PURPOSE: To secure such an edge tool as being excellent in abrasive resistance and sharpness as well as to make a cut material so as not to stick to it, by forming a hammering uneven surface on a base metal surface of the cutlery material molded in forging,by means of cold forging, and grinding and finishing it after quenching to harden it.

CONSTITUTION: Cutter steel 4 equivalent to U7 of JISS is deposited to a base metal 2 of highly soft steel, making a cutlery material 1 by means of forging, and hammering takes place on a surface of the base metal of the highly soft steel at the normal temperature. Plastic deformation by hammerings 3 should be set to 1W1.5cm in diameter and 0.7W1mm in depth or so in size. Afterward, it is heated at a temperature of about 800°C, quenched to harden it, and it is again heated at a temperature of about 200°C, then tempering takes place, thus a semimanufacture with no strain is secured. Next, this semimanufacture is ground over the whole surface of the cutlery steel in addition to its edging, whereby such a kitchen knife as being excellent in sharpness is securable. Thus excellent in abrasive resistance and, what is more, a cut material can be made so as not to stick to it owing to hammering jogs formed on the base metal surface.
