Abstract
A correlated set of golf clubs of the iron type is disclosed in which each club head has a cavity formed in the back surface thereof with specially configured weight pads formed integrally within the back cavity. The weight pads are so configured and positioned within the confines of the back cavity as to create desired heel-toe balancing of each club head wherein each club head's center of gravity physically centered, both horizontally and vertically of the club head, behind the visually-perceived optimal striking point. i.e., the apparent visual center of percussion, of the golf club's striking face relative to the golf ball at address. In the preferred embodiment the configured weight pads are so varied in size and position throughout the set of correlated golf clubs heads as to consistently maintain, for each head, the club head's center of gravity directly behind and in alignment with the club's apparent visual center of percussion.
