A golf putter is provided which includes a golf club shaft having a first end and a putter head assembly. The putter head assembly includes a main body member, a front face portion and a back face portion. A recessed area is defined by the front face portion.

Several features are combined 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 clubhead is substantially symmetric around the shaft and 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 shaft is attached at the center of the clubhead, and the clubhead and shaft are arranged so that the center of gravity of the clubhead strikes the center of the golf ball. 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 a right- or left-handed stroke.
