Abstract
A method of manufacturing a golf club head includes: providing an intermediate golf club head body; prescribing a scoreline length value based on at least a first final spatial attribute of the intermediate golf club head; and texturing a first region of the striking face to exhibit a first average surface roughness Raof greater than 180 μin by surface milling in a first pass to form a plurality of arcuate micro-grooves each having a radius of curvature selected based on at least a second final spatial attribute of the intermediate golf club head. The method further includes texturing a second region of the striking face to exhibit a second average surface roughness Rathat is less than Ra, and it includes forming a plurality of scorelines in the striking face, the plurality of scorelines defining a scoreline length LS substantially equal to the prescribed scoreline length value.
