Abstract
Abstract A putter head comprising a top portion formed with a hosel for coupling the head to a shaft; a bottom portion formed with a sole for positioning the putter head in a ball-striking orientation on a putting green; and a ball-striking face located therebetween. The ball-striking face is arcuate in cross-sectional shape curved about an axis located in a horizontal plane between the top portion and the bottom portion. The radius of curvature of the ball-striking face is essentially 0.84 inches. Both the horizontal plane and the axis of the ball-striking face are located essentially 0.84 inches from the sole. The curved face extends downwardly from at least the horizontal plane.
