Abstract

Abstract The golf putter head includes a planar bottom and a vertical slot alignable with a lower angled painted surface to insure proper positioning of the eyes and head when setting up and executing a putt. The vertical slot and the line which one sees through it from the brightly painted surface is perpendicular to the face of the putter in the approximate center of the striking face. This line when set up with the line of the putt squares the face of the putter with the line of the putt. Thus, by grounding the club on its essentially flat bottomed surface, positioning one's head to see the line on the fluorescent surface, aligning the viewed line to the line of the putt, positioning one's body parallel to both lines, and swinging the club down the putt line, it is possible to strike almost all putts with the striking face square to the line of the putt. An alternate embodiment in place of the slot provides a single or a series of vertical holes on a line perpendicular to the putter striking face.
