Abstract
A golf putter head having a generally disk like shape with top and bottom surfaces substantially circular in shape, a rounded rear surface and a front surface being flattened thereby providing a face for striking a golf ball. The width of this face being approximately one third the width of the putter head. The putter head having a center of gravity positioned behind the face of the putter head at a distance of approximately one half the putter head length and an alignment stripe on its top surface. The unique shape of this putter head, alignment stripe, size and position of the putter head face, and location of the putter head center of gravity allows the putter head to: (1) improve and simplify the pre-putt alignment procedure, (2) consistently impact the golf ball on "sweet spot" of the putter head face thereby eliminating weak and ineffective putts, (3) have a shorter more controlled putter head backswing with a resulting high percentage of positive contact with the golf ball, and (4) eliminate putter head twist when impacting the golf ball thereby reducing misdirected putts.
