O2 Tool Steel

O2 tool steel is an oil hardening tool steel that is supplied in the annealed condition and characterised by its characteristics of offering good durability. Tool steel O2 is with excellent wear resistance and its ability to hold a good cutting edge. 02 steel is a good quality general purpose tool steel often used where the expense of a high carbon high chromium tool steel would not be justified.

AISI O2 steel has a working hardness up to 63-65HRC. Steel O2 makes a pretty decent performer for light/medium use knives at that hardness.
