  • Method of aligning a golf ball with a golf club and golf club with alignment indicia
    Patent number: 6379258
    Abstract: A golf club with alignment indicia and method of use of the same. The golf club includes a shaft having a gripping end and a remote end. A club head is secured to the remote end of the shaft. The club head has a top and a striking face. The alignment indicia are in the form of a first straight line and a second straight line positioned in spaced apart relation on the top of the club head. The first straight line and the second straight line diverge as they approach the striking face. The first straight line is closer to the shaft than the second straight line. By selecting the first straight line or the second straight line for alignment, the striking face of the golf club is moved to an open or closed position to aid in intentional placement of the golf ball from the left or right toward a selected target.
