发明名称 Golf club head with alignment markings
摘要 A golf club putter having an alignment pattern is disclosed herein. The alignment pattern has first and second long lines that approach each other as they extend from an aft region of the putter to a front region of the putter and, when the putter is properly aligned with a golf ball, create an optical illusion of convergence of said lines at or near a center of the golf ball without actually intersecting.
