<p>PROBLEM TO BE SOLVED: To provide a putter head whose swing motion is prevented to make it easier to strike a ball with precision. SOLUTION: A golf putter is balanced for its center of gravity around a shaft 12 by setting the axis AL of the shaft 12 to pass the center C of a square defined by the center of gravity G of a putter head 13, the ball striking point H of a face 14, and the fixed point F of the shaft 12 on the head 13. Thus since the striking point of the face of the putter head is set on the shaft axis, it is made possible to strike a ball with a sense of integrity between the ball and the shaft.</p> |
