Abstract: A wood-type golf club head comprising toe, heel, top and sole portions, a front face bounded by the toe, heel, top and sole portions, and a rear wall bounded by the toe, heel, top and sole portions, a peripheral wall depending from the periphery of the sole portion to define a sole cavity in the sole portion, and two struts extending from a portion of the peripheral wall adjacent the front face to a portion of the peripheral wall adjacent the rear wall, the struts being in part substantially parallel to each other and in part diverging from each other and defining therebetween and in cooperation with the portion of the peripheral wall adjacent the front face, a central portion of the sole cavity, the peripheral wall being interrupted adjacent the rear wall, such that the central portion of the sole cavity is open to the rear of the club head.

Abstract: An iron type golf club head comprising a heel portion, a toe portion, a bottom sole portion, a top ridge portion, a hosel portion, a face surface having a center of percussion, a rear surface, a peripheral mass formed on the rear surface adjacent the heel, toe and bottom sole portions, the peripheral mass being further formed on a portion of the top ridge portion, with substantially the remainder of the top ridge portion being devoid of the peripheral mass, and a weight portion extending from the rear surface and disposed behind the center of percussion.

Abstract: An iron type golf club head including heel, toe, bottom sole, top ridge and hosel portions, a face surface having a center of percussion, a rear surface, a peripheral mass formed on the rear surface and forming a cavity, a first weight portion extending from the rear surface and disposed behind the center of percussion, and a second weight means extending from the rear surface and at least in part spaced from the first weight portion.
