Abstract
A metallic golf club head having a rear side recess and a synthetic backing situated in the rear side recess, wherein the position of the rear side recess is selectively offset towards the toe of the golf club head in a short club and towards the heel of the golf club head in a long club so as to selectively position the center of gravity of the golf club head and thereby provide a more stabilized course of travel for a ball impacted by the golf club head, increase the distance traveled by a ball impacted by the golf club head and provide a crisp feel when a ball is impacted by the golf club head.
Claims4
A set of metallic golf clubs having shafts varying in length from short to long, each said golf club having a golf club head, said golf club heads having blade lofts varying in degree from low for the golf clubs having longer shafts to high for the clubs having shorter shafts, each said golf club head comprising a main body member having a front side, a rear side, a toe, a heel and a predetermined central location centrally located between said toe and said heel, said rear side including a recess, said front side including a wall section having an inner surface in communication with said recess and a shooting surface remote from said inner surface, said recess having a predetermined length defined by two recess ends and a recess center between said recess ends, said recess center being in a predetermined offset position with respect to said predetermined central location thereby offsetting said recess, the golf club heads of the golf clubs having shorter shafts and higher blade lofts having said recess offset towards the toe and the golf club heads of the golf clubs having longer shafts and lower blade lofts having said recess offset towards the heel, thereby selectively providing the optimum center of gravity for each golf club head so that a ball struck with the shooting surface of any golf club head in said set of golf clubs will travel a substantially stabilized course.
