Abstract

A golf club comprises a club shaft and a club head connected to an end portion of the club shaft, the club head having a gravimetric center and head body portions extending along mutually orthogonal axes extending through the gravimetric center. At least one of the head body portions is of different geometric configuration on respective opposite sides of the gravimetric center. The club head defines a recess extending to the gravimetric center, the recess having an axis disposed orthogonally to the mutually orthogonal axes. The club shaft end portion is disposed in the club head recess. The club head may include a member secured to an exterior surface of the club head and comprised of a material different from material constituting the club head, the member defining exterior surface for hitting engagement with a golf ball, the member exterior surface having an arcuate configuration.

Claims
