A bayonet is a blade that can be attached to the muzzle of a firearm, typically a rifle, allowing the weapon to be used for close combat. It originated in the 17th century and was designed to turn a gun into a spear-like weapon. Bayonets are often used in military settings, providing soldiers with a versatile tool for both shooting and hand-to-hand fighting. Bayonets come in various designs, including the socket bayonet and the blade bayonet. They are usually made of steel and can be fixed or detachable. While their use has declined with the advent of modern warfare, bayonets remain a symbol of military tradition and are still used in some armed forces around the world.
