I expected M2 perform better than T15 ... a puzzling surprise. PM M2 will be better than tested but would lose its fine carbide attribute - since MC in PM steels are 1+um in size, while ingot M2 carbide dia around .75-1.0um.
Hello Luong from a cruise ship anchored at the island of Lifou. The T_15 is looking impressive in your tests so far. What are your preliminary thoughts on its edge retention with your heat treat 3.0?
Happy New Year and Cruise to You! Agreed T15 earned itself a confidence feeling in hands and good test results. I didn't perform any endurance test for it yet. Projected edge retention 80-90% to 10V, above M4, way above V4E. Any suggestions on kind of endurance tests (and edge geometry)?
@@BluntCutMetalWorks Shaving a pig is always a test of a knife's edge retention. However, not always a realistic test. I guess a good substitute would be a natural fibre rope like sisal or hemp.
Shaving pigs (or boars) would be fun to try - just need opportunities :) I've plenty of 1/2" dia sisal rope. I think, sisal is dirtier then hemp/manila rope. Anyway, I will touch up the T15 edge with DMT F+E then video the cutting - of course, I will try to catch ~when the edge no longer slice phonebook paper cleanly. If not too tired, will keep cutting until it tear printer paper (just for comparison to test by Cedric & Ada Gear and Outdoors). Will 10x speed through boring parts.
I didn't expect t15 to do so good, especially at that hardness. M2 would probably do better with PM.

@@BluntCutMetalWorks Sounds good. Looking forward to seeing the results.
