Abstract
The present invention is to provide a billiard cue having an improved shaft. The shaft includes a wooden main shaft, an interior shaft, and an exterior coating. The wooden main shaft has a hollow core with a predetermined length extending along the direction of a longitudinal axis of the main shaft. The interior shaft is made of a material harder than the wooden main shaft and is tightly received in the hollow core of the main shaft. The exterior coating is made of a fiber composite material and is coated on the exterior periphery of the main shaft. Accordingly, the main shaft takes advantages of the wooden material and can prevent curvature and/or deformation by means of the interior shaft and the exterior coating.
