  • Patent number: 6213890
    Abstract: The instant invention provides a putter for use by a golfer in playing golf. The putter includes: a shaft long enough to rest against the abdomen; a head of greater than conventional mass fixed to the first end of the putter; and, a handle fixed to the second end of the putter. The handle further includes: an upper hand grip; a lower hand grip substantially length to rest against the abdomen navel dimensionally spaced from the upper hand grip; and, a counterweight positioned within the handle substantially near the upper hand grip, for providing the putter with a conventional center of gravity. The putter is designed for maximizing the sweet spot of the head while enabling the golfer to putt a golf ball by pivoting the putter substantially only at a point located at about the upper hand grip, from an otherwise conventional crouched stance.
