Abstract

A method for producing cutting instruments based on stainless and semi-stainless martensitic steel, characterized by rapidly heating and cooling said steel under conditions that will provide a residual austenite content of approximately 35 to 95% and after this harden the edge zones cutting by cold work until the austenite content retained in these areas is at least less than 30%.
