  • Patent number: 8371958
    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 ?, the angle ? 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.

  • Publication number: 20100222153
    Abstract: A golf putter head is provided that includes an upper plate and a base plate. The base plate further includes a striking surface. The mass of the putter head is distributed such that the mass of the upper plate is greater than the mass of the base plate, thereby positioning the center of gravity of the putter head above a centerline of said striking surface and an equator of a golf ball when the golf ball is positioned proximate to the striking surface of the golf putter head.
