Spyderco Yojimbo2 C85GM4P2 CPM-M4 The Jade Warrior.

This is a bud of an article about the BladeHQ exclusive Yojimbo2.

At least there is picture.

Story will come later in multiple update.

I have reviewed the Michael Janich’s Yojimbo2 many time here.
And I have been waiting for a tougher alloy for a long time: CPM-M4 is one of my favorite steel.

Why ? Because it’s take a razor sharp edge and keeps it, it’s a tougher than stainless steel super steel and its edge stability is better: no chipping or warping in my uses. Of course it will get stained but that is the part of his multiple charms. This is a steel used in blade competitions and Gayle Bradley is a fan of it.

The Yojimbo2 design asked for a very thin point and a stronger, tougher steel. M4 is a must if you want to use it (like myself) in everyday chores… hard !!
Because such great ergos ask for hard working.

Compared to my previous YO2, the closing sound “TICK” got a much higher pitch than my S90V version. I had noticed that kind of higher pitch on another super tool steel: Maxamet.

Does it mean the steel is harder ? Will see.

So stay tuned!

I have changed the OEM clip for this one.


It’s a shortest deep carry clip.

The Para 3 in Maxamet got the same high pitch TICK.

Dirty blade ready for some chores.
Both knives are excellent EDC. The Yo2 offers really powerful cuts on wood.
A word which comes back a lot with my Yo2 review is “power”. The heft of the saber ground hollow blade and the confortable thick spine is a call for pushcuts and “very light” chopping. You will see what I mean in a few photographies…

Deshouldering and starting to get a thinner edge. The factory edge is excellent though.

“Ghost” and “Jade” together: same materials.

The handle lengths are different just because one is standing on its clip.

Push cuts are easy.

This is the kind of “very light” chopping cuts which are made in blink of an eye.
The Yo2 is a great trimmer. The edge bites deep and the straight edge won’t let go.

It’s very efficient !

M4 steel erases any fear of breaking the thin tip easily but I do respect too much my knife to try any lateral forcing. At least I’m no afraid to use that blade tip hard !

Rinsing and cleaning the blade in a spring stream. No real patina so far but soon it will come. M4 get darker in a slow way on my experience: no hurry !
But that Jade handle goes so well with natural environments…

There is a lot of charm in the Yo2: the heavy blade smooth action, the straight edge power and the great ergos ! Nobody seems to notice it while used in a restaurant, the Jade helps a lot to make it less a weapon and more a tool.

Military C36PIN CPM M4 Exclusive Run — Ghost in the Machine

For a funny reason I give name to knives I keep. It gives them more personality. For a strange reason all my C36 Military got name starting with G like Glesser.
My Military Sprintrun CPM Cruewear is “Gandalf” because of its grey handle.
My new Military with Natural G10 (or Jade G-10) and CPM M4 blade will be name Ghost. It’s an exclusive run for Blade HQ.

This is the first time I got the chance to handle the new version: no spacer, bigger lanyard hole, bigger screws… My first Millie “Glesser”, back in 1996 was already a new version with CPM440V (S60V) and the three screws clip. 21 years later here is what I consider the apogee in this design: a blade alloy I really love and a “light” construction.
Gandalf and Ghost weight almost the same: 124g versus 123g on my cooking electronic scale. This is a light package with a lot of cutting power.
I also love the fact that the Jade handle makes it very sheeple friendly and less “military”.

Since I have reviewed the M390 CF version and the Titanium handle version.

Now I have really convexed the grind on Gandalf for wood working.
But I wonder how it will compare to CPM M4 on Ghost.
It will be the subject of another review.
