Abstract
A correlated set of golf clubs the heads of which each contain (1) a sole including a trailing edge which is indented toward the striking face a distance of at least 1/16 of an inch, and (2) a lower back surface adjacent the indented trailing edge sloping upwardly and inwardly from the indented trailing edge toward the striking face. This configuration allows the club head material which would otherwise be located in the indented areas to be redistributed in the heel and toe portions of the club heads. The redistributed head materials increases the mass concentrations in the heel and toe areas which improves the resistance to twisting of the club heads upon off-center impacts with a golf ball.
