A generally rectangular body is provided of substantially square cross-sectional shape and the body includes a central longitudinal threaded bore formed therethrough with one end of the bore provided with a smooth diametrically enlarged counter bore opening end wise outwardly of one end of the body. One side of the body is relieved to define a flat mounting surface disposed in a chord plane of the counter bore and mounts a blade member therefrom including an elongated beveled sharpened edge projecting slightly into the counter bore. An abutment screw is threadingly received within the bore and projects at least slightly into the counter bore and may be adjusted to adjustably limit the amount a cue stick mounted tip may be telescoped into the counter bore. The counter bore is of a size to snugly but loosely receive a newly mounted cue tip therein and the body may be rotated about the longitudinal axis of the threaded bore relative to an associated cue stick in order to trim the enlarged outer peripheral portion of a newly installed cue tip from the latter so as to provide the cue tip with a cylindrical outer surface co-extensive with adjacent cylindrical outer surfaces of the cue stick.
