Hand ground and hand finished blade made of Heat treated and Cryo treated HRC 60 440C Stainless Steel.
Handle Finish: BrightMetal

   The 450SS H900 Hardened Stainless Steel handle set is given a natural textured finish that reflects light with an even sheen, using micro shot peening to further harden the surface and optimize its scratch resistance.  The second to last step is laser marking and engraving, brand, model, serial number, and then a deep laser engraved grip pattern are applied to the handles and blade.  The surface is further treated to passivation to ensure the handles and blade have a superior corrosion resistance.
