Patent attributes
A golf club putter includes a head having an insert including face and base portions that interface with each other and are made of materials with dissimilar moduli of elasticity. The face portion can be a polymer and the base portion can be a metal. The face portion has a front facing surface that strikes the golf ball and an opposing rear surface with a smooth curved or stepped angled profile. The base portion has a front surface that interfaces with the rear surface of the face portion and is curved or stepped similar to the face portion. The front-to-back dimension of the face portion is thinnest at the center of the club head, and its thickness progressively increases as the curve of the rear surface of the face portion moves away from the club head center towards the heel and toe of the club head.
