Abstract
Golf club irons of the perimeter weighted type are provided wherein each iron of a set includes a club head having a toe portion, a heel portion having a hosel, a ball-striking face having a plurality of parallel substantially horizontal grooves formed therein, and a generally convex back surface. A cavity is formed in the back surface of each club head and configured to selectively distribute the weight about the perimeter of the head no create a plurality of elliptical force lines concentric with the sweet spot on the club face and having their major axis substantially parallel to the grooves on the club face. Golf irons in accordance with the present invention effectively provide larger sweet spots on the hitting faces of the irons so as to produce results from off-center shots that more closely approach the results produced when balls are struck by the exact sweet spot on the club face.
