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, andwherein 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, andwherein the slot is an elongated slot substantially parallel to a portion of an edge of the body.

Abstract
A golf club head is provided having a body and a face insert, with a slot in a perimeter region of the body of the club head adjacent the face insert. The slot increases the flex of the hitting surface on impact with a golf ball, thereby increasing the speed with which the ball rebounds off the hitting face and increases the overall distance the ball is hit. The slot preferably moves the sweet spot of the hitting face a distance X from the face center of the hitting face. The slot may be filled with an elastomeric material.
