Abstract
Embodiments of the surgical chisel assembly comprise a wedge shaped surgical chisel designed to eliminate the square shape and sharp corners from a forward edge of a chisel. One embodiment of the chisel assembly comprises a chisel body and a grip. The chisel body comprises a wedge-shaped blade portion and a handle portion. In one embodiment, the handle portion is substantially flat about two generally parallel principal surfaces and is generally shaped to be able to be comfortably held by a surgeon in their hand. The blade portion of the chisel comprises a forward edge created by a blunting of the angle of intersection of the forward edge surfaces and a curving of the forward edge along the width of the forward edge.
