Are nunchucks illegal? In almost every U.S. state, no. As of 2025, only one state still enforces an outright ban on possessing them, down from four just a few years ago. That said, “legal to own” and “legal to carry down the street” are two different questions, and broader weapons laws often catch nunchucks even where no statute names them.
States That Still Ban Possession
The list has shrunk fast. As recently as 2018, four states specifically outlawed nunchucks. One ban was struck down by a federal court that year as unconstitutional under the Second Amendment, and two more states repealed their prohibitions through legislation around 2019 on the same constitutional reasoning. That leaves one state with an active ban on the books. If you live there, simply keeping a pair of nunchucks at home can result in criminal charges.
A statute that doesn’t mention nunchucks by name isn’t necessarily a green light. Several states fold them into broader categories like “dangerous weapons,” “deadly weapons,” or “bludgeons.” In those states, legality turns on how prosecutors and courts read the umbrella term, and some states also treat home possession differently from carrying in public.
Carrying Nunchucks in Public
Owning nunchucks legally and carrying them legally are separate questions. Many states allow possession at home but treat concealed carry of any instrument that could be used as a weapon as a criminal offense. Nunchucks fit that description without much argument.
Some states require a permit to carry any concealed weapon, including blunt instruments and martial arts equipment. Others allow open carry but not concealment. A few limit nunchuck use to martial arts studios or training settings, so any public carry is off the table regardless of whether the weapon is visible.
School grounds, government buildings, courthouses, and other sensitive locations almost universally prohibit weapons of any kind. Bringing nunchucks into one of those places usually triggers separate charges on top of any underlying weapons offense, and the penalties are steeper.
Criminal Penalties
Where nunchucks are banned or restricted, penalties run from a modest fine to several years in prison. Severity depends on the jurisdiction, your criminal history, and whether the nunchucks were involved in a violent incident.
- Misdemeanor possession commonly carries fines and up to one year in county jail. First-time offenders with no prior felony convictions sometimes face reduced penalties.
- Felony possession applies in jurisdictions that treat nunchucks as a per se prohibited weapon. State prison time can range from roughly two to five years.
- Wobbler offenses can be charged as either a misdemeanor or felony at the prosecutor’s discretion. Your record, where you were caught, and whether you were doing anything threatening all factor in.
Penalties climb sharply if nunchucks are used during a crime. Using any weapon during an assault or robbery typically triggers a sentencing enhancement, adding years to whatever the base offense would carry.
Why Most Bans Fell: Maloney v. Singas
The case behind the shift is Maloney v. Singas, decided by the U.S. District Court for the Eastern District of New York in December 2018. The plaintiff, a martial arts practitioner and attorney, had challenged New York’s 1974 ban on “chuka sticks” and litigated the case for over fifteen years before winning.1Casemine. Maloney v. Singas
The court found nunchucks are the type of bearable arms protected by the Second Amendment and declared the New York ban unconstitutional and void.1Casemine. Maloney v. Singas
One practical point matters for anyone checking their own state’s code: the New York legislature never formally repealed the statute, so “chuka stick” still appears on the books as a prohibited weapon even though the ban cannot be enforced. Other states may have similar gaps between statute text and current enforceability. Read the statute, then check whether a court decision has changed the picture.
Self-Defense and Civil Liability
Using nunchucks to defend yourself creates legal exposure even where possession is perfectly legal. Self-defense law generally requires proportional force. Nunchucks can cause serious head injuries and broken bones, so pulling them out during a fistfight can be treated as disproportionate. Whether a court agrees that your use was justified turns on the facts: how serious the threat was, whether you could have retreated, and how a reasonable person would have responded.
Beyond criminal charges, anyone you injure with nunchucks can sue you in civil court. A civil battery claim requires only that you made intentional, non-consensual contact that caused harm. The injured person doesn’t have to prove you intended the specific injury, just that you intended the contact. Damages can include medical expenses, lost income, pain and suffering, and in extreme cases, punitive damages.
You can win a self-defense argument in criminal court and still lose a civil lawsuit over the same incident, because the burden of proof is lower on the civil side. Carrying nunchucks for self-defense is a calculated risk even where it’s legal.
Flying, Driving, and Shipping
The TSA prohibits nunchucks in carry-on bags but allows them in checked luggage.2Transportation Security Administration. Complete List (Alphabetical) No special declaration or packaging is required for checked bags under TSA rules. TSA rules only govern the security checkpoint, though. They don’t override state or local weapons laws at your destination.
That destination question is where travelers get into trouble. Flying or driving from a state where nunchucks are legal to one where they’re banned can produce criminal charges on arrival, even if you packed them lawfully at home. Unlike firearms, which have some federal protections for interstate transport under the Firearms Owners’ Protection Act, nunchucks have no equivalent federal safe-passage provision.
Shipping raises separate issues. The U.S. Postal Service prohibits mailing items “dangerous or injurious to life, health, or property.” Nunchucks aren’t explicitly named on the USPS prohibited items list, but they could fall under general restrictions on items designed to cause injury. Private carriers like UPS and FedEx set their own policies and may refuse shipments of martial arts weapons to certain addresses.
How to Check the Law Where You Live
Search your state legislature’s website for “nunchaku,” “chuka stick,” or “martial arts weapon” within the criminal or penal code. Most state legislature sites have searchable statute databases. Look for statutes that name nunchucks specifically and for broader “dangerous weapon” or “deadly weapon” definitions that might sweep them in.
Don’t stop at the state level. Counties and municipalities sometimes impose weapons restrictions that go beyond state law, especially in urban areas. A call to your local police department’s non-emergency line can clarify whether any local ordinances apply. If you plan to train at a martial arts studio, the owner likely already knows the local rules.
Pay attention to the date of any statute you find, and check for court decisions or amendments that may have changed things since. When a weapons charge is on the table, a short consultation with a criminal defense attorney in your jurisdiction is worth the money.
