👉 A weapon is any object or tool designed for the purpose of inflicting physical harm or causing injury. Examples include firearms like pistols, rifles, and shotguns, which use gunpowder or electricity to propel projectiles at high speeds; melee weapons such as knives, swords, and fists, which are used for close combat; and non-lethal weapons like tasers, pepper spray, and batons, which are employed to subdue or deter without causing permanent harm. Each type of weapon serves a specific function in defense, hunting, self-protection, or law enforcement.
