I recently got my first blade in CPM-10V and have been very impressed with it, after some searching I can't really find much info on comparisons between the top tier of super steels, as in the steels production companies won't/don't work with. What I know so far is that CPM-10V = A11 = K294, the stainless version is of course more rust resistant but loses some toughness and edge holding which is CPM-S110V = K390. But how do these compare to some of the other steels as far as edge holding and toughness (enough toughness for say a 4-5" fixed blade at around 3/16 stock, maybe a little thinner, probably wouldn't be doing any batoning). Hopefully Phil Wilson or Ankerson can comment. Steels I'd like to hear you're comparison/experiences with: CPM-10V K294 K390 CPM-S110V CPM-15V CPM-S125V CPM-REX121 Micromelt Maxamet or any others I don't know about that would be competition in edge retention with the above.
