Abstract: A method (500) for fitting a golf club to a golfer is disclosed herein. The method includes having a golfer hit a test golf club. If the test golf club is preferred, a final golf club is formed that matches the test golf club. Preferably, the final golf club matches the following parameters of the test golf club: volume, mass, mass location, inertial values, center of gravity location, material composition and shape. In a preferred embodiment, a test golf club with an interchangeable shaft is utilized with the method.

Abstract: A golf club having a club head with a striking plate having a thickness in the range of 0.010 to 0.250 inch is disclosed herein. The club head may be composed of three pieces, a face, a sole and a crown. Each of the pieces may be composed of a titanium material. The striking plate of the club head may have an aspect ratio less than 1.7. The striking plate may also have concentric regions of thickness with the thickness portion in the center. The club head may be composed of a titanium material, have a volume in the range of 175 cubic centimeters to 400 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a striking plate surface area in the range of 4.00 square inches to 7.50 square inches. The golf club head may also have a coefficient of restitution greater than 0.8 under test conditions such as the USGA test conditions specified pursuant to Rule 4-1e, Appendix II, of the Rules of Golf for 1998-1999.

Abstract: A putter (100) having a club head (20) having a central aperture (32) with a rearward center of gravity is disclosed herein. The club head (20) has a body (22) that is preferably composed of stainless steel. The body (22) has a face portion (24), a crown portion (26), a sole portion (28) and an aft-mass portion (30). The face portion (24), the crown portion (26), the sole portion (28) and the aft-mass portion (30) define the central aperture (32). The crown portion (26) extends rearward from the face portion (24) over the aft-mass portion (30). The central aperture (32) separates the crown portion (26) from the sole portion (28) and the face portion (24) from the aft-mass portion (30). The crown portion (26) has an alignment means (40) thereon for aiming a golf ball during putting. The putter has novel inertial properties.
