turn on CC and enable english as the language in the settings.

The Russians sure know how to heat treat and grind the geometry very well. Yanhook heat treatment. i think the gentlemens name in English would be Denis Frolov if im not mistaken. He also does the heat treatment of the Crocotool and various other small knives and tools by Evgeny Polukhin. these small tools of various super steels at high hrc's as well as 440c with cryo. Kizer also picked it up and made it in s35vn (but in kizers heat treatment only). https://www.bladehq.com/item--Kizer-Crocotool-Stainless-Steel--84341

i know not everyone likes youtube or even cutting tests, but most people will have to admit this is fascinating of what a steel can achieve in these types of tests. it took several days and a huge bag of cut rope in the end. more than anything he's ever tested prior.

They also did one in N690 too. which showed excellent results as well

again turn on Closed Captioning and change settings to English.

better than their previous HT, but not better than the s110v HT.

im not sure when English sub's will be available. but ill try an post when he has them. youtubes auto translate kinda sucks on this one.



check out the geometry on that one at the end of the vid (in HD).
 
Cultrotrech is certainly a grail knife maker for me, his practices are top notch and he makes a knife for beauty and function equally.

The URS
the unique design, the blade grind and the heat treatment.... cuts more than anything before it.

That's their custom vs production HT. It's even harder I believe.

So, why would knife companies not improve or tweak their heat treats to get the performance SVARN II offers? This literally doubles the performance of S110V and M390.

How? Aren't heat treats just precisely baking and cooling the blades? How does "baking" them correctly cost more money once you get the process dialed in?

Its more complicated. Time is money. It takes alot more time to do it. Requires Temps to more exact. Enough time to soak. Then requires liquid nitrogen and multiple tempers with Ln2.

You can't do 1200 knives 1 at a time or a few at a time to make sure they all are properly heat treated. So yea it's considerably more expensive to provide a proper heat treatment for many knives. Not to mention grinding them to near zero grind precisely.

I wish it was fast easy and cheap. Basic heat treatment is fairly easy, but the more complicated and higher in the hrc range can get a bit more difficult. Also running such a thing in mass production would be fairly difficult imho.
 
If you were so inclined, you could call or email Peter's heat treatment and ask how much it would cost to heat treatment 1200 thin ground blades to 64hrc with triple ln2 tempers. Maybe have one done and send the knife out to get cut tested by outpost 76 on yt and see his results match this.

Dennis F. Didn't go into specifics of his heat treatment other than multiple Ln2 cycles. alot of his knives are cold forged also. Which is very interesting technique of making knives in the 20th century.
