Golf club head with textured striking face

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 portion of the striking face by surface milling in a first pass;
• (c) texturing a second portion of the striking face subsequent to step (b), the second portion being non-coextensive with the first portion;
• and
• (d) forming a plurality of scorelines in the striking face, wherein:
• the steps (b) and (c) combine to form a textured striking face area including a first region exhibiting a first average surface roughness Ra1 no less than 270 μin and a second region exhibiting a second average surface roughness Ra2 that is less than Ra1;
• a first virtual vertical plane perpendicular to the striking face passes through a toe-wardmost extent of the scorelines;
• a second virtual vertical plane parallel to the first virtual vertical plane passes through a heel-wardmost extent of the scorelines;
• the first region is located entirely toe-ward of the first vertical plane;
• and
• the second region extends entirely over the region of the striking face delimited by the first and second virtual vertical planes.
