Abstract
A golf club head includes a golf club head body, a striking face, and an inner wall supporting the striking face. A ledge extends from a body into the interior of the golf club head body, and the inner wall is disposed within a gap between the striking face and the ledge. A rear surface of the inner wall is supported by a portion of the golf club head body, and a rear surface of the striking face is in contact with a portion of the inner wall. The inner wall may be inserted into the golf club head through an opening defined in the toe portion of the golf club head or the rear portion of the golf club head.
