FIELD: mechanical engineering. SUBSTANCE: method is realized with use of powerful energy source - gas-flame jet directed at angle of 34-37 deg. to work surface. Used for cutters are steels capable of hardening in the air mainly, silicon-manganese steels. Simultaneously, cutter edges are formed, sharpened and thermally hardened. EFFECT: higher efficiency, involving no complicated processes or specific regulation of temperature or other parameters of process. 2 dwg, 1 tbl
