What Exactly Are Brass Knuckles?
Brass knuckles, often called knuckle dusters, are weapons that fit around the knuckles and are meant to be held in the palm. They used to be constructed of metal, like brass, but now you may find them in plastic, polymer, or even wood.
Their main job is to focus the force of a punch, which can hurt the person who gets it quite badly. Many legislatures have banned or limited them because they are mostly used for offensive reasons and have little to no use for peaceful ones.
Why Are Brass Knuckles Illegal in Most Places?
The main reason why brass knuckles illegal in so many places is because of how they were made. Brass knuckles are not like pocket knives because they are made to be used as weapons in hand-to-hand fighting. Because they can be hidden and cause a lot of damage, they are a big public safety issue for law enforcement.
Lawmakers say that having them around makes it more likely that a fight will turn lethal, which is why they are banned in many jurisdictions to avoid deadly situations.
Can You Carry Brass Knuckles in Florida?
If you live in or visit Florida, it's important to know the answer to the question, "Can you carry brass knuckles in Florida?" Florida Statute Section 790.06 makes it plain that it is against the law to carry any slingshot or billie. Courts have also said that brass knuckles are included in this group of weapons that are not allowed.

The rules in the Garden State are just as strict, if not more so. So, are brass knuckles allowed in New Jersey? The New Jersey Code of Criminal Justice says that gravity knives, switchblade knives, daggers, dirks, stilettos, or other dangerous knives, billies, blackjacks, bludgeons, metal knuckles, sandclubs, slingshots, cesti, or similar leather bands studded with metal filings are all illegal to own.
This means that having them, even in your own house, is against the law. There is a clear and solid negative answer to the question of whether or not brass knuckles are lawful in New Jersey. Possession of them is a fourth-degree criminal.
A Look at Other State Laws
Many other states, in addition to Florida and New Jersey, have tight bans. For instance, California, Illinois, New York, and Michigan all say that brass knuckles illegal are unlawful weapons. But in the last few years, certain states, like Arizona and Texas, have made their regulations less strict, which means that people can own guns and occasionally carry them openly.
Before you even think about buying or owning something, you need to look into the laws in your state and even your city or county. The restrictions can be very particular to your area.
What Happened to Brass Knuckles Cartridges?

This is very different from regulated brands like FightSense that focus on legal self-defense weapons.
A Legal Alternative for Self-Defense
FightSense and other firms that sell self-defense gadgets that follow state regulations are not like the illegal weapons we talked about before. FightSense sells things like shock guns and personal alarms, but it's important to remember that they don't sell brass knuckles, which are against the law in most places.

Why Brass Knuckles Are Banned
Brass knuckles aren't just forbidden for no reason; lawmakers have particular reasons for calling them brass knuckles illegal weapons. The main purpose of them is to make a blow stronger by focusing it on small, hard spots that can break bones and hurt tissue badly. Brass knuckles are not useful for anything other than hurting someone.
A knife can be a tool, and a gun can be used for sport. A big reason for this is that it doesn't have a peaceful objective. Law enforcement sees them as easy-to-hide force multipliers that quickly make violence worse, which is a big risk to public safety. This basic trait is what makes brass knuckles unlawful in so many places in the US.

The trend is certainly toward prohibition, but a few states, like Arizona and Texas, have lately made their rules less severe, mostly allowing people to own guns instead of carrying them freely. It is risky to assume that just because you can buy something online, it is legal to have it where you reside. Always check your local laws.

The History and Design of a Prohibited Weapon
Brass knuckles have been around for a long time, going back to ancient times. The concept is basic yet works: a metal frame spreads the force of a punch over the user's knuckles while focusing the impact on small, hard points against the target. This design protects the puncher's hand while doing the most damage to the victim. That's why modern legal systems typically say they are too dangerous for civilians to carry and classify them as illegal.
Traveling with Self-Defense Tools: What You Need to Know
