ABSTRACT:
A method of forming a jaw for biopsy forceps with a very sharp edge. An initially flat metal plate is first relieved to form a recessed area extending along an edge. The edge is then honed sharp. Finally the plate is folded to bring the relieved areas into facing relationship to form a cup whose sharp edge extends along the edge of the cup, including around the bight formed by the bend.
