发明名称 Putter
摘要 A hollow, double-faced mallet-shaped putter is made from a plug and a cap into which the plug fits. A handle is inserted through the body of the cap. In one embodiment the cap may be fabricated from a pipe cap, the peripheral flange being removed and the exterior machined cylindrical, and a pipe cap threaded therein, the wrench grip of the plug being removed after insertion. Both ends of the putter are machined flat and perpendicular to the central axis of the club head.
