ABSTRACT:
An improved ferrule of a billiard/pool cue includes a generally cylindrical body with an open end and an opposed closed end. An interior bore is formed in the body and extends inward from the open end of the body for a predetermined distance toward the closed end of the body. An isolated hollow room is formed in the body and located between the inner end of the bore and the closed end of the body. The ferrule is attached to a shaft of a billiard/pool cue by means of a tenon formed on the shaft. Whereby the ferrule can tightly engage with the shaft of the cue and in the same time absorb the impact forces generated during the impact of the cue on a ball.
