    Abstract: A golf club head includes a striking face having a face center and a virtual striking face plane generally parallel to the striking face. The golf club head further includes a sole portion, a top portion, a rear portion, and a loft L no less than 40°. A virtual vertical plane perpendicular to the striking face plane passes through the face center. A club head center of gravity is spaced from the virtual vertical plane in the heel-to-toe direction by a distance D1 that is no greater than 6.0 mm. The golf club head further includes a hosel including an internal bore configured to receive a golf shaft. The internal bore includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf club shaft. The hosel further comprises an auxiliary recess extending sole-ward from the abutment surface of the internal bore.

    Abstract: Provided are a golf club head and a method for producing the golf club head. The golf club head comprises a striking face that in turn comprises a recurrent texture pattern that has a period T and that is defined by a plurality of depressions, each depression having an average depth no greater than 0.10 mm. The striking face also comprises a plurality of scorelines that at least partially intersect the recurrent texture pattern and that have a scoreline pitch Ps such that T/Ps is greater than 1.0, each scoreline having an average depth no less than 0.10 mm.

    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.
