<p><P>PROBLEM TO BE SOLVED: To provide a club head with improved performance over a larger percentage of a lower part of the face. <P>SOLUTION: A golf club with improved performance over a larger percentage of the strike face, including the lower extremities of the face, is disclosed and claimed. The club head has a coefficient of restitution that approaches substantial uniformity across the face. The golf club head includes a body having a face, a sole, a transition zone between the face and the sole. The transition zone has an internal surface and an external surface. Both the internal and external surfaces have radii of curvature greater than 0.2 inch. The transition zone transitions smoothly from the face, through the transition zone, to the sole. An extension may be provided adjacent the transition zone, cooperating with the transition zone to form a chamber. Dampening and/or weight inserts may be positioned within the chamber. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
