Abstract

A golf putter has a club head with a golfer's sighting device in the form of an elongated prism positioned at the top of the club head and aligned with the intended location of ball impact on the club head putting face. An elongated colored strip is disposed in or under the prism and appears maximally wide when viewed from above the prism in a vertical alignment plane which includes the impact spot and the upper edge of the prism, thereby indicating that the golfer's head is properly positioned over the club head. The indicator can be used during actual play and/or, in conjunction with a pivotable shaft, to select the optimal angle between the head and shaft in fabricating a custom putter. An aluminum or other oxide coating on the club head provides the putting face with a greater friction and facilitates adherence of a material having low friction characteristis, such as TEFLON, to the bottom surface of the club head. The edge between the putting face and bottom surface tapers upwardly toward opposite ends of the head from the general location of intended impact with the ball to reduce the likelihood of erratic putting strokes due to unevenly cut grass. The TEFLON coating reduces friction between the bottom surface of the putter and the grass to thereby further assure steady, even putting strokes.
