Thanks Jim. I just ordered a Ultimate Hunter fir myself, my first Cold Steel knife in quite a while but when a company goes out and does something right, im all about supporting it. Im a big fan of xhp even at the hardness we get from most production knives and I'm pretty excited to try it out at its sweet spot. Have you ever tried s35vn from microtech? I was pretty impressed with it compared to few other brands I tried and would like to see your opinion of it.
Thank you and take care.

1st CS folder for me in 20 years. Thanks for the tip Jim.
Cool, glad you are liking it.
Nice.
Haven't tried it yet.
Thanks again for the testing Ankerson!:thumbup: The list is getting quite long!
Thanks.

I'm surprised this statement didn't receive more attention. A lot of people seem to avoid crk like the plague because of the hrc. Any proof in the pudding Ankerson? Have you tested crk s35vn within the last two years? I'm curious because I haven't noticed it to under cut other similar steel from other manufacturers.

I have a 25 in the list, coarse edge section.

Oh yes, I see that. Not too bad for a steel with a "terrible" heat treat. I'm curious to see how an insingo would do in the lineup since I carry one a lot and I think it's thinner behind the edge.

I'd be happy to send mine if you're interested. ^

I saw one or two of them, they are very close to the same thickness behind the edge, the 25 I have is .021" and that was after reprofiling it to 15 DPS.
My impression is that the Sebenze 25 and the Inkosi use a heavier blade geometry -- a relaxed, large-wheel concave blade grind. Usually, when you reprofile to a more acute angle, you widen the edge shoulders, but you still gain because the edge angle is more acute. Edge angle and thickness behind the edge have to be considered in tandem because to a large extent they affect each other.
Because Jim standardizes the tested edge angle to 30 degrees inclusive, the data he shows on the shoulder width is especially valuable.

The 25 has an interesting blade grind, I had a long conversation with Anne Reeve about it, well more than one actually.
Part was for the article I wrote and the other part was for my own information as I would be testing it.
The knife does cut extremely well from my experience and it's not really that thick, actually thinner than a Spyderco Military, both spine thickness and behind the edge.

Thanks for the response, I would have never guessed that about the 25.

It's going to be somewhat cheaper and easier to get, work with etc.
They can be very close in performance depending on the actual HT, geometry etc.
Interesting, Do any steels handle less than 30 degrees inclusive with no damage when used somewhat hard on cardboard and such? I'm debating buying a wicked edge for the super steels but I don't know if i would reasonably want to take them to less than 30 degrees or not. Apologize for all the questions.
I would like to explain some things.
S110V holds some advantage against S90V as far as edge holding is concerned when it is at 63HRC (S90V@60-61 as a reference). Now, please bear in mind that this will be only in a 100% highly abrasive media environment. In a mix of daily cutting tasks the gap will be barely noticeable.
In my mind S110V it is NOT a quantum leap forward, as it is i.e. S125V, even at 62.
What it is always true is that S110V and S90V at aforementioned hardness levels will score different toughness, clearly enough in favor of the latter.
This introduces another matter, which answers to your post.
If your tasks involve harsh media as ones mentioned to which I would add opening blisters, and some small impact or side load (albeit small ones), you will be able to face them with S90V using smaller edge angles and TBE (thickness behind the edge): in a word a more proficient geometry. This in your own cutting environment would lead S90V to eventually outgun S110V.
You mentioned 30 inclusive. I would not set -in your meant usage- less than 40 inclusive on S110V/S125V. And 36 inclusive on S90V. Unless going very fine with grits, like 10k Naniwa Chosera, but it would prove far less proficient in your cutting target.
Facts are that these very high alloyed/very high carbon and very high carbide content SS do require some edge thickness to support the high volume of carbides.
Unless you know that they'll be used in a very well defined environment, which excludes side load, impacts etc., which I do know being the case for Phil's customers.
Ha! A funny thought just occurred to me. If it weren't for the laws of physics, where steels and heat treats that result in higher hardness and wear resistance, also lower toughness and increase brittleness, BladeForums would be a boring place, it it existed at all. Lol

What's even more funny is that you can bring i.e. Elmax @63 and have the very peak of toughness for that steel, higher than at 62.
Now, could you tell me with what heat treat and why? Law of physics are funny indeed
