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.

Abstract: A mallet style golf club with a novel head design consists of solid materials laminated or inlaid horizontally to yield a single surface alignment aid on the surface that strikes the golf ball (the front face/face). Optional alignment markings on the top surface of the club, centered over the point on the face where there is minimal torque when the head strikes the golf ball (“sweet spot”), combine with the single surface alignment aid on the face to form a single surface two-dimensional alignment system. An inlaid or laminated line on the circumference of the mallet joins the inlaid or laminated horizontal line on the front face to form a visually perceived 360 degree, three dimensional alignment aid.

Abstract: A golf putter with two reference lines on the top of the putter head and hosel and a reference indicator placed on the putter head below the hosel, all of which improves putting accuracy. The invention aids the golfer in positioning the golf ball in reference to the center of the face of the putter and properly positions the golfer's head and eyes directly above the putter. If the golfer's head and eyes are properly positioned over the putter, the reference lines on top of the putter and hosel will appear to be continuous and the reference indicator is not visible. However, if the golfer's head and eyes are not properly positioned above the putter, the reference lines appear to be discontinuous and/or the reference indicator is seen by the golfer.
