Abstract: A golf putter is disclosed that includes a shaft and a head secured to the shaft. The head includes a forward portion that defines a face, and the head includes a rear portion positioned rearward of the face. The rear portion may have the configuration of a ring structure. Whereas the forward portion is formed of a first material, the rear portion may be formed of a different material with greater density. In manufacturing the head, the rear portion may be formed and then placed within a mold having the shape of the entire head. Molten first material is then introduced into the mold to form the forward portion.

Abstract: A golf club head is disclosed that includes a primary element and an insert element formed of different materials. The insert element is located within a cavity formed by the primary element. The cavity is defined by a portion of the primary element that is of unitary construction, and the cavity is positioned between a face and a rear surface of the head. At least a portion of the cavity extends in a direction that is substantially parallel to the first surface. Another aspect of the invention involves a method of manufacturing the golf club head that includes forming the primary element. The cavity is then defined within a portion of the primary element that is of unitary construction, and the insert element is positioned within the cavity.
