How each wears

Solid brass, mirror or antique, wears into itself; there is nothing to chip. Black steel is the most forgiving coated finish. Chrome marks but does not chip. Plated colors on alloy (gold, rainbow, copper, pink, purple) wear through at the finger holes and edges with handling; graphics wear the same way. For a piece that will be handled, choose solid brass or black steel; for display, any finish.

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.
