Abstract

A metal wood type golf club head including a club head body and means for attachment to a golf shaft, the club head body including a frontal ball striking face having a center of percussion thereon, a rear face, a heel, toe, and top crown, and a rigid, non-deformable bottom sole having a forward section and at least one additional rear section. The forward section provides a friction surface and is defined by a bounce angle extending downwardly from said frontal ball striking face to prevent the leading edge of the club head from digging into the turf or ground during the execution of a golf shot. The rear section of the bottom sole is a reduced friction surface and is recessed upwardly into the club head.
