The scrapyard scrapivor features a high carbon steel (SR-101) blade that is heat treated to 60-62HRC.
are you expecting a knife to whittle, cook food and edc? If so, you'll end up with a knife that isn't particularly suited to any of those tasks.
Why do you want 1095 past 60? It does get quite brittle and is easy to chip out. At 58-59, it is VERY easy to sharpen and is relatively resistant to chip outs. Push it much past that and you risk a lot more chipping.
What is your reason for wanting a super hard tool steel?
Do you have any experience with that, or are you jus parroting something you've heard?
I've used a 1095 fixed blade at 65rc and had no chipping whatsoever. Matter of fact, it rolled when I cut cardboard instead of chipped. Two slides down a ceramic and it was good to go again. Really hard 1095 is awesome.
Check out custom makers to get your fix.
It isn't the difficulty in tempering 1095 to above 60 hrc (hell powder steels are far more difficult and expensive), it's the practical use that gets in the way.
1095 above 60 hrc is very hard and is more prone to chipping which is something that no one wants in a knife. In abuse or even rare normal circumstances (cardboard can sometimes have hard materials inside) they don't want a knife to chip.
A knife edge failure should never be a chip, it is far far more preferable to roll. A chip requires grinding out the blade and re profiling at times. A roll requires simply bending the knife edge back.
By tempering it to below 60 hrc, the 1095 will roll before chipping.
My custom Alan Davis custom, performed well but compared to S30v, it did not keep a fine edge as long but it did keep a serviceable edge for just about the same time.
Hello
Is there any manufacturer selling 1095 knives hardened in the sixties ?
What kind of performance one could expect on a thin FFG blade made from it for regular edc, kitchen tasks and wood whitling ?
Thanx
1095 is still 1095 at 55 HRC or 65 HRC, yes it will perform better at 65 than at 55, but it still won't compare to the high alloy steels because the alloy content just isn't there.
Now back in the 70's when the steel choices of production knives being what they where things were indeed different, things are much different these days.
That said, finding a maker that will take 1095 to that range isn't all that easy in general and there are other steel choices if that's what one wants.
1095 is 1095 however it behaves differently under different hardness levels, or heat treatment from my basic understanding.
I don't think it is difficult to find someone to hit that type of hardness, it's just the unwillingness of the smith to work with 1095 to that range when there are dozens of steels which can outperform it at lower HRC, for example M390 can far pass 1095 in edge retention.
Now that I reread the OP. 1095= terrible kitchen duty steel. I've used 1095, and stopped doing so immediately. Anything mildly acidic will rust 1095 unless you constantly wipe it clean.
