Abstract
Abstract A golf putter has a hard grip or an all-metal grip, and the grip, shaft and head are formed of a single, stiff material, or materials having closely-related moduli of elasticity, into an integral structural element. It is cast, forged, bonded, or otherwise assembled, to achieve a stiff, but sensitive "feel", for the golfer. A low frequency "feel" and sound is obtained by the shaft being closed at both ends and by one or more sound chambers or resonating elements. No dissimilar materials are included between the "sweet spot" and the golfer's hands, including in the grip. In one embodiment, toe area loft of the head is greater than the center loft and the heel area loft is less than the center loft. The putter head toe area may be closed slightly and the heel area may be opened slightly. A bulge may be included in the heel or toe areas.
