Abstract
A metal wood golf club head has an elongated, forwardly facing front wall to strike a golf ball, and a hollow body rearwardly of the face plate, the front wall elongated in a first transverse direction toward a zone of connection to a club shaft, the body having a thin, metallic top wall merging with upper transverse extent of the front wall. The head also includes a first group of narrow, metallic, shock wave distributing dendrites extending from the front wall generally rearwardly adjacent the underside of the top wall and integral therewith; the dendrites spaced apart in a transverse direction, the maximum height dimensions of the dendrites below the underside of the top wall being between 0.050 and 0.100 inches and the dendrites being downwardly convex in cross-section. A second group of such shock wave distributing dendrites is also typically provided rearwardly of the first dendrite group, and which extend rearwardly to merge with the head rear wall.
