Crucible Airkool-V Knife Steel
Composition Analysis Graph, Equivalents And Overview

Airkool-V(Crucible) - Some sources refer to it as AISI T15 No Co, but that's not really correct, A7 is quite different. It is an air hardening, cold work tool steel. A7 has very high wear resistance, thanks to strong carbide formers like V, W, Mo. Presence of 2.00-2.58% Carbon makes it possible to attain hardness up to 64-66HRC. That'd be for light/medium use knives obviously.
