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.
