Supra2(Akers) - Akers' proprietary alloy. High wear resistance coupled with decent hardness, as in for the light/medium use knives. Working hardness 64-66HRC. Composition matches Erasteel's ASP2017 high speed steel one to one, except for the missing Niobium in Supra2. Akers doesn't list Niobium in Supra2, but mentions it is a special edition alloy. Still, I am quite sure nobody would hide Niobium presence in their high performance steel, since Nb is one of the best carbide formers.
