A golf putter including a head which has detachably fastened to the body thereof a face plate provided with a plurality of striking surfaces which are selectably and interchangeably oriented by a player to a forward facing use position, the striking surfaces each having different ball-impacting characteristics, e.g., rebound factor, hardness, and/or frictional characteristics. In one embodiment, the face plate has flat front and rear parallel surfaces in which are fitted inserts with different ball-impacting characteristics, the face plate being attachable conformally to the front face of a putter head body with a selected insert in a forward-facing use position by a pair of screws inserted through holes in the face plate in opposite sides of the inserts and tightened into a pair of aligned threaded bores which extend perpendicular into the front face of the putter head body. In another embodiment, the face plate fits conformally into a recess provided in the front face of a putter head body, the recess being of sufficient depth to hold a single, double insert plate, or deeper to accommodate a pair of thin, rectangular cross-section double-insert face plates, or a square cross-section, quadruple-insert face plate in which two pairs of inserts are mounted in four lateral faces of the face plate.
