Very advanced steels (at least S30V is).
A2 is known as "The Toughness Champ" (or something like that) by the modern world. It's a Hi-Carbon Air Hardening Tool Steel. I don't know how it performs, as I don't have any knives made from it. A2, like all stainless steels is an Air-Hardening Steel, but unlike Stainless, it lacks the high Chromium content that makes them so brittle. It has quite a high Molybdenum content, allowing it to harden in air, with the benefit of holding it's hardness at very high temperatures. I know high speed steels like M2 have a high Moly content as well. It also has a high carbon and Vanadium content, that enables it to hold a fantasic edge. It's currently being used in with all them newfangled "combat knives". I know Mission Knives, who boast that they supply the knife used by Navy SEAL Dive Teams use A2 in their fixed blades. Chris Reeves uses it in his one-piece series of hardcore survival knives. A2 is also being used by... Damnit! I can't remember his name, but he makes modern "Katana" which are incredibly tough...
CPM-S30V is a truely advanced steel. "CPM" stands for "Crucible Particulate Metallurgy", which involves smelting stainless with mind-boggling Carbon, Chromium, and Vanadium contents. These levels are set after a discussion and input by customers, knifemakers and metallurgists (I think). The steel is then melted down and then sprayed through an fine-apertured nozzle into a vacuum, which cools the molten steel into a very fine powder. Each individual speck of powder contains *THE EXACT* proportion of each element in *EACH INDIVIDUAL* speck... This powder was then formed into billets/sheets. What you get is an incredibly pure, clean, hard, and expensive stainless steel that's quite tough in short blades like tac-folders and neck-knives. This "Perfect Knife Steel" (as it has been called by some) is becoming very popular among the custom knife industry. I'm quite sure Chris Reeves uses it in his latest run of Sebenzas...
That's 'bout all I know...
Any other questions?
