Spyderco Salt I Black FRN Folding Knife (3" Satin Serr) C88SBK - Blade HQ

A myth in the knife world is that, out there somewhere exists steel with high-performance cutting abilities that cannot rust. A Japanese steel foundry recently turned this myth into reality with the introduction of a steel they call H1.* H1 is a PH steel meaning it is a precipitation-processed alloy, that's rolled hard without heat-treating and has .1% nitrogen which acts like carbon in the steel matrix, but does not react to chlorine making rust. Surprisingly, it holds a sharpened cutting edge comparable to the premium knife steels being used in the industry by most knife manufacturers.
