Arizona has some of the most lenient weapon laws in the country. That includes brass knuckles. But here’s the thing: where you live in Arizona matters a lot. Your city could have rules that are totally different from state law.
This guide breaks it all down. You’ll learn what’s legal, what’s not, and where things get complicated fast.
What Are Brass Knuckles?
Brass knuckles are handheld weapons. They fit over your fingers and are designed to make a punch much more powerful. They can be made of metal, hard plastic, or other solid materials.
Some people buy them for self-defense. Others collect them. But regardless of why you have them, Arizona law pays close attention to how and where you use them.
Pretty straightforward so far, right? Now here’s where things get layered.
Are Brass Knuckles Legal in Arizona?
Yes, adults can generally own and carry brass knuckles in Arizona. The state does not have a total ban on them for adults. No special permit is required either.
But wait. This is where your city comes in. Local laws can be stricter than state law. And some Arizona cities have gone much further than the state on this issue.
Wondering if your city has its own rules? Keep reading. This part is important.
Arizona State Law
Under Arizona law, brass knuckles have historically been listed as a “prohibited weapon.” That sounds scary. But the state’s weapon laws are complicated.
Under Arizona Revised Statutes (ARS) Section 13-3102, carrying a concealed deadly weapon is only illegal if you are under 21 years old. Adults 21 and over can carry many weapons, including brass knuckles, without a permit in most cases.
The key word here is “use.” Owning them is one thing. Using them to hurt someone is a completely different story. If you injure someone with brass knuckles, courts will likely treat them as a deadly weapon. That means felony assault charges are possible. That’s serious.
Think of it like this: a baseball bat is legal to own, but swinging it at someone is a crime. Same idea here.
The Under-21 Rule
Here’s a big one. If you are under 21 years old in Arizona, the rules change significantly.
State law says that people under 21 cannot legally carry a concealed deadly weapon. Brass knuckles can fall under that category. Carrying them hidden on your person when you’re under 21 could lead to a class 4 felony charge.
A class 4 felony is no joke. It can mean prison time, heavy fines, and a criminal record that follows you for life. That’s way more serious than most people expect.
Honestly, this is the part most people miss. They assume it only matters if you use them. It doesn’t.
City Laws: This Is Where It Gets Really Important
Okay, pause. Read this carefully.
Even if state law allows brass knuckles for adults, your city might not. Arizona cities have passed their own local rules. Some are much stricter.
Chandler: In June 2024, Chandler passed a law making it illegal for anyone under 18 to own or purchase brass knuckles. Businesses must also verify that buyers are at least 18 years old. Breaking this law is a class 1 misdemeanor. That can mean fines up to $2,500, up to six months in jail, and three years of probation.
Gilbert: The Town of Gilbert has a similar rule. Anyone under 18 is banned from purchasing or possessing brass knuckles there too.
Tempe: Tempe goes further than both. Tempe bans brass knuckles for everyone. Adults included. Selling or giving brass knuckles to anyone under 18 is also prohibited.
Phoenix: Phoenix has restrictions in place as well. Many sources indicate brass knuckles are treated as illegal for both minors and adults in Phoenix.
You’re not alone if this is confusing. Most people don’t realize how different the rules can be just a few miles apart.
Why Cities Started Acting
Here’s a quick bit of background. A friend asked me about this recently. I looked it up and found the story behind these local laws.
In the East Valley area of Arizona, a group called the “Gilbert Goons” was linked to a series of violent teen attacks. Brass knuckles were reportedly used in those assaults. One attack even resulted in a teen’s death.
That sparked action. Chandler and Gilbert responded with new local ordinances in 2024. The goal was to keep brass knuckles out of the hands of minors.
At the state level, lawmakers tried to pass a statewide bill in 2025 that would ban brass knuckles for minors across all of Arizona. It failed. The bill did not get enough votes in the Senate.
So right now, the rules vary significantly depending on where you are in the state.
Where You Absolutely Cannot Carry Them
Even if brass knuckles are technically legal where you live, there are places where you can never bring them.
Schools are off-limits. Possessing any deadly weapon on school grounds in Arizona is a class 1 misdemeanor under ARS 13-3102.
Government buildings are also restricted. Courts, police stations, and other public government facilities prohibit weapons. Bring them into these spaces and you could face immediate charges.
Federal property is another no-go zone entirely. National parks, federal courthouses, and airports all fall under federal law. It does not matter what Arizona state or city law says. Bringing brass knuckles onto federal property is a federal offense.
Private property is also a factor. If a business or property owner says no weapons, you need to respect that rule too.
Penalties at a Glance
Here is how serious these charges can get, depending on the situation.
Using brass knuckles to injure someone can result in felony assault charges. A class 4 felony in Arizona can bring 1.5 to 3 years in prison for a first offense. Aggravated assault charges can go even higher.
Under-21 concealed carry can also be a class 4 felony under state law.
Possession on school grounds is a class 1 misdemeanor. That means up to six months in jail and fines up to $2,500.
Violating Chandler’s or Gilbert’s local ordinance is also a class 1 misdemeanor. Same penalties: up to six months in jail, fines up to $2,500, and three years of probation.
Less severe than a felony, but a misdemeanor is still no joke. It shows up on your record.
Special Circumstances
There are a few situations worth knowing about.
Self-defense matters in court. If you used brass knuckles to protect yourself from an immediate threat, Arizona’s self-defense laws under ARS 13-404 could be relevant. The force must be necessary and proportional to the threat. You still may face charges, but self-defense can be raised as a defense.
Materials don’t change much. Whether your brass knuckles are actual brass, aluminum, or hard plastic, they can still be treated the same under the law. The definition in proposed state legislation describes them as any device made of metal, plastic, or hard material designed to fit over the knuckles.
Minors and parents should both pay attention. Some local ordinances can hold businesses and even parents accountable if their children possess these weapons.
What You Should Do
Stay with me here. This is the practical part.
First, look up the specific laws for your city. Arizona state law is one thing, but your local ordinance may be stricter. The city websites for Chandler, Gilbert, Tempe, and Phoenix have information on their local weapon rules.
Second, if you are under 21, be extra careful. The risks are much higher for you under state law.
Third, never bring brass knuckles to a school, courthouse, government building, or any posted restricted area. There are no exceptions for these locations.
Fourth, if you are facing any charges related to brass knuckles, talk to a lawyer right away. Arizona weapon laws are complicated. A local attorney who handles criminal defense can give you advice specific to your situation.
Trust me, that call is worth it.

Do I need a permit to carry brass knuckles in Arizona?

Final Thoughts
Arizona is one of the more permissive states when it comes to brass knuckles. But “permissive state” does not mean “anything goes.” Your city, your age, and where you carry them all make a huge difference.
The bottom line: if you are over 21, check your local city law. If you are under 21, the risks under state law alone are serious. And no matter what, keep them away from schools, government buildings, and federal property.
When in doubt, talk to a lawyer. The laws in this area are genuinely complicated and changing. Staying informed is the smartest move you can make.
