Abstract
Abstract A golf putter especially adapted to provide training and practice in developing an accurate and precise swing and accuracy in engaging a golf ball by means of a putter head having a spherical contour on one face for putting training and in addition providing a flat putting surface on the opposite face of the club for practice and/or normal use. At the same time the putter is designed to be interchangeable for left or right hand use by providing a downward taper at each side of the club head. The flat putting surface may be formed with a transparent material to permit the insertion of informational matter.
