    • A metal wood golf club head has an elongated, forwardly facing front wall (13) to strike a golf ball, and a hollow body (11) rearwardly of the face plate, the front wall being elongated in a first transverse direction toward a connection for a club shaft, the body having a thin, metallic top wall (14) merging with upper transverse extent of the front wall. The head also includes a first group of narrow, metallic, shock wave distributing dendrites (48 to 51) extending from the front wall generally rearwardly adjacent the underside of the top wall and integral therewith; the dendrites are spaced apart in a transverse direction, the maximum height dimensions of the dendrites below the underside of the top wall being between 0.127 and 0.254 cm (.050 and .100 inches) and the dendrites being downwardly convex in cross-section. A second group of such shock wave distributing dendrites (68 to 72) is also typically provided rearwardly of the first dendrite group, and which extend rearwardly to merge with the head rear wall (15).
