Abstract: A golf putter which aids a golfer in aiming a putt and avoiding twisting of the shaft in the hand during a swing includes a head provided with a pair of laterally spaced apart trailing members which protrude rearwardly of the rear surface of the head and function cooperatively as weighting/aiming members. The trailing members are preferably located equidistant from a vertical center plane through the sweet spot of the head and have in plan view longitudinally directed visual features perpendicular to the front ball-impacting face of the head, which assist a golfer in visually framing an intended initial ball trajectory to a target hole on a golf green, along with a ball impact vector perpendicular to the center of percussion or sweet spot of the head. Each of the trailing members is preferably laterally symmetric, and may include a longitudinal index line marked on the upper surface of the member, to facilitate visual framing of a putt.

Abstract: A golf putter has most of its weight in the upper half of the putter head so the hitting force against a ball is directed horizontally, reducing lift on the ball and causing the ball to roll sooner. A rectangular slot is formed through the center of the putter head, immediately behind the putter face, and is the same width as the diameter of a golf ball so the edge of the ball and the sides of the rectangular slot are integrated by the player's eye to create an alignment used to aim the ball to the hole. The putter shaft and hand grip are stiff to minimize bending action upon contact with the ball. The present grip on the shaft has a generally square cross-section, allowing for a better and consistent fit in the player's hand. The putter preferably incorporates a solid brass head, and also is designed with most of its weight in its upper half to produce a high center of gravity, while conforming to USGA rules.
