1. In a metal wood golf club head having an elongated, forwardly facing front wall to strike a golf ball, and a hollow body rearwardly of the face plate that includes a curved rear wall, the front wall elongated in a first transverse direction toward a connection to a club shaft, the body having a thin, metallic top wall merging with upper transverse extent of the front wall, the combination comprising:

  • a) a first group of narrow, metallic, shock wave distributing dendrites extending from said front wall generally rearwardly adjacent the underside of the body top wall and integral therewith,b) the dendrites spaced apart in said transverse direction, by amounts greater than their widths, the maximum height dimensions of the dendrites below the underside of the top wall being between 0.050 inches and 0.100 inches and the dendrites being generally downwardly convex in cross-section,c) there being a second group of dendrites integral with said top wall and which are spaced apart in said transverse direction, and which extend generally rearwardly to merge rearwardly and downwardly with said curved rear wall to transfer rearward loading to that wall as the dendrites pick up rearward loading from said top wall in response to front wall impact with a golf ball.
