Abstract
An improved optical putter. The optical putter has a club head whose cross-section is characterized as having four active surfaces: a substantially flat surface for resting the club head upon the green in a first alignment position; a ball-addressing surface; a second, substantially flat, reflective surface for aligning the golf club in a second alignment position; and a substantially flat bottom surface that is substantially perpendicular to the ball-addressing surface. The reflective surface is a semi-circular wedge shape having a sighting line for guiding the golfer to position her or her head and stance. Depending upon the alignment position, the reflecting surface can face upwardly towards the eye of the golfer or towards the cup of the green.
