Abstract

A golf club putter including a reversed shaft, with a thin end in the grip and a thick end in the head, a shaft at the true center of gravity, and a shaft through a tapered hole in the head. The golf club putter can also include a head with hollow construction at the exact center of the head providing the putter head with a true and exact toe-heel balance relative to a shaft. The reverse tapered shaft slides through the putter head, and frictionally engages in the head with a thin end of the shaft in a grip and a thick end of the shaft in the head. In the alternative, the shaft can glue onto a pin extending upwardly from the putter head.
