This is my full review and testing process, Rope, Cardboard and Wood. The process is to cut 5/8" Manila rope until 20 LBS is reached, then move on to cardboard and the wood cutting.

The knife was reprofiled to 15 DPS and finished at 400 Grit SIC.

1st up is the Rope

The knife made 1,100 slicing cuts on rope until 20 lbs of down force was reached. There wasn't any issues with the edge or the knife in general, had one small shiny spot on the edge after the rope cutting, the knife would still slice phone book paper after the rope cutting.








2nd was the Cardboard Stage.

The knife was resharpened before this stage back to hair whittling sharpness. I sliced 5,500 ft of cardboard, that's 1833 Yards or slightly over a mile of cardboard, there was zero edge damage after the cardboard and the knife would still slice Phone book paper after this stage. There wasn't any issues with the knife at all, lockup is still solid.






















Last was the Wood cutting Stage:

The knife wasn't sharpened before this stage, I made thick and thin cuts in wood and snapped the blade out sideways to stress the edge. There was zero edge damage or any other issues with the lockup and or blade play after the wood cutting. Noticed no additional dulling after this stage....













Conclusion:


The K2 performed far above my expectations, it was for the most part flawless other than that one small shiny spot on the edge during the rope cutting. Lockup remained solid, zero blade play and the edge retention was the best of any production blade I ever tested. Didn't notice any hot spots and the K2 fills the hand nicely.

The K2 can do some real work as was shown by cutting over a mile of cardboard then whittling wood without having to sharpen it so it could make an excellent field knife as that showed and the 1,100 cuts on the rope showed it would make an excellent hunting blade.

What does the shiny spot on the edge imply? A dull spot?

Fantastic test! It looks like the K2 can hand pretty much anything you throw at it like many of us knew it would.

Like a roll in the edge or a flat spot, could have been my fault, but I have to note it.

Awesome, I've admired the K2 design. I'd really like to get my hands on a Spyderco one at some point.

That is one huge heap of cardboard dude!

Well done there.

Great test! Thanks for sharing. We are truly living in the golden age of knives to get this kind of performance from a production blade. Very impressive!

Nice work Jim! Thanks for taking the time (and effort) to do these tests for our community!

Excellent review/test as usual.

Good job on this knife Farid and Sal.

I am very much surprised by how well the steel did in your test. Best ever is pretty strong coming from you.

Jim thank you for testing the K2, keep in touch my friend.
Farid

Forgot to ask and assume this is the case. The K2 came to you with .020 behind the edge or is this something you did?

Off topic question. Who did you have do your Manix 110V regrind?

CPM 10V is no joke and it's really at the top of the scale of what Crucible states what steels are suitable for knives.

A production knife in CPM 10V @ 63 HRC, yes it's going to be right at the top performance wise...

Yes it was .018 - .020 out of the box...

Chris Berry can do the regrind of Big Chris Custom Knives.

Excellent thanks for the quick reply.

You have a PM also :)

Not a single chip. Go figure. It's like Spyderco knows how to make knives for an intended use, or something. :)

I think it's clear by Spyderco's long and storied history that they have no idea what they're doing.

:p

Thanks for the informative review, Jim. I would love to see a review like this completed on all of the new designs. We'll done, sir, and thanks for adding the nice pics too!

A lot of that is sharpening. :D

Also I am sure that Spyderco and Farid did a lot of R&D before settling on the blade and edge geometry at the end hardness.

.018 - .020" behind the edge, 15 DPS and 63 HRC, that's going to be stable for a general use blade. :)

Hi Ankerson!

And THX Much for your comprehensive review and detailed info. :spyder:

For all those who wondered about the comparison, here it is!

Outstanding. Planning on adding one of these to the stable. Nice review.
