Abstract

A golf club head for an iron has a dual sole comprising first and second discontinuous surfaces which intersect along a diagonal line between the leading edge of the head at the toe and an intermediate point on a trailing edge of the head. The soles progressively taper from the long irons to the short irons so that the intersection of the diagonal line with the trailing edge is progressively closer to the toe. The head construction reduces weight in the toe and ground contact in the toe area, and moves the center of resistance toward the heel of the club. This reduces head droop and the tendency of the toe to dig into the ground, and, minimizes opening of the face at impact.
