Abstract:
1. A wood-type golf club head comprising: a face having a ball striking surface configured for striking a ball and a rear surface opposite the ball striking surface, with a thickness defined between the rear surface and the ball striking surface, the face having a thinned portion where the thickness is smaller than the thickness of surrounding areas of the face, the thinned portion forming a recess on the rear surface of the face that is recessed relative to the surrounding areas of the face, the recess being defined between a first edge proximate a geometric center of the face and a second, opposed edge proximate one of a top edge and a bottom edge of the face; a body connected to the face and extending rearward from the face to define a cavity bounded by the face and the body; and an insert connected to the rear surface of the face, the insert being received within the recess and filling at least a portion of the recess, wherein the insert is comprised of a first material and the face is comprised of a second, metallic material, and wherein a density of the first material is lower than a density of the second material, and wherein a center of gravity of the insert is vertically offset from a geometric center of the face, and the lower density of the insert causes a center of gravity of the face to be offset from the geometric center of the face in a direction away from the center of gravity of the insert.
