Abstract

A golf club head includes a heel, a toe, a level golf ball striking face extending from the heel to the toe and including a top edge and a bottom edge, and a patterned striking surface covering the level golf ball striking face extending to the heel, the toe, the top and the bottom edge. The patterned striking surface includes a plurality of generally pyramidal shaped extensions protruding from the level golf ball striking face, each of the pyramidal shaped extensions including a generally square base, four side walls and a top surface, each of the side walls extending outwardly a height H and at an angle Ω, the angle Ω being approximately equal to 60 degrees, from the golf ball striking face and the base, the center of the top surface of any pyramidal shaped extensions being separated from the centers of the top surfaces of all neighboring pyramidal shaped extensions by a width W.

Claims (10)

1. A golf club head comprising; a heel: a toe; a level golf ball striking face, said golf ball striking face extending from said heel to said toe and including a top edge and a bottom edge; a patterned striking surface covering said level golf ball striking face extending to said heel, said toe, said top edge and said bottom edge; and a plurality of generally pyramidal shaped extensions protruding from said level golf ball striking face, said patterned striking surface being comprised of said pyramidal shaped extensions, each of said pyramidal shaped extensions including a generally square base, four side walls and a top surface, each of said side walls extending outwardly a height H and at an angle Ω said angle Ω being approximately equal to 60 degrees, from said golf ball striking face and said base, the center of said top surface of any said pyramidal shaped extensions being separated from the centers of said top surfaces of all neighboring said pyramidal shaped extensions by a width W; wherein said height H is approximately equal to 0.019 inches; and wherein said width W is approximately equal to 0.050 inches.

2. The golf club head as recited in claim 1 , wherein said top surface is generally flat.
