Abstract
A golf putter head includes a low density insert disposed in a cavity formed in a body. The insert has a front face arranged for impacting a golf ball, and the body has a heel end portion, a toe end portion, a bottom portion and a back portion which define a generally horseshoe shaped mass that partially surrounds the insert. The heel end portion of the body includes a boss projecting therefrom toward the body toe end portion, and a bore located in the boss receives a lower end of a shaft. The insert is preferably formed of polyurethane with a Shore D hardness of 65. The volume of the insert is greater than the volume of the body while the weight of the insert is less than the weight of the body.
