Legal answer
Possess brass knuckles in United States: legal status
The United States does not have one nationwide brass-knuckles rule. Official state sources show state-dependent regulation: California criminalizes manufacturing, importing, keeping for sale, offering for sale, giving, lending, or possessing metal knuckles, while Massachusetts punishes carrying metallic knuckles on the person or under control in a vehicle without legal authorization.
