A method of making a femoral rasp wherein the hip stem implant is used to make a two part mold. The mold halves are separated and the implant removed to yield left and right mold halves representing corresponding halves of the hip stem. The cavities of the mold halves are lined with wax and a plurality of blades are imbedded into the wax such that an anchor portion of each of the blades remains exposed. The mold halves are connected together and a stem of handle is inserted therein. A moldable material such as PMMA is poured into the mold and allowed to cure. When the PMMA is hard or cured, the mold halves are separated and the wax is removed from the rasp body exposing the cutting surfaces of the teeth.
