A blade bayonet is a type of weapon attachment that combines a knife or sword blade with a firearm, typically a rifle. It is designed to be mounted on the barrel of the gun, allowing the user to engage in close combat when necessary. Blade bayonets have been used in various military conflicts throughout history, enhancing the versatility of soldiers in battle. These bayonets often feature a sharp edge for slashing and stabbing, making them effective in hand-to-hand combat. Commonly associated with firearms like the M16 or Lee-Enfield, blade bayonets serve both as a tool for utility and a weapon for defense.
