ABSTRACT:
The present invention consists of an improved wood head or driver design for a golf club in which the wood head or driver is preferably molded from a clear acrylic material or polymeric material or a high tech metal alloy wherein a plurality of elongated elliptical and/or V-shaped grooves or indentations extend normal to the club head striking surface and are embedded in the crown, toe and sole of the club head. These grooves initiate from just behind the striking face or leading edge, and extend rearwardly toward the back of the club wood head. The grooves create a corresponding plurality of vortices during the golf swing which redirect air flow rearwardly away from the back of the club head, reducing drag and the wind resistance of the moving club head, which in turn increases thrust and the overall distance a golf ball is capable of travelling during a given shot.
