A big myth in the knife world is that out there somewhere is a knife that seriously cuts but cannot rust. Knives claiming these super powers are usually made with steels that are unable to hold a cutting edge for any measurable amount of time. Finally a steel foundry in Japan called Myodo Foundry makes this myth a reality with the introduction of a steel called H1. H1 steel is a PH steel, meaning it is a precipitation-hardened steel. "Huh" you ask? Utilizing .1% nitrogen instead of carbon to harden the steel, it reaches a Rockwell hardness of 57-58rc. Spyderco uses H1 on its C91 Pacific Salt model.
