Abstract
Abstract A putter is disclosed having a beveled portion (16, 16') on the face (13, 13') of its club head (10, 10') to leave a straight line of intersection (17, 17') that can be viewed for use as a reference even with the club head tilted forward while addressing a ball, and which, as viewed by the golfer, appears to be horizontal when either the toe or heel portion of the club is raised up from the putting surface.
