Brass Knuckle Laws in Massachusetts (2026): Don’t Get Caught Off Guard
Most people assume brass knuckles are just edgy collectibles. They’re wrong. In Massachusetts, carrying them is a serious crime with real jail time attached. Let’s break down exactly what the law says and what it means for you.
What Are Brass Knuckles?
Brass knuckles are handheld weapons designed to fit over your fingers. They make a punch hit harder by putting metal between your knuckles and whatever you’re hitting. That’s the whole point — and that’s exactly why Massachusetts bans them.
The law defines them broadly. It doesn’t matter if they’re made of brass, steel, aluminum, or another hard material. Even plastic versions can fall under the same ban. Honestly, if it fits over your knuckles and could hurt someone, Massachusetts law likely covers it.
Knuckle-knives are included too. That’s a brass knuckle with a blade attached. Same deal — totally prohibited.
Is It Illegal to Own Brass Knuckles in Massachusetts?
Okay, this part trips people up. So let me break it down carefully.
The main law is Massachusetts General Laws, Chapter 269, Section 10(b). It specifically bans carrying brass knuckles on your person or in your vehicle. The statute does not directly ban keeping them inside your home or place of business.
Sound like a loophole? Kind of. But stay with me here.
Here’s the problem. If police find brass knuckles during a home search, prosecutors often still file charges under Chapter 269, Section 10. You might win in court — but you’ll spend money on a lawyer to get there. That’s a headache most people don’t want.
The bottom line? Massachusetts treats brass knuckles as dangerous weapons. Even at home, the legal risk is real.
Carrying Brass Knuckles: Clearly Illegal
Carrying brass knuckles anywhere outside your home is against the law. This means on your body, in your bag, or in your car. It doesn’t matter if they’re hidden or out in the open. It doesn’t matter if you never planned to use them. Carrying them is the crime.
Wondering if your intent matters? It doesn’t. You don’t have to threaten anyone or commit another crime. Just having them on you is enough for charges.
Buying, Selling, and Manufacturing: Also Illegal
This one surprises a lot of people. You can’t legally buy brass knuckles in Massachusetts. You can’t sell them either. Manufacturing them is also prohibited under state law.
What about buying online? Still illegal. The law applies regardless of where the seller is located. If you order them and they ship to your Massachusetts address, you’ve potentially broken the law.
Wait, it gets more complicated. Even items that look like brass knuckles can be illegal. Certain novelty jewelry or keychains shaped like knuckles have been the subject of charges. The design matters more than the label.
Penalties for Violating the Law
Let’s talk about what happens if you get caught. The consequences are serious.
For a first-time offense with no prior felony record, you could face up to 2.5 years in jail or a house of correction. You could also face a fine of up to $1,000. The court decides the exact punishment based on the details of your case.
Here’s where it gets more serious. If you have a prior felony conviction, the penalties jump significantly. You’re looking at 2.5 to 5 years in state prison. The judge also has less flexibility with sentencing.
Think of it like this: a first offense is bad. A second offense for someone with a felony record is much, much worse.
If you use brass knuckles during an assault or another crime, the charges stack up fast. Simple assault becomes assault with a dangerous weapon. That’s a felony charge on its own — separate from the weapons charge. You could be facing multiple serious counts at once.
Getting Arrested While Carrying
There’s a separate and harsher offense in the law. Getting caught carrying a dangerous weapon at the time of an arrest makes things worse. Prosecutors treat this more seriously than regular carrying charges.
This matters a lot. Say police arrest you for something unrelated. They search you and find brass knuckles. Now you have the original charge plus the weapons charge. Both will be prosecuted.
Okay, pause. Read this next part carefully.
There is no “I didn’t know” defense here. Claiming you forgot they were in your bag won’t help. The law requires that you “carry” the item, but courts have interpreted this broadly. Prosecutors don’t need to prove you planned to use them.
What About Antiques or Collectibles?
