Abstract: A golf club head has a main body and a front recess that includes a flange. A rear portion of the main body includes a perimeter-weighting element. A striking face insert is secured within the front recess. A face center is located on the front surface of the striking face insert. A rear cavity is at least partially delimited by the perimeter-weighting element and a rear surface of the striking face insert. A rear insert is secured to the rear surface of the striking face insert. In an imaginary horizontal plane passing through a portion of the rear insert, proximate a heel portion of the club head, a heelwardmost point of the rear insert is spaced further from a vertical center plane than a minimum distance between the flange and the center plane. The club head comprises an auxiliary recess that extends outward from the rear cavity.

Abstract: A golf club head includes a heel portion, a toe portion, a hosel, and a striking face. The striking face includes a plurality of scorelines each having an average depth no less than about 0.10 mm, a plurality of first micro-grooves each having an average depth no greater than about 0.010 mm, and a plurality of second micro-grooves overlaid on the first micro-grooves, each of the second micro-grooves having an average depth greater than the average depth of the first micro-grooves. Some embodiments can also have a plurality of textured surface treatment regions superimposed on the overlaid first and second micro-grooves so as to at least partially intersect the micro-grooves.
