Abstract
Abstract The head of a golf putter is substantially rectangular in shape and has a weight distributing channel formed in the top thereof which extends through one end of the putter head. Within the channel is mounted a shaft-receiving boss adapted to hold the shaft of the putter at an angle such that the putter can be held close to the feet of the user with the bottom surface of the putter parallel to the putting surface. The bottom of the putter head has an upwardly curved rear surface and the front and side walls are inwardly tapered from bottom to top. The weight distribution of the putter head together with the shaft angle allow the putter to be employed with a one-arm pendulum-type swing for improved putting accuracy.

Claim 1
Independent Claim
228 words
A golf club head comprises a substantially rectangular body having front and rear ends and a top surface, said body including an open channel formed downwardly through said top surface into said body to define a floor of said channel, said channel extending through said rear end and forming first and second walls of said club head; said open channel including a beveled surface at an end of said channel adjacent said front end of said club head, a step joining said beveled edge and the remainder of said channel, said step having a surface which lies intermediate said top surface of said club head and said floor of said channel and lying in a plane substantially parallel to said top surface; said body including an exterior bottom surface which is substantially flat at the front and middle portion and curved upwardly at said rear end of said body; and a shaft receiving boss integrally molded to one of said walls of said body and said floor of said channel, said boss including an aperture adapted to receive and hold a club shaft at an angle of 75* to 80* inclusive between the longitudinal axis of the shaft and the plane of the top surface of the club head to enable the club head to be positioned on the ground relatively close to the feet of the user.
