ABSTRACT:
An improved dual weight correlated set of iron-type golf clubs, each club having a neck to attach to a shaft, and a face for impacting a golf ball, a back surface, a heel portion, a toe portion, and a sole, wherein the improvement comprises: reinforcement periphery balancing weight structure placed along the perimeter of the back of the club defining a cavitated back, the balancing weight structure having least weight and thickness starting at the top of the back of the club and gradually increasing in weight and thickness toward the sole of the club along the perimeter of the toe, sole, and heel to provide better balance and strength behind the periphery of the hitting surface of the face of the club, and a second mound weight reinforcing structure partially filling the cavitated back of the iron-type club behind the hitting surface of the club, with a curvilinear base reinforcing the sole of the club and a mound mass curvilinearly rising from low points proximate the toe and heel along the sole and gradually rising to a peak, filling the middle of the back of the cavity of the club behind the lower segment of the hitting surface of the club face to add center weight behind the segment of hitting surface of the club face wherein a ball leaves impacts and leaves the hitting surface.
