ABSTRACT:
An improved set of golf clubs has iron club heads in a correlated set such that the weight of longer shafted, less lofted clubs is concentrated more towards the heel of the head, while the weight of the shorter shafted, more lofted clubs is concentrated more towards the toe of the head. When viewed face on, with the sole of the club on a level surface, it will be noted that the vertical plane of the center of gravity of each individual head shall be shifted towards the toe or the heel, as the case may be, with such weight concentrations. The result is a set of correlated golf club heads which: (a) have less inertial drag in the longer, less lofted clubs, (b) have more inertial drag in the shorter, more lofted clubs, and (c) can utilize the gear effect phenomenon inherent in golf clubs more effectively.
