Brass knuckles are a handheld metal weapon designed to fit over the knuckles and increase the force and injury caused by a punch. They are also known as knuckle dusters or knucks and are associated with concealed carry and unlawful violence in many jurisdictions. Canadian readers may encounter brass knuckles mainly in the context of weapons law and criminal justice, since the item is commonly treated as a prohibited or restricted weapon in many jurisdictions.

Design and use

Brass knuckles are designed to fit around the fingers and rest across the palm so a closed fist can deliver a harder blow. Definitions describe them as a metal weapon or cover worn over the knuckles to increase injury caused by striking.

Names and variants

The weapon is commonly called brass knuckles, knuckle dusters, knucks, or iron fists. Sources also note that modern examples may be made from materials other than brass.

Legal status

Brass knuckles are restricted or illegal in many jurisdictions because they are easily concealed and can be used as offensive weapons. Legal treatment differs by country and region, and some laws prohibit possession, carry, sale, or transfer. Specific legality depends on Canadian law and related provincial or federal rules, which should be checked separately.

Public perception

Brass knuckles are often associated with street violence and organized crime in popular descriptions. They are also sometimes sold or displayed as novelty or collector items, depending on local law.
