Brass Knuckle Laws in Minnesota (2026): The Complete Ban

Most people don’t realize how strict Minnesota is about brass knuckles. Like, seriously strict. If you’re thinking about buying a pair, carrying them, or even keeping them as a collectible, you need to know this. Minnesota doesn’t mess around with these laws.

Let me break down exactly what you need to know about brass knuckle laws in Minnesota.

What Are Brass Knuckles?

Brass knuckles are hand weapons that fit over your knuckles. They make your punch more powerful and focused. Think of them like a metal glove for your fist.

But here’s the thing. Minnesota law doesn’t just ban brass knuckles made of brass. The state calls them “metal knuckles” in the law. This means any material counts. Metal, plastic, wood, even those novelty ones. All illegal.

Sound strict? It gets stricter.

The Basic Law in Minnesota

Minnesota Statute 609.66 is the main law you need to know. This law puts brass knuckles in the dangerous weapons category. Under this statute, you cannot manufacture, transfer, or possess metal knuckles.

Let’s break that down into plain English.

Manufacturing means making them. If you’re crafting brass knuckles in your garage, that’s illegal. Transferring means selling, giving away, or trading them. Even gifting a pair to your buddy is against the law. Possessing means owning or carrying them. Having them at home, in your car, or on your person all count as possession.

Basically, if you touch brass knuckles in any way, you’re breaking the law in Minnesota.

Not sure what counts as a violation? Here’s the simple truth. Any connection to brass knuckles puts you at risk. The law covers everything from buying to selling to just having them around.

Are There Any Exceptions?

Hold on, this part is important.

Some states allow brass knuckles for collectors or museums. Minnesota used to have a collector exception in the law. But courts have made it clear that this exception is extremely narrow. You need to prove you’re running an actual museum or legitimate art collection that’s open to the public.

Honestly, this is the part most people miss. Just hanging brass knuckles on your wall doesn’t make you a collector in Minnesota’s eyes. The court looked at a case where someone claimed the collector defense. The guy had brass knuckles hanging in his house. The court said no way. He wasn’t a museum. He wasn’t displaying art for the public. He was just someone who owned brass knuckles.

So can you legally own brass knuckles in Minnesota as a collector?

Pretty much no. Unless you run an actual museum with public hours and everything, don’t count on this defense. Most people don’t realize how strict this rule is. They find out the hard way.

Don’t be one of them.

What About Self-Defense?

You’re not alone if you’re thinking about brass knuckles for self-defense. This confuses a lot of people. But Minnesota doesn’t care about your reason for having them.

Self-defense is not a valid excuse. The law bans possession regardless of intent. Even if you never plan to use them illegally, just having them is the crime.

Wait, it gets more complicated.

Minnesota does allow other self-defense tools. You can carry pepper spray. You can own certain knives. But brass knuckles? Totally off limits. The state sees them as weapons designed only to cause serious harm.

Penalties for Breaking the Law

Okay, pause. Read this carefully.

If you get caught with brass knuckles in Minnesota, you face criminal charges. The level of charge depends on where you get caught.

Regular possession is a misdemeanor. That means up to 90 days in jail and up to $1,000 in fine. That’s the minimum penalty you’re looking at.

Possession in certain zones bumps it up to a gross misdemeanor. These zones include school zones, park zones, and public housing zones. A gross misdemeanor means up to one year in jail and up to $3,000 in fine.

Makes sense, right? The state takes it more seriously when you have brass knuckles near schools or parks.

But there’s more you need to know. These penalties are just the maximum allowed by law. Judges have discretion within these limits. A first-time offender might get probation instead of jail time. But you’ll still have a criminal record.

Yep, that’s all it takes.

The Criminal Record Problem

Here’s where it gets really serious. A conviction stays on your record forever in Minnesota. No automatic removal. No expiration date. Forever.

This matters way more than most people think.

A criminal record affects your job prospects. Many employers run background checks. A weapons conviction can disqualify you from certain jobs. Security positions? Forget it. Jobs working with kids? Not happening. Even retail and service jobs might pass on you.

It affects housing too. Landlords often check criminal records. A weapons charge makes you look like a risk. You might get denied for apartments or rental homes.

Can you get it expunged?

Maybe. Minnesota allows expungement for misdemeanors after two years. For gross misdemeanors, you have to wait four years. But you can’t commit any other crimes during that waiting period. And certain offenses can’t be expunged at all.

Basically, the record follows you for a long time.

What Counts as Metal Knuckles?

Confused about the difference? Let me break it down.

Minnesota law says “metal knuckles.” But courts interpret this broadly. Any device that fits over the knuckles to make punches more dangerous counts. This includes traditional brass knuckles made of brass. But it also includes steel knuckles, aluminum knuckles, and iron knuckles.

