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 bounded 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.

Claims12

Dependent claims

A method of manufacturing a golf club head, the method comprising:

(a) providing an intermediate golf club head body that, when oriented in a reference position, has a heel portion, a toe portion, a top portion, a bottom portion, and a striking face having a striking face periphery;
(b) texturing a first region of the striking face by surface milling in a first pass;
and
(c) texturing a second region of the striking face subsequent to step (b) by surface milling in a second pass, the second region partially covering the first region thereby dividing the first region into an overlapped sub-region and a non-overlapped sub-region, the non-overlapped sub-region of the first region having a first average surface roughness Ra1, and the second region having a second average surface roughness Ra2 that is less than Ra1.
