What "metal" means

Zinc alloy or aluminum with a plated or painted finish. Light, inexpensive, and the material that takes gold, rainbow, copper, pink and purple finishes. Not solid brass; the material field on each product says so.

Buckle knuckles

A belt-buckle knuckle has a bar on the back that hooks a belt. Most buyers wear them; the buckle is a real buckle. Paperweights are the same castings without the bar.

Knuckles are regulated very differently from state to state and city to city, including possession, and are sold here as paperweights and collectibles. This page is not legal advice; read the state-by-state brass knuckles guide on Self Defense Supply, which cites the statutes, before ordering.

Frequently asked questions

Are belt buckle knuckles real knuckles?

They are cast alloy knuckle shapes with a buckle bar, sold as buckles and paperweights.

What is the cheapest knuckle piece?

About $7 for a paperweight or buckle.

Do the finishes wear?

Plated finishes wear at contact points; gold and rainbow more visibly than black.
