CRKT M-40


I’ve always thought CRKT’s production of Kit Carson’s M-16 knife design was genius. Of course much of that had to do with Carson’s design for a sleek and effective flipper knife.  Combine those ideas with the Deadbolt® Locking Mechanism designed by Flavio Ikoma and the IKBS™ Ball Bearing Pivot System and you get the hot, new for 2020 CRKT M40-02.

Open CRKT M-40, M40-2
The M-40 from the company everyone likes to call Cricket  or CRKT 

Here are some specs:
  • Blade Length      2.9 inches
  • Closed Length   3.9 inches
  • Overall Length   6.875 inches
  • Weight 3.3 oz
  • Blade Steel         1.4116  This martensitic stainless steel contains 0.45-0.5% carbon and 14.6% chromium.  But the secret sauce is 0.1-0.25% vanadium.  Vanadium forms very small very hard carbides that give the steel its strength and wear resistance.  It is an older steel alloy and might be thought of as similar in performance to 420HC steel made famous by Buck Knives.


I’m not a steel junkie.  Properly harden and temper a good steel and you’ll get better performance than most of us will ever need.  At least, I will.  Most of my knives are working blades.

The Deadbolt® Locking Mechanism is simple to use one handed and prevents your fingers from ever getting between the closing blade and the handle.

The lock is reported to be the strongest lock on the market, of course as Bill Clinton testified, it all depends on definitions.  Still I’m impressed with it and we’re going to see this lock on a lot of knives.

I liked the way flipper flies the blade open and the pattern of alternating parallel line checking really jazzes up the glass reinforced nylon handle.  The two steel liners illustrate my favorite CRKT virtue: their engineering and construction makes for a hell of good knife.

The clip is reversible and it comes set up for tip up right hand carry.  I remember pleading with CRKT at a SHOT Show 15 years ago to move to tip up and reversible clips.  They didn’t listen to me, but thank God they listened to someone!  The tanto seems to fit the pattern better than a spear point.

It feels good in my hand, looks good and I think it’s a great little knife.  I think you will like it for an EDC.

The suggested retail price is $140.00.  You can get yours at https://www.crkt.com/m40-02.html.

Serious weight: CRKT Seismic



Just got my hands on CRKT’s new Seismic with the ‘Deadbolt Lock’ developed by Flavio Ikoma.  It’s a beast!  It weighs in at 6.3 ounces with a 5.5 inch handle holding a 4 inch blade.  I like knives with slightly over sized handles.  You need a big handle to hold and use a big blade.

Flavio Ikoma has become one of Brazil’s top knife designers.  Growing up he was fascinated with the varieties of Japanese swords.  Encouraged by his father and having access to the tools and materials in his father’s shop, he made edges.  This interest spurred him to learn metallurgy, work with other knife makers and become a knife innovator.

The Seismic sports his IKBS ball bearing system as well as what has been described at the strongest lock on the market, the Deadbolt.  There are always a lot of claims of the strongest lock and they seem to depend on the test methodology.  Still, the Seismic locks up with one hell of click.

To release the lock you press the knurled ring around the pivot.  This pushes a large bowtie shaped bar of metal out the back of the knife and unlocks the blade.  Impressive!

Here are some more stats:
The 0.6 inches thick handle is G10 overlaid on a sketalized metal frame that.  The G-10 has a grippy feel to it, almost enough to give you the fingernails-on-chalk-boards feeling.  (Assuming you know about chalk boards.)

The blade steel is a ground slab of 1.4116 stainless steel 0.15 inches thick.  This steel is reportedly used in Swiss Army knives.  The blade is a drop point with a high shoulder, flat grind.  A shallow false edge decorates the blade.  The sweeping edge reminds me ever so slightly of a skinner.

This steel is reported to have a RHc of 55-57.  While many consider that too low to retain an edge, let me remind you of three things:
  • That hardness resharpens quickly with simple stones;
  • Steels in this hardness range tend to bend instead of snap when misused; 
  • Ernie Emerson once said a knife with a bent blade is still a knife, a knife with a broken blade is junk.

What’s in 1.4116 steel?  The composition is relatively simple, 0.45% carbon, 14.7% chromium, a sprinkle of vanadium at 0.17% and a smattering of elements common to modern steel manufacturing.  Reports from the field suggest 1.4116 steel shows good corrosion resistance.  That’s important to me as I’m a bit careless with my tools.
