were the edges still sharp when you ranked them or was it just a kind of cut untill it shaves thing? i dont know how many points it takes to get a knife through rope is all. im curious how a duller utility edge would hold up in each steel compared to a razor sharp edge
yeah im dumb and really tired, i finally figured that out five minutes after i posted that... moving accross country does that i guess. i think there are different kinds of edge holding. and edge stability. also abrasion resistance. but at least this test proves one thing. some steels just dont hold a shaving edge as long as othersHe did the testing till a specific downward pressure was reached.

Jim has also stated that the results would change just by giving knives a toothier edge. I think the knives for this test were finished to 6000 grit.
What knife was tested in vg-10? I would think it would have ranked higher
Has anyone tested AEB-L steels? I've heard that they can be hardened to 63+ and has very fine grain structures.
What knife was tested in vg-10? I would think it would have ranked higher
higher than n690
is there a reason like, higher hrc, for n690 out cutting vg-10??????
I have been on the fence about the Cruwear Mili, but your enthusiasm is pushing me to try it. From the charts, its edge retention is just below S30V, but if it is up there with M4, I am in for sure.Jim, I know this has been expensive. Even when knives are loaned to you. Let me know if you get over in this direction and I'll give you a very modest donation, plus whatever knife you want to test. The Cruwear mule if you don't want to wait for the Millie. It might help Sal sell some when people see how it performs.My prediction is group two.

Hello Joe. Why exactly does this happen?CPM M4 loses some to most of what corrosion resistance it has when run maxed out, but so do most steels.

Hello Joe. Why exactly does this happen?
Well, even at S30V levels that would be nothing to be ashamed of. I predict it will outperform S30V in all attributes except corrosion resistance naturally. It likes to stay sharp if it's ran up around where the mule was ran ( rc 62).
I'm not making any bets about it outperforming CPM M4. That's great stuff especially when it's at rc 62 or better. When pushed to max hardness it gets near S90V. cpm m4 loses some to most of what corrosion resistance it has when run maxed out, but so do most steels.

I'm not really able to explain like a metallurgist or engineer or even a good knifemaker who understands heat treat can. I can guess that more of the chrome is used making carbides and there is less free chrome available for corrosion resistance. I hope one of our metallurgists reads this and answers because I could stand a little learning on this subject as well.
I do know that some steels, 154cm for example, can temper at two different temp cycles. High temper, and low temper. look here at the heat treat response and see the huge differences in tempering temperatures. http://www.crucible.com/PDFs/\DataSheets2010\ds154cmv12010.pdf It affects the steel attributes 1) wear 2) toughness, and 3) corrosion resistance as well as final hardness.
Explanations from someone more qualified than me would be very helpful. I don't like the idea of me or anyone else guessing or giving incorrect information here.
I have heard 154cm described as acting like a high speed steel. The Similar BG42 ( vanadium added to 154cm) is a stainless high speed bearing steel, the stainless version of M50. ( here is some stuff about M50 http://www.suppliersonline.com/propertypages/M50.asp
Sorry I can't be of much use here.
