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 method for chemically etching a forged striking plate for a golf club to uniformly remove 0.002 inch to 0.015 inch of material therefrom. The forged striking plate is placed in an acidic bath to uniformly remove material from all surfaces of the striking plate. The forging process, conducted prior to etching, involves multiple heating and pressing of a metal bar to obtain a final face member configuration. The heating of the metal bar is performed at temperatures below 1000° C. for less than twenty minutes. The final face member configuration has a striking plate with regions of variable thickness. The metal bar is preferably composed of a forged titanium material.
