Abstract: A billiard cue stick which is typically constructed of aluminum or other lightweight metal and can be fitted with removable weights for imparting a selected weight and balance to the cue stick. In a preferred embodiment, the billiard cue stick is characterized by a shaft segment which is removably attached to a hollow butt segment. The extending front end of the shaft segment is terminated by a removable shaft cue tip for striking a cue ball in a game of billiards or pool. The butt segment includes a handle fitted with an elongated weight slot or multiple weight openings for removably receiving a selected number of spherical weights. The butt segment is further characterized by multiple, adjacent, longitudinal splines typically fitted with rubber or plastic strips. The front end of the butt segment, removably attached to the rear end of the shaft segment, is fitted with a removable extra cue tip to facilitate replacing the removable shaft cue tip with the extra cue tip on the shaft segment, as needed.
