Brass Knuckles laws in Missouri
Missouri Revised Statutes (RSMo) 571.010 defines 'dangerous weapon' to include 'any weapon, device, instrument, material or substance, whether animate or inanimate, which in the manner it is used or is intended to be used is capable of producing death or serious physical injury.' While brass knuckles are not explicitly listed, they generally fall under this broad definition. RSMo 571.030, 'Unlawful use of weapons,' makes it a Class E felony to 'knowingly carry concealed upon or about his or her person a knife, a firearm, a blackjack, or any other weapon readily capable of lethal use.' Courts have interpreted 'any other weapon readily capable of lethal use' to include brass knuckles. Therefore, carrying brass knuckles concealed is illegal. Open carry, without unlawful intent, may not be explicitly prohibited, but their classification as a dangerous weapon means that any use or intent to use them unlawfully would result in severe penalties. The law aims to prevent their use in criminal activities rather than prohibiting their mere existence, making them a restricted item rather than an outright ban for all circumstances. Law enforcement officers and military personnel are typically exempt when acting in their official capacity.
