayback.

And for the next step a de shouldering of the edge is mandatory.
Diamonds work great.

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

5 Comments

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.

Folders, Review

SC60GPGY Spyderco Massad Ayoob Sprint Run — The Pistol Folder is back but for who ?

2 Comments

This Spyderco folder, designed by Massad Ayoob, the well-known firearms instructor, was conceived as a self-defense folding knife. A concept I struggle with. In my view, almost any tool with an edge—or even a screwdriver—can be used similarly. The rest is largely marketing, especially in a country with a deeply rooted personal weapons culture.

Not for me.
But what if I’m wrong?

Massad Ayoob is a respected authority, LEO (law enforcement officer), firearms instructor, and writer on defensive use of force, including edged weapons. For over four decades, he has taught defensive firearms and knife programs and has frequently served as an expert witness in court cases involving such tools.

(Adapted from his bio: Backwoods Home Magazine)

He directed the Lethal Force Institute (LFI) in Concord, New Hampshire from 1981 to 2009, and now leads the Massad Ayoob Group (MAG).

So should I even be reviewing a self-defense knife when I’ve already stated elsewhere that, in my humble opinion, knife self-defense is the worst possible use of a blade?

This is less of an issue for professionals—law enforcement or military personnel—who may be forced to face knife attacks. But for civilians? Learning to defend oneself with a blade should remain an absolute last resort in a situation that likely could have been avoided through awareness and mobility.

As a design, I’ve always liked the C60, especially its ergonomics—not as a weapon, but as a cutting tool. It works exceptionally well for kitchen and general use. In fact, it was once one of my favorite “baguette openers” in the folding knife world, particularly in its serrated version.

Even knowing it was marketed with a design intent focused on deep penetration between ribs and vital organs, I’ve never been impressed by such narratives. Many everyday tools—chisels, screwdrivers, crowbars—can be used for harm. Intent matters more than geometry.

Spyderco, of course, is no stranger to this “self-defense niche”: Canis, Matriarch, Carahawk, P’Kal, Chinook, Civilian, Yojimbo…

Blast from the past.

In the 1990s, I had the opportunity to be among the first European reviewers of Master of Defense knives. Jim Watson, James Keating, Massad Ayoob, Graciela Casillas, and Michael Keating were all involved in the project.

Ayoob contributed the MoD Razorback, a fixed blade designed primarily for rapid deployment in reverse grip from a kydex sheath. He even timed his draws to demonstrate speed. I liked the concept, but it was clearly optimized for thrusting rather than cutting.

The same philosophy can be found in the C60: more oriented toward penetration than slicing, especially compared to something like the Yojimbo 2, which balances both.

The Razorback prototype is in the center, while Michael Janich’s Tempest appears at bottom right, featuring his Filipino grip concept.

On the C60 Sprint Run, Michael Janich wrote:

“From a utilitarian standpoint, the negative blade angle increases cutting power and leverage… I also strongly encourage you to consider a Schempp Bowie…”

Benchmade BM275 Adamas part 2: Reprofiling – From Puff Daddy to Daddy Cool !

3 Comments

It’s time to de-shoulder that Benchmade Adamas‘s edge and to convex it a little to my own taste.
My tools are Spyderco Stuff 2 with diamonds, Fallkniven DC4 and leather strop.

First thing I will do is remove the stud which are in the way. I have found/learned that the hard way just by testing the angle, I have scratched them.

Two T6 torxs are necessary. One on each side.

Cerakote protection is found even inside the stub hole. In fact I was really tempted to remove it for good as the Adamas is so easy to open and close just by manipulating the Axis Lock button. But sometimes I need to be able to open it one hand and slowly too…

Next step is to protect each side of the blade, as I don’t want cerakote to be scratched… yet. I use white gaffer for that.

Slowly the edge is convexed and thinned. CPM Cruwear at 64 HRC is hard and diamonds are mandatory. It is a slow process all made by free hand.

Leather stropping is apply next. Again this is made slowly.

Soon this is a razorblade popping hairs just in one caress.

The Soda Bottle Butt Test was not passed in my previous test.
This is the reason I have decided to thin the edge of the Adamas in the first place.
Now it goes steady in like in butter.

The center of the butt is much thicker and harder to pass as the bottom can collapse. This is really my geometry test and many famous knives were not able to pass it.

The Adamas is now much better in terms of pushcutting and its steel (CPM Cruwear) is perfect for a thinner edge.
The stud has been put back and the big folder is ready !
