A work 10 made of a hard wire rod of austenitic-stainless steel is pressed at a rolling reduction of 60% or greater, into a paddle-shaped end 10 b, and then subjected to work hardening, making the hardness of the end 10 b 550 Hv or greater. Afterwards, the paddle-shaped end 10 b is cut through machining, forming a main body 10 c of a medical knife and cutting blades 10 d. As a result, a medical knife, which is easily fabricated, is corrosion resistant, has sufficient hardness and sharpness, high toughness preventing cracks, can be provided.
