  • Patent number: 4642894
    Abstract: A grinding instrument, especially adapted to permit wearer adjustment of dentures, comprises an S-shaped handle, a straight shaft and a blade, the handle, shaft and blade all being integral sequential members of a unitary, elongated cylindrical wire. In a preferred embodiment the wire is made of a seven and one-half inch length of four millimeter diameter carbon steel wire in a novel process comprising the steps of:cutting a carbon steel wire to a selected straight length,bending about one-half of said length of wire to form a handle,stamping the terminal portion of the unbent half of said length of wire to form a shaft terminating in a blade, andgrinding at least one surface of said blade at a selected angle relative to the longitudinal axis of said shaft to form a grinding edge.
