A telescopic baton works by using a series of cylindrical shafts that can be extended and retracted. When collapsed, the baton is compact and easy to carry, but when extended, it becomes a long, rigid weapon. The baton is typically extended by a quick flick of the wrist, which causes the inner shafts to slide out and lock into place. To retract the baton, a button or lever is usually pressed to release the locking mechanism, allowing the shafts to slide back into the handle. This design allows for easy deployment and concealment of the baton, making it a popular choice for law enforcement and self-defense. **
