Golf putter head with increased dimensions and increased moment of inertia

A golf putter includes a putter head having a face member, a heel end, a toe end and a rear member extending in an arcuate path from one end of the face member to the other end of the face member. First and second struts extend and are connected to the rear member and the face member while converging toward each other as they approach the face member. A third strut extends between and is connected to the rear member and the face member and lies between the first and second struts. The putter head has a width W of at least 15 centimeters and a depth D that is at least equal to ½ width W. In its preferred embodiment, the putter head has a width W of approximately 17 centimeters and a depth D of approximately 10 centimeters.
