Abstract

This application involves the reform of the putting method. The main improvement is that the position of the ball has been changed to the left. The address is positioned deep under the bottom of the ball. Occasionally, the address is positioned at 30 cm away from the ball. The player takes a back swing looking at only the cup and hits the ball straight. As for the short and middle, the player takes a 1 to 2 cm back swing. As for the long, the player freely takes about 40 cm back. The sole of the head has changed into a two-sided one with a new sole. The axis of the new hitting style is shifted to near the bottom right of the stomach or above the right knees. The width of the blades of the putters and irons has been changed to 1 cm. The grooves on the blade of the irons are extended to the surface of the head. The flat surface below the lowest line of the grooves on the blade has been narrowed as much as possible to the limits of the Rules. A full-face side-saddle is introduced. To summarize, a golf club that is simplified, lightened and easily used has been made.
