<p>A golf club wherein in one embodiment the club head (50) is preferably molded from a clear acrylic material or polymeric material or a high tech metal alloy wherein a plurality of elongated elliptical or v-shaped gently flaring grooves or indentations (11, 12) extend normal to the striking surface (17) and are embedded in at least the crown (19) and sole (26) of the club head (50). These grooves (11, 12) may be present in the toe surface (16) in larger club heads, such as drivers. These grooves (11, 12) initiate from just behind the striking surface (17) or leading edge and extend rearwardly toward the back (20) of the club wood head (50). The grooves (11, 12) create a corresponding plurality of vortices during the golf swing which redirect and accelerate air flow rearwardly away from the back (20) of the club head (50), reducing wind resistance and eliminating induced drag of the moving club head (50), thereby increasing thrust which in turn increases the overall distance that a golf ball is capable of traveling during a given shot. In one embodiment of the invention, a metal housing (352) or shell is provided with an acrylic insert to achieve increased performance and durability.</p> |
