Are Brass Knuckles Legal? What to Know Before You Buy

Brass knuckles might look simple, but figuring out whether they're legal is anything but. In some states, you can own them without any issues. In others, just having them in your bag could land you in trouble. The laws are all over the place, and they're not always easy to find or understand.

If you're thinking about buying a pair or just curious about how the laws work where you live, you're in the right place. This guide will walk you through the basics, explain why the rules vary so much, and help you figure out how to check your state's laws. We're not lawyers, and this isn't legal advice, but we'll show you where to look so you can get the facts for yourself.

Why Are Brass Knuckle Laws So Different from State to State?

Brass knuckles are handled differently across the country because states have the power to define and regulate weapons in their own way. What one state sees as a self-defense tool, another might classify as a dangerous weapon. The way they're treated in the law often depends on things like local crime rates, how the item is used, and whether it's viewed more as a threat than a means of protection.

In some places, the law focuses on how the knuckles are carried or whether they're concealed. In others, just owning a pair, regardless of how you store or use them, can be a crime. A few states even ban them outright, including versions made from plastic or polymer.

Because of these differences, it's important not to assume that what's legal in one state will be legal in another. That's why checking the laws where you live is always the safest move.

How to Check If Brass Knuckles Are Legal in Your State

The easiest and most reliable way to check brass knuckle laws is to visit your state's official government website. Look for the section that covers criminal codes, weapons laws, or self-defense statutes. These sites usually have searchable databases where you can type in terms like "brass knuckles," "metal knuckles," or "prohibited weapons."

If you're not sure where to start, try searching something on the search engines for something like "brass knuckles site:.gov California" (but change the State to your State). That will usually bring up the most relevant official pages. Just be careful to avoid relying on blogs, forums, or outdated articles, since laws can change and unofficial sources often get the details wrong.

For convenience, we've listed links to government websites for all 50 states later in this article. These links take you straight to the legal codes or enforcement pages so you can find the most up-to-date information for your area.

What to Do If You're Not Sure About the Law

If you're having trouble finding clear information about brass knuckle laws in your area, it's always best to ask someone who knows the legal system. Contacting your local police department, sheriff's office, or state attorney general's office can help you get the answers you need without guessing or risking a legal issue.

You can also talk to a criminal defense attorney in your area if you're especially concerned. While most people won't need to take it that far, a quick phone call or email to a law enforcement agency is usually enough to clarify what's allowed and what isn't.

Even if brass knuckles are legal where you live, there may be rules about how you can carry them or what materials are allowed. Some states only allow them in the home, while others treat them the same as firearms or knives. When in doubt, get it in writing from a legitimate source before making a purchase.

Can I Travel with Brass Knuckles Between States?

Traveling with brass knuckles can be risky, even if they're legal in your home state. Some states may allow them, while others can charge you with a crime just for having them in your car or luggage. Even if you're just passing through, local laws still apply once you cross state lines.

If you plan to travel with brass knuckles, it's a good idea to research the laws in every state on your route. What's legal in one place might not be in the next, and "I didn't know" usually isn't a valid excuse in court. When in doubt, leave them at home or contact law enforcement in the states you're passing through to double-check.

Are Plastic or Carbon Fiber Brass Knuckles Legal?

It depends on where you live. Some people assume plastic or carbon fiber brass knuckles are legal because they're not made of metal, but that's not always true. Many states define brass knuckles based on their shape or intended use, not just the material. That means a plastic or polymer version can still be considered illegal under the same laws that apply to metal knuckles.

In fact, some states have specific language that bans any object designed to fit over the knuckles and enhance striking power, regardless of what it's made from. So even lightweight, non-metal versions can get you into legal trouble if local laws are strict.

Always check your state's definition of prohibited weapons before buying or carrying any kind of knuckle duster, even if it seems harmless.

Is It Legal to Carry Brass Knuckles for Self Defense?

In some states, yes. In others, absolutely not. Carrying brass knuckles for self defense is legal in a handful of states, often with restrictions on how they're carried or whether they're concealed. But many states still consider them illegal weapons, no matter the reason you're carrying them.

Even if ownership is allowed, the law may still prohibit carrying them in public or using them in any kind of confrontation. In states where they're considered dangerous weapons, just having them in your pocket could be enough to get arrested.

If you're looking for a legal self-defense tool, make sure brass knuckles are permitted in your area for carry. Don't assume home ownership means you can bring them anywhere. Always check whether they need to be stored a certain way or declared to law enforcement if questioned.

Can I Keep Brass Knuckles in My Home if I Don't Carry Them?

In some states, yes. In others, even owning them at home is illegal. The law doesn't always make a distinction between carrying and simply possessing brass knuckles, so it's important to check your state's specific rules before buying a pair. This is true even if you plan to leave them in a drawer and never take them outside.

Some states do allow you to own brass knuckles as long as you don't carry them in public or use them to threaten anyone. Others classify them as prohibited weapons, meaning you could face charges just for having them at home. Always verify with an official source before assuming they're legal to keep, even for personal protection or as part of a collection.

Will TSA Take My Brass Knuckles If I Check Them in My Luggage?

Yes, TSA can confiscate brass knuckles-even if they're in your checked luggage. According to TSA rules, brass knuckles are considered prohibited items and are not allowed in carry-on bags under any circumstances. In checked bags, the rules are less clear, and it often depends on the discretion of TSA agents and airport security.

Even if you get them past TSA, brass knuckles may still be illegal in the state you're flying to or from. That means you could run into trouble with local law enforcement once your luggage is inspected, or if you are searched at any point during travel.

To stay safe, it's best not to fly with brass knuckles at all. If you do, make sure to check both TSA policies and state laws at your destination before packing them in your luggage.
