<p><P>PROBLEM TO BE SOLVED: To provide a putter precisely hitting a ball in the aimed direction. <P>SOLUTION: This golf putter comprises the club head whose plane shape is obliquely worked into a fan shape so that, for imaging an imaginary point on a line formed of a cup and the putter, sides 2 perpendicular to a face intersects with each other at 30 cm ahead of the hitting direction and plating workpieces or acrylic are embedded in parallel to the obliquely worked surfaces so as to easily watch the respective oblique lines; and a shaft whose cross sections of its end, its center and its tip are changed into circular, rectangular and circular respectively and which has elasticity so as to move the club head only in the hitting direction. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
