发明名称 Golf club head
摘要 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.
