A correlated set of golf clubs the heads of which each have a top ridge that extends longitudinally along the upper part of the head between the heel and toe ends thereof with enlarged mass concentrations being formed to provide upper protuberances at the heel and toe ends of the ridge. The top ridge and the upper heel and toe protuberances are especially configured to locate mass concentrations high on the heads and set back from the striking faces thereof to provide the club heads with an improved ability to resist twisting of the club heads upon laterally off-center impacts with a golf ball and to resist tiling of the club heads upon vertically off-center impacts with a golf ball. |
