The Cat-O'-Nine-Tails is a type of whip traditionally made of nine knotted cords or thongs attached to a handle. It was historically used as a tool for punishment, particularly in naval settings, where it served as a means of discipline for sailors. The design allows for multiple strikes with a single swing, increasing its effectiveness. This whip has a long history, dating back to the 17th century, and is often associated with maritime culture. While it is no longer commonly used for punishment, the Cat-O'-Nine-Tails remains a symbol of authority and discipline in various contexts, including literature and popular culture.
