Abstract:
1. A composite golf club putter, comprising: a putter head sufficiently weighted to define a center of gravity of the golf club, the putter head comprises a toe, a heel, and a center section, the center of gravity being at the center section approximately equidistant from the toe and the heel; and a putter shaft elongated along a central axis between a tip end and a grip end, the tip end attaches to the putter head at the center of gravity, the putter head and the putter shaft are configured to impart spin on a golf ball during a putting stroke to reduce breaking; wherein the putter shaft comprises substantially continuous unitary fibers longitudinally oriented around a hollow center, the continuous unitary fibers disposed from the tip end to the grip end, the continuous unitary fibers are characterized by a low modulus of elasticity and a low torsional resistance, the continuous unitary fibers are embedded in composite matrix in an arrangement that enables shaft torsional distorting force imposed during the putting stroke to be imparted through the putting shaft to the putting head and a golf ball thereby to impart the spin when the golf ball is struck with the putter at one of the toe and the heel of the putter head.
