Abstract: This invention provides golf putter training tools for training a golfer's putting stroke. These golf putter training tools assist a golfer in making the putting stroke flat and in a straight "sweeping" line. A wheel, attached to the putter body, is provided adjacent each end of the putter and constructed to roll when the proper putting motion is used. The wheels (provided either as a putter part or as an add-on) extend slightly below the bottom surface of the putter and may include sharp portions along their circumference to impede other than straight rolling.
