Abstract
A putter having a head with golf ball-centering indicia. The ball-centering indicia include a curvilinear reference which is tangent to the edge formed between the upper surface of the head and the ball-striking surface, or to a parallel line proximate the edge. The curvilinear reference has a radius of curvature which the substantially equal to the nominal radius of a golf ball and is subtended, with reference to the center of curvature by a center angle less than 180.degree. and preferably about 90.degree.. The ball-centering indicia further include a rectilinear reference formed, for example, by a pair of parallel segments positioned symmetrically on both sides of the normal to the tangent point, extending along the direction of the aiming axis. A parallax correction reference can also be provided which enables the golfer to ensure that the head of the putter is properly horizontally positioned about the aiming axis.
