20100124999 | Asymmetrically shaped golf ball, method of manufacture, and method of use - An asymmetrically shaped golf ball that can be used to practice putting is disclosed. By way of a brief summary, the asymmetrically shaped golf ball has a “long axis” and a “short axis”, such that when placed with its “long axis” in a horizontal position, it will roll without a wobble only if pushed in line with the short axis. If pushed by even a few degrees off “center” the ball takes a wobbly path and the error in the golfer's putting stroke becomes obvious. | 05-20-2010 |
