Joe, I guess my biggest question is not so much about edge holding as it is in how fine an edge can BG42 take in relation to the edge that ATS-34 can take. As far as edge holding, I've just about given up on that with any steel. I have not up to this point been able to discern a <u>practical</u> difference in edge holding between, say, ATS-34 (Benchmade), ATS-55 (Spyderco), and M2 (BM), but the M2 takes a much finer edge, and is easier to obtain. Therefore it is my favored.
For me, the vaunted 440V takes almost as fine an edge as 1095 or M2, but doesn't hold that edge nearly as good as the M2, and not much better than the 1095 in my REKAT UNK. At this point, in my uses, BM's ATS-34 or the ATS-55 of my Spydie Standard hold a better usable edge than Spydie's 440V. So my experience so far has pretty much been that ATS-34 is about as good as it gets.
However, looking at the composition of the two, and reading the steel FAQ and reading threads, one would be led to believe that the BG42 should hold its edge as well as the ATS-34, yet take a keener edge due to the Vanadium. But, I'm a very inexperienced amateur, and really want to hear other people's <u>experience</u> with the two.
