Abstract
Method of producing a medical cutting tool and a medical cutting tool that will not rust and that is capable of stably demonstrating high strength. A working section formed by a cemented carbide or ceramic is brazed to the tip of a shank part formed by a round bar-shaped austenitic stainless steel, thereby constituting a cutting tool. The shank part includes a shank, a neck, and a joint to which the working section is brazed. At least part of the stainless steel near the joint of the neck and in the joint has a fiber-like structure. The structure of the stainless steel in the joint on the working section side has a granular structure.
