Abstract: A golf club head comprises a loft angle no less than 18°, a striking face, a sole portion, and a top portion having an exterior surface. In an imaginary vertical plane spaced from a face center by no more than 10 mm and perpendicular to an imaginary striking face plane, an imaginary line segment has a length of 25 mm, a first endpoint located in the imaginary striking face plane, a second endpoint located above the exterior surface, and forms an angle ? with the striking face plane between 55° and 65°. The line segment is tangent to the exterior surface at a first point. A second point is located on the imaginary line segment and spaced from the first point by no less than 1 mm. The second point is spaced from the exterior surface by a gap distance that is no greater than 0.15 mm.

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.
