Abstract
Abstract To promote control and accuracy during the putting stroke and to provide a more comfortable and efficient grip on the putter, a somewhat bulbous handle is provided on the club including substantially flat surfaces on the sides and top of the hand grip for the forefingers and the two thumbs. The under side of the hand grip is transversely arcuate to comfortably accommodate the remaining fingers in interlocked relationship. From the top of the club shaft rearwardly, the hand grip cross section is of modified rectangular form gradually becoming circular and gradually enlarging to a point near the longitudinal center of the grip.