Now, here’s where it gets interesting.

Some people try to get around the law with plastic or composite knuckles. They figure if it’s not metal, it’s not illegal. Wrong. Minnesota courts have said that even non-metal knuckle weapons can be considered dangerous weapons under a different part of the law.

So those plastic knuckle dusters you see online? Still risky in Minnesota. The state can charge you with possessing a dangerous weapon even if they’re not technically “metal” knuckles.

Don’t risk it.

Belt Buckles and Jewelry

Wondering if this applies to you?

Some companies sell belt buckles shaped like brass knuckles. Others sell jewelry items that look like knuckles. These fall into a gray area. If the item is clearly decorative and can’t actually be used as a weapon, you might be okay. But if it’s functional, you’re at risk.

Here’s the test. Can you actually put it on your fingers and use it as a weapon? If yes, it’s probably illegal. If it’s just a design on a belt buckle that you can’t remove and use, you’re probably fine.

Probably.

Honestly, Minnesota law enforcement might still give you trouble. Even if you eventually beat the charge, you’ll spend time and money on a lawyer. Is a brass knuckle belt buckle worth that hassle?

Most people would say no.

What to Do If You Already Own Brass Knuckles

So what happens if you already have brass knuckles at home?

You need to get rid of them. Seriously. Don’t just throw them in the trash though. That’s technically illegal disposal. You have a few options.

First, you can turn them in to local law enforcement. Most police departments will take unwanted weapons with no questions asked. Just call ahead and ask about their weapons disposal program. They’ll tell you how to do it safely and legally.

Second, you can destroy them yourself. Make sure they’re completely unusable. Then dispose of the pieces in regular trash. This eliminates any chance someone else finds and uses them.

Don’t try to sell them. Don’t give them away. Both of those are illegal transfers under Minnesota law.

Trust me, this works. It’s the safest way to handle the situation.

How Police Find Brass Knuckles

Let’s talk about how people actually get caught. Most brass knuckle charges don’t happen in isolation. Police typically find them during traffic stops or other investigations.

Here’s a common scenario. Officer pulls you over for a traffic violation. You consent to a vehicle search or the officer has probable cause. They find brass knuckles in your glove box or under the seat. Now you’re facing a weapons charge on top of whatever they stopped you for.

Another common situation involves domestic calls or disturbances. Police respond to your home for an unrelated issue. They see brass knuckles on display or in plain view. That can lead to charges.

Pretty straightforward. The best way to avoid charges is simple. Don’t have brass knuckles in the first place.

Real-World Consequences

This one’s probably the most important thing to understand. A brass knuckles charge affects more than just your criminal record. It can derail your entire life.

College students face disciplinary action from their schools. Many universities have weapons policies that go beyond state law. A conviction could get you suspended or expelled.

People with professional licenses face review boards. Teachers, nurses, lawyers, and other licensed professionals might lose their licenses over a weapons conviction.

Immigration status can be affected too. Non-citizens convicted of weapons offenses face potential deportation. Even legal permanent residents are at risk. The federal government takes a dim view of weapons crimes.

Custody battles get more complicated. If you’re involved in a custody dispute, a weapons charge gives ammunition to the other side. Family courts consider it evidence of poor judgment or danger to children.

Don’t worry, we’ll explain how to protect yourself.

Comparison with Other Weapons

Minnesota treats different weapons differently. Understanding these differences helps put brass knuckles laws in perspective.

Knives are generally legal in Minnesota. You can own most types of knives. The main exception is automatic switchblades. Those are illegal to manufacture, transfer, or possess. Just like brass knuckles.

Pepper spray is legal. You can carry it for self-defense. No permit required. The state recognizes it as a legitimate defensive tool that’s less likely to cause permanent harm.

Firearms are legal with proper licensing. Minnesota allows concealed carry with a permit. The state regulates guns heavily but doesn’t ban them outright.

Tasers and stun guns fall into a gray area. They’re legal to own for self-defense in your home. But carrying them in public might require a concealed carry permit.

Brass knuckles stand out as one of the few weapons with a complete ban. Less severe than a felony charge, but still no joke. The state just doesn’t want people having them at all.

Online Purchases and Minnesota Law

Here’s something many people don’t consider. You can find brass knuckles for sale online easily. Websites ship them to all 50 states. But just because you can buy them doesn’t mean you can legally own them in Minnesota.

Ordering brass knuckles online and having them shipped to Minnesota is illegal. The moment they arrive at your home, you’re in possession. That’s a crime. Some sellers claim they’re selling them as “paperweights” or “collectibles.” That doesn’t protect you under Minnesota law.

What if you buy them in another state?

Bringing them into Minnesota is still illegal. Some states allow brass knuckles. If you travel to one of those states and buy a pair, you can’t bring them home. Crossing the state line with brass knuckles makes you guilty of possession in Minnesota.

