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.

Golf club with lockable head-to-shaft angle adjustment

A golf club with a shaft angularly adjustable relative to the head through selected angles. A special tool must be used to allow any angular adjustments between shaft and head. A structural stop limits the maximum and minimum angles of adjustment between the head and shaft.

Golf club with lockable head to shaft relative angle adjustment

A golf club that produces a smoother stroke, does not attempt to turn in the golfer's hands, and provides superior feedback to the golfer comprises a putter head, a shaft, and a grip. The putter head comprises an elongated body having a toe end, a heel end, a fore side including a ball striking face, an aft side opposite said fore side, a sole, and a top side. A longitudinal axis runs heel to toe parallel with the ball striking face. The head includes two chambers that increase the proportion of heel and toe mass relative to the center mass and decrease the transverse cross sectional area of head material and thereby increase vibration up an attached shaft upon ball impact. The chambers each exit the top side in a transverse slot. The transverse slots are approximately a ball width apart and equal distance on each side of the center of mass of said head. The entire putter is balanced so as to be more stable in a golfer's hands. A neutrally balanced putter has no moment about the shaft axis. A face balanced putter has weight distribution such that, when the putter may freely rotate about the shaft axis, the putter will come to rest with the head longitudinal axis level.
