Abstract: A device for the removal of unwanted excess skin from an area of the human body to be treated in which a carrier encases a planing blade. The blade body is formed from a blank and co planer uniform opposed cutting edges protrude upwardly in a uniform transition beyond the plane of the blank in order to contact the skin to be removed while the device is moved to and fro across the area of the skin to be treated.

Abstract: A disposable acetabular reamer having a cutter blade (16) molded into the surface of a support (11). The cutter blade is formed of a single flat sheet of metallic material having a series of teeth (24) formed thereon which protrude above the surface of the support such that when the acetabular reamer is rotated, the teeth contact and reduce the surface of a boney socket. The invention includes a novel method of forming the reamer which includes shaping the cutter blade once teeth are formed therein and integrating the cutter blade into the support coincident with the shaping process. The assembled unit is so economical that it may be discarded after use.
