Abstract: A hard rubber plate forms a striking surface that covers most of a front face of a body of a club head of a putter. The thickness of the plate prevents an uncovered edge of the front face from striking a golf ball. The front face has an arcuate shape that indicates a part of the striking surface that ideally strikes the golf ball. A sighting fin extends rearward from the front face. The fin has a horizontal sighting surface that provides sighting in a direction perpendicular to the striking surface. The body has a plurality of threaded holes wherein a screw is engaged to provide a desired weight and distribution of weight of the club head. When a mallet putter is oriented with its hosel extending vertically above its body, a bottom of the mallet putter's body slopes upward from its front face to a back of the body. Disadvantages of a large front to back length of a mallet putter are obviated by the upward slope.
