Abstract: The putter according to the invention comprises a putter head having a forward-facing striking surface, a heel, a toe, a top surface and a rear alignment section. The rear alignment section comprises one or more elongated indicator bars of uniform width that project backwards and that are arranged perpendicularly to the striking surface at a first upper level. Arranged at a second, lower level is a corresponding number of elongated warning strips of a contrasting color, each warning strip having approximately the same width as, and being arranged in vertical alignment with, its corresponding elongated indicator bar.

Abstract: A putter head having a forward-facing striking surface, a heel, a toe, a top surface and a rearward-facing, elongated tail section. The elongated tail section has vertical side walls, into each of which is machined an elliptical track or groove along the inside surface. The elliptical tracks are spaced from each other at a width slightly less than the diameter of a golf ball, and are machined into the sidewalls at a predetermined angle of incidence such that, when viewed from directly overhead, the tracks will be perceived by the user as two parallel lines. If the user's eyes are not directly in line with the plane extending vertically from the centerline, then one of the tracks will increasingly disappear behind its respective sidewall, while the opposite track will appear to become increasingly curved, as the degree of misalignment increases. The putter thus provides a means of alignment that improves putting accuracy.