It’s actually not that complicated. Minnesota law applies to you when you’re in Minnesota. Period.

What About Keychains and Novelty Items?

This part can be tricky. Some stores sell cat-shaped keychains that fit over your knuckles. The pointy ears make them weapons. Are these illegal?

Minnesota courts would likely say yes. If the item fits over your knuckles and makes your punch more dangerous, it functions as metal knuckles or a dangerous weapon. The cute cat design doesn’t change what it is.

Same goes for those skull-shaped paperweights with finger holes. Or decorative items that happen to be knuckle-shaped. If they’re functional as weapons, they’re risky to own.

You’re not alone, this confuses a lot of people. The safe answer is to avoid anything that resembles brass knuckles and can actually be used as a weapon.

Getting Legal Help

Sound complicated? It’s actually pretty clear once you understand the law.

If you’ve been charged with a brass knuckles violation, you need a lawyer. This is not a DIY situation. A criminal defense attorney can help in several ways.

They can review the circumstances of your arrest. Maybe police violated your rights during a search. Maybe the item doesn’t actually qualify as metal knuckles under Minnesota law. A lawyer spots these issues.

They can negotiate with prosecutors. First-time offenders might get reduced charges or alternative sentencing. Your lawyer can push for these options.

They can represent you in court. If your case goes to trial, you need someone who knows Minnesota weapons laws inside and out.

Most criminal defense attorneys offer free consultations. Use them. Find out what you’re facing and what your options are.

Marijuana Laws as a Comparison

Want to understand how seriously Minnesota takes brass knuckles? Compare them to marijuana laws.

Minnesota legalized recreational marijuana recently. Possession of small amounts is now perfectly legal. The state decided marijuana wasn’t dangerous enough to ban.

But brass knuckles? Still completely illegal. No amount is okay. No exceptions for personal use. The state views them as inherently dangerous weapons with no legitimate purpose.

This shows you where Minnesota’s priorities are. They’ll let you smoke marijuana legally. But don’t even think about owning brass knuckles.

Interstate Travel Considerations

Planning a road trip? Be aware of brass knuckle laws if you’re traveling through Minnesota.

Let’s say you live in a state where brass knuckles are legal. You own a pair legally at home. You’re driving through Minnesota to get somewhere else. If police find the brass knuckles in your car during a traffic stop in Minnesota, you can be charged.

Minnesota law applies to everyone in Minnesota. Your home state’s laws don’t matter. Out-of-state visitors get charged just like Minnesota residents.

The solution is simple. Don’t bring brass knuckles into Minnesota. Leave them at home or ship them separately if you’re moving.

Now you know the basics. Stay informed, stay safe, and when in doubt, leave the brass knuckles at home. Or better yet, don’t own them at all if you live in Minnesota.

Frequently Asked Questions

Can I own brass knuckles in my home if I don’t carry them in public?

No. Minnesota law bans possession entirely. Having them at home is still illegal. There’s no exception for private property.

What if I bought brass knuckles before the law was passed?

The law has been around for decades. There’s no grandfather clause. Even if you owned them legally years ago, they’re illegal now.

Can I transport brass knuckles through Minnesota if I’m moving to another state?

Technically no. Having them in your possession while in Minnesota violates the law. Your safest option is to ship them separately or dispose of them before entering the state.

Are training tools that look like brass knuckles but are made of foam legal?

This depends on whether they function as weapons. Soft foam training items that can’t actually hurt someone might be okay. But it’s a gray area. Law enforcement might still question them.

What happens if I get caught with brass knuckles at the airport?

You’ll face criminal charges under Minnesota law. TSA will confiscate them. And you might miss your flight while dealing with police. Never bring brass knuckles to an airport.

Can I beat a brass knuckles charge if I didn’t know they were illegal?

Probably not. Ignorance of the law is not a defense. You’re responsible for knowing what’s legal. But a lawyer might find other ways to defend your case.

Do plastic or wooden knuckles count as illegal in Minnesota?

Yes. While the statute says “metal knuckles,” courts interpret this broadly. Any knuckle weapon can be charged as a dangerous weapon.

What if the brass knuckles were planted in my car by someone else?

You could argue you didn’t know they were there. But prosecutors will try to prove you knew about them. This is one reason to get a lawyer immediately.

Final Thoughts

Minnesota doesn’t play games with brass knuckles. The law is clear. The penalties are real. And the consequences last for years.

If you don’t own brass knuckles, don’t start now. If you already have them, get rid of them properly. And if you’re facing charges, get a lawyer fast.

The state offers plenty of legal self-defense options. Choose those instead. Pepper spray works. Proper training in self-defense works. Situational awareness works.

Brass knuckles? They just get you in trouble in Minnesota.
