This invention relates to a category of golf clubs ranging from the driver to a seven wood, and ranging from a one iron to high lofted sand wedges. Each club within this category of golf clubs will provide superior playing characteristics compared to prior art golf clubs because of the lower axial inertia exhibited by the club heads of the present invention. For this invention, lower axial inertia is defined as lower rotational inertia about the club shaft longitudinal axis. The lower axial inertia is achieved by a reduction of the club head center of gravity to club shaft centerline distance when compared to a prior art club head. To achieve said reduction of the club head center of gravity to club shaft centerline distance, the present invention will utilize a special club head heel-sole-toe weighting configuration and a special method of hosel to club head heel attachment. A dictum of golf technique is that the club face should remain parallel and on the swing plane except near the impact point if the desired delayed hit is to be achieved. This means that the golfer must rapidly rotate the club shaft 90 degrees about its longitudinal axis in approximately 58 milliseconds just prior to impact. The low axial inertia club head of the present invention will facilitate the golfer in achieving the desired delayed hit. |