Many people assume antique weapons are exempt. They are not. Massachusetts does not carve out an exception for antique or collectible brass knuckles. Age doesn’t matter. Rarity doesn’t matter. If it’s brass knuckles, it’s prohibited.
This surprises collectors and history buffs. A set of WWI-era knuckles is just as illegal to carry as a brand-new pair. Honestly, this is the part most people miss.
Fake or Decorative Brass Knuckles
This is a tricky area. Massachusetts law covers “knuckles of any substance which could be put to the same use with the same or similar effect as metallic knuckles.” That’s a wide net.
A friend told me about buying novelty brass knuckle belt buckles online. They seemed like fashion accessories. But depending on the material and design, they might still fall under the law. The state looks at whether it could function as a weapon.
If you’re unsure whether an item counts, assume it does. That’s the safest approach in Massachusetts.
Are There Any Exceptions?
Most states have exceptions for law enforcement or military. Massachusetts is no different there. Officers acting in their official capacity are generally exempt from these restrictions.
There is also a narrow exception tied to firearms licenses. People with an active license to carry firearms (LTC) may have some additional legal ground to stand on. But this is complex and doesn’t give blanket permission to carry brass knuckles. You’d need a lawyer to sort out whether your specific situation qualifies.
For the average person? There are no useful exceptions. The ban is essentially total for regular civilians.
What to Do If You Already Own Them
Maybe you bought brass knuckles in another state where they’re legal. Maybe you inherited them. Maybe you didn’t know the rules. You’re not alone — this confuses a lot of people.
Here’s what you should do. Don’t carry them or transport them in Massachusetts. Consult a Massachusetts criminal defense attorney for personalized advice. They can tell you the safest path forward based on your situation.
Do not try to sell them locally. That creates another potential charge. And do not bring them across state lines thinking you’re in the clear — transporting prohibited weapons into Massachusetts can still lead to charges.
Brass Knuckles in Schools and Government Buildings
This is a hard line in Massachusetts law. Carrying any dangerous weapon — including brass knuckles — in or around schools is a separate crime entirely. It doesn’t matter if you have an LTC or another license.
The law covers elementary schools, high schools, colleges, and universities. It also covers school grounds, not just the buildings themselves. Violating this rule carries its own penalties on top of any other charges.
Government buildings and courthouses have even stricter rules. Bottom line: never bring brass knuckles anywhere near these locations.
How This Compares to Other States
Massachusetts is one of the stricter states on this issue. States like Texas, Arizona, and Georgia allow people to own and carry brass knuckles pretty freely. That’s a big contrast.
Some states only ban concealed carry of brass knuckles. Others only ban using them in crimes. Massachusetts bans carrying them period, with very few exceptions.
If you travel between states, this matters. Something legal in your home state may be a crime the moment you cross into Massachusetts. Don’t assume what works in one place works everywhere.
Frequently Asked Questions
Can I keep brass knuckles at home in Massachusetts? The law primarily bans carrying them, not keeping them at home. However, police have charged people found with them during home searches, so the legal risk exists even at home.
What if I bought brass knuckles in another state? Bringing them into Massachusetts is still potentially illegal. State law applies to possession within the state, regardless of where they were purchased.
Are plastic or rubber knuckles also illegal? Yes. The law covers any substance that could be used in the same way as metal knuckles. Plastic or hard rubber versions can still lead to charges.
Does having a firearms license let me carry brass knuckles? Not straightforwardly. The LTC license creates a narrow legal argument, but it’s not a clear exemption. Talk to an attorney before relying on this.
What should I do if I’m charged with carrying brass knuckles? Contact a Massachusetts criminal defense attorney immediately. Do not explain yourself to police without a lawyer present. The charges can escalate quickly.
Final Thoughts
Massachusetts takes brass knuckle laws seriously. Carrying them can land you in jail, even for a first offense. Buying or selling them adds more legal risk. And if you have a prior felony record, the stakes are much higher.
Now you know the rules. Stay informed, stay safe, and when in doubt, call a lawyer before doing anything that could get you in trouble. It’s always better to ask first.
