(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 forming a plurality of grooves; 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 overlapping the first region thereby dividing the first region into an overlapped sub-region and a non-overlapped sub-region,
wherein, in step (c), the second region is surface milled at a depth thereby removing material that forms the plurality of grooves located within the overlapped sub-region.
