T-baton

A baton or truncheon is a roughly cylindrical club made of wood, rubber, plastic or metal. It is carried as a compliance tool and defensive weapon by law-enforcement officers, correctional staff, security guards and military personnel. In many cultures, they are highly symbolic of law enforcement and are rarely used with the intention to kill.

A truncheon or baton may be used in many ways as a weapon. It can be used defensively to block; offensively to strike, jab, or bludgeon; and it can aid in the application of armlocks. The usual striking or bludgeoning action is not produced by a simple and direct hit, as with an ordinary blunt object, but rather by bringing the arm down sharply while allowing the truncheon to pivot nearly freely forward and downward, so moving its tip much faster than its handle. Batons are also used for non-weapon purposes such as breaking windows to free individuals trapped in a vehicle, or turning out a suspect's pockets during a search (as a precaution against sharp objects).

Some criminals use batons as weapons because of their simple construction and easy concealment. The use or carrying of batons or improvised clubs by people other than law enforcement officers is restricted by law in many countries.

Other names for a baton are a truncheon, cosh, billystick, billy club, nightstick, or stick.

In the Victorian era, police in London carried truncheons about one-foot long called billy clubs. According to the Online Etymology Dictionary, this name is first recorded in 1848 as slang for a burglars' crowbar. The meaning "policeman's club" is first recorded 1856. The truncheon acted as the policeman's 'Warrant Card' as the Royal Crest attached to it indicated the policeman's authority. This was always removed when the equipment left official service (often with the person who used it). Earlier on the word was used in vulgar Latin (bastο—a stick helping walking, from basta—hold).

The Victorian original has since developed into the several varieties available today. The typical truncheon is a straight stick made from wood or a synthetic material, approximately 1.25 inches (32 mm) in diameter and 18–36 inches (460–910 mm) long, with a fluted handle to aid in gripping. Truncheons are often ornamented with their organizations' coats of arms. Longer truncheons are called "riot batons" because of their use in riot control. Truncheons probably developed as a marriage between the club or military mace and the staff of office/sceptre.
