Abstract: A golf club head consisting of more than one piece has a joint which holds the pieces together. Characterized by a mechanical interlock, the joint of the invention is formed by preparing a specialized insert with a recess long the periphery of the front side. In addition, a specialized golf club head body includes a ridge of malleable material about a opening operable for receiving the insert. After the insert is placed into the seat in the body, the ridge of malleable material is pushed over and into the recess of the insert. The insert is held fast to the club body and forever and permanently integrated therewith. The joint provides a stronger, cosmetically more attractive, and inexpensive club.
