Abstract:
1. A golf club head, the club head comprising: a hollow body having a perimeter region defining an opening; a face insert disposed in the opening, the face insert having a geometric face center and an area of maximum coefficient of restitution; and consists of a single slot disposed on the perimeter region, wherein the area of maximum coefficient of restitution is disposed within a zone on the face insert and the maximum coefficient of restitution is closer to the geometric face center as compared with a club without a slot, and wherein ball speed after impact is increased when the face is impacted in an area from the geometric face center toward the slot and wherein the slot increases the speed at which a golf ball rebounds from the face insert of the club head as compared with a club head without a slot, and wherein the slot is substantially filled with an elastomeric material open to an interior of the hollow body and wherein the elastomeric material does not contact the face insert, and wherein the face insert defines a plane and the slot is disposed on a crown portion of the perimeter region adjacent the face plane.
