SHAPE OF GOLF PUTTER FACE

摘要

PROBLEM TO BE SOLVED: To eliminate a no-rolling state of a ball in putting in golf. SOLUTION: For the shape of this golf putter face surface 2, the central part of the putter face surface 2 is made hollow, and a contact point between a ball and the face surface is moved to a location which is higher than the central point of the ball, and thus, an advancing rolling is immediately imparted to the ball at the time when the ball is hit, and the stability in the directionality is realized.
