ABSTRACT:
A cutter for soft materials is described. The cutter is made from a conventional cutting instrument such as a dental drill bit having hard particles embedded in the tip surface. The cutter is ground at the tip end so as to remove particles which leave cavities around the peripheral fiat ground tip end. The open cavities and the sharp edges around them provide an effective cutting edge with which soft materials can be cut in clean even lines.
