Steel golf club head having reduced face thickness and optimum distributed mass

Abstract

A golf club head is comprised of cryogenically treated steel resulting in the striking face having a reduced face thickness of between 0.115 inches and 0.130 inches, and therefore, a reduced striking face mass. Extra material which is eliminated from the striking face, is distributed in other areas of the club head to enhance performance. In an iron club head embodiment, the club head includes a heel portion, toe portion, bottom sole portion, top ridge portion, hosel portion, striking face, rear surface, and peripheral mass on the rear surface which forms a rear cavity. A cantilevered mass extends from the bottom sole portion toward the top ridge portion within the rear cavity, spaced apart from the rear surface. In a wood club head embodiment, the club head includes a hollow body having an inner cavity delimited by a sole portion, a striking face, a heel portion, a toe portion, and a crown portion which links the striking face, toe portion, and heel portion. A weight chip of higher density material is located along the sole portion of the head. The iron and wood embodiments enjoy an optimum weight distribution which is below and behind the sweet spot, producing higher trajectory golf shots and more forgiving off-center hits.
