Abstract

A golf club having a mechanism permitting adjustment of the shaft angle relative to the club head. Fixed stops limit the range of angular adjustment. The body of the club head has a central opening extending to the sole of the club. The opening is closed by a sole plate that requires a special tool for removal and reinstallation. A serrated surface secured to an extension of the club shaft within the opening mates with a corresponding serrated surface secured to the club head. The angle of the shaft relative to the head is locked by installing the sole plate which forces the two serrated surfaces together. In order to change the shaft-to-head angle, the sole plate must be loosened sufficiently to permit the cooperating serrations to disengage and be moved relative to each other.
