Material decides everything
| Material | Weight | Price here | Buy it for |
|---|---|---|---|
| Solid brass | 10 to 14 oz | $16 to $21 | The real thing; collectors; patina |
| Steel | 10 to 12 oz | $7 to $14 | Same weight as brass, less money, black or chrome |
| Zinc alloy / aluminum ("metal") | 4 to 7 oz | $7 to $9 | Belt buckles, paperweights, colors and graphics |
If the listing says "brass knuckles" but the material field says metal, it is a zinc or aluminum piece with a brass-colored finish. That is fine for a buckle or a display piece; it is not solid brass, and this site labels the difference on every product.
Fit
Standard four-finger frames fit most adult hands; the XL frame is cut wider; compact frames suit small hands. Heavy pieces in a loose frame twist, so if you are between sizes choose the smaller frame in a light alloy or the XL only in a heavy material. Detail: brass knuckles for small hands and big hands.
Finish
Mirror brass darkens to a patina; black steel hides wear; chrome shows fingerprints; gold, rainbow, copper, pink and purple finishes are plating on alloy and wear at the contact points. See brass knuckle finishes.
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.
