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.
