Abstract:
A golf club head includes a striking face with a plurality of scorelines. A first virtual vertical plane is perpendicular to the striking face and passes through a toe-wardmost extent of the scorelines, and a second virtual vertical plane is parallel to the first virtual vertical plane and passes through a heel-wardmost extent of the scorelines. A central region bounded by the first virtual vertical plane, the second virtual vertical plane, and a striking face periphery has a first average surface roughness Ra1 of between about 40 μin and about 180 μin. And a majority of a toe region hounded by the first vertical plane and the striking face periphery is textured to have a second average surface roughness Ra2 no less than 1.5 times Ra1.
