ABSTRACT:
The club head of a golf putter has a substantially flat bottom surface to facilitate alignment of the putt and is symmetrically weight-balanced that it's heel-to-toe center to reduce torque effects and lower its center of gravity. The weight balancing is achieved with a dense sole plate having an elongated intermediate section joining two mass-concentrated heel and toe ends. A less dense body portion provides a soft putting face and has hollowed portions to further lower the center of gravity and concentrate the club head weight at the heel and toe. The front corners of the bottom surface are cut away to reduce scuffing during a golfing stroke. A sighting device on the club head facilitates alignment of a golfer's line of sight in a vertical plane which includes the golf ball, the club head "sweet spot" and the putting target when the golfer's eye is positioned above and rearwardly of the club during alignment of the putt. The sighting device includes a rectangular recess in the upper surface of the putter and strategically located sighting lines on the upper surface and in the recess. The heel-to-toe center of the club includes the center of gravity and the "sweet spot" and is coraxially aligned with the club shaft. The lower end of the club shaft is bent rearward of the club head to an attachment point on the rear surface of the club head, centrally between the heel and toe portions.
