ABSTRACT:
The present invention is an improved putter that combines several features to provide a balanced putter, which assists a player in perfecting a putt stroke during practice and repeating it with the same club during play. The shaft is attached to the clubhead such that it can swivel from a practice configuration to a play configuration. The clubhead has tapered top and bottom surfaces such that the angle of the shaft relative to the sole of the putter is no more than 80 degrees. The clubhead has a playing surface on one face that is parabolic and can be flat in the extreme. The clubhead has a practice surface on the other face that is curved, preferably elliptical, to assist the golfer in learning the proper stroke. The putter conforms to the Rules of Golf so that the player does not have to change clubs between practice and play. The club may be used for either a right- or left-handed stroke.
