Abstract
A golf ball putter club has a generally rectangular blade head with a front putting face, a substantially flat rocker bottom, an upright back wall, and a central cylindrical portion having a diameter matching the diameter of a golf ball to be putted with narrow heel and toe portions projecting laterally from this central cylindrical portion. The top half of this cylindrical portion extends above the heel and toe portion and matches the top half of the golf ball to be easily aligned behind the ball and present a 'sweet spot' on the putting face at the axis of the cylindrical portion. A shaft extends upwardly from the central cylindrical portion of the blade with its axis intersecting the longitudinal axis of the cylindrical portion for transmitting putting energy in alignment with the sweet spot. The equatorial plane of the central cylindrical portion is level with the tops of the heel and toe portions and longitudinal grooves are cut into the ends of this plane to better define and sharpen for ease in sighting, the semi-cylindrical portion which extends above the narrow heel and toe portions. These grooves also provide sighting lines for straddling of the ball to facilitate alignment. The central cylindrical portion may have a depth greater than the narrow end portions and the shaft or hosel of the shaft preferably enters the cylindrical portion closely adjacent the extension so that a substantial portion of the top face of the cylindrical portion will be forwardly of the shaft. The shaft preferably slopes at about an angle of 70.degree. from the longitudinal axis of the blade.
