Abstract
A golf club putter includes a clubhead body sufficiently weighted to define a center of gravity of the golf club, which center of gravity may be adjusted for left and right handed golfers. The putter includes a graphite or fiberglass composite shaft, elongated along a central axis continuously tapering radially inwardly, from: a larger outside diameter adjacent a tip end attached to the clubhead body, to: a smaller outside diameter adjacent a grip end. Preferably, the composite shaft is reverse tapered. The reverse tapered shaft comprises longitudinally oriented graphite or fiberglass fibers in an arrangement that enables shaft torsional distorting forces imposed at the grip end during putting to be imparted to the clubhead and a golf ball thereby.
