Abstract
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.
