Steel throwing stars, or shuriken, face strict legal regulations in the U.S., and I’ll be direct: you need to check your local laws before considering ownership. Many states like California and New York completely ban their possession, while others require specific permits or limit them to martial arts training facilities. You could face serious penalties, including misdemeanor or felony charges, for illegal possession. If you’re traveling, remember that TSA prohibits them in carry-on luggage, and crossing state lines creates additional legal complications. There’s much more to understand about the complex legal landscape surrounding these weapons.

Historical Background of Throwing Stars
Dating back to feudal Japan, throwing stars (shuriken) originated as concealed weapons among ninjas and samurai warriors. I find it fascinating that these weapons weren’t initially star-shaped but came in various forms, including straight needles and flat, pointed plates.
The term “shuriken” literally translates to “sword hidden in the hand,” reflecting their covert nature. Curiously, like many modern throwing knives, traditional throwing stars were made from robust materials such as 440 stainless steel.
During the Sengoku period (1467-1615), I’ve learned that warriors primarily used throwing stars as supplementary weapons, not as their main combat tools. They’d often coat the points with poison to make them more lethal, though they mainly served to distract or delay opponents rather than deliver fatal blows.
Traditional throwing stars were crafted from everyday items like needles, nails, and spikes. You might be surprised to know that many were repurposed from farming tools or carpentry equipment.
As martial arts evolved, the more recognizable star shape (shaken) emerged, featuring multiple points and a center hole for better grip and flight characteristics. Today’s modern steel throwing stars closely resemble these later designs, though they’re primarily used in martial arts demonstrations and collections rather than combat.
State Laws and Restrictions
The legal landscape surrounding steel throwing stars varies dramatically across the United States.
I’ve researched state laws extensively and can tell you that several states, including California, New York, and Massachusetts, have completely banned the possession and sale of throwing stars. Other states maintain strict regulations about who can own them and under what circumstances.
Similarly, while telescopic steel batons are now permissible in California, it’s essential to understand the specific laws regarding other self-defense tools like throwing stars.
I want to emphasize that in states where throwing stars are legal, you’ll still need to comply with specific restrictions. For instance, Indiana allows ownership but prohibits carrying them concealed, while Arizona permits possession only on private property.
Some states classify throwing stars as “dangerous weapons” or “martial arts weapons,” requiring special permits or licenses.
If you’re considering purchasing throwing stars, I strongly recommend checking your local and state laws first.
You’ll need to look up both possession and transportation regulations, as they often differ. In many cases, even if ownership is legal at home, carrying throwing stars in public places or across state lines could result in serious legal consequences, including misdemeanor or felony charges depending on your jurisdiction.
Federal Weapon Classification Guidelines

Federal guidelines regarding throwing stars stem from their classification as martial arts weapons under U.S. law. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) doesn’t specifically regulate throwing stars at the federal level, but they’re subject to customs restrictions when imported from other countries.
These stars, made of materials like stainless steel or chrome, have specific design features such as multiple points for precision and power. I need to point out that throwing stars fall under the broader category of “dangerous weapons” in federal statutes, particularly when carried across state lines or into federal buildings.
You’ll find they’re specifically mentioned in 15 U.S.C. § 1245, which prohibits their possession in certain federal facilities and during interstate transport unless properly declared and packaged.
Under federal guidelines, I can tell you that throwing stars aren’t classified as firearms or destructive devices, but they’re considered “dangerous weapons” when used with intent to cause harm.
This classification affects how they’re treated in federal prosecutions and sentencing guidelines. You should know that federal law enforcement can charge you with weapons violations if you’re caught carrying throwing stars in restricted areas like airports, federal buildings, or across state lines without proper documentation.
Martial Arts Training Exceptions
While many jurisdictions restrict throwing star ownership, legitimate martial arts schools often qualify for training exceptions under state laws.
These exceptions can be compared to exceptions made for the possession and use of certain throwing knives designed for practice. I’ve found that certified dojos and training facilities can apply for special permits allowing them to possess and use throwing stars (shuriken) for educational purposes.
These exemptions typically require strict documentation of the school’s credentials and teaching methodology.
I should point out that to qualify for these exceptions, schools must demonstrate proper safety protocols, secure storage procedures, and professional instructor certification.
Most states require that throwing star training occurs only under direct supervision of qualified instructors within designated training areas. Students aren’t permitted to take the weapons home or practice independently.
In my research of various state regulations, I’ve noticed that schools must maintain detailed records of their throwing star inventory and student participation.
Some jurisdictions mandate regular inspections and renewal of training permits. Additionally, many schools must carry specific insurance coverage for weapons training and require students to sign thorough liability waivers.
These measures guarantee that traditional martial arts training can continue while maintaining public safety standards.
Penalties for Illegal Possession

Across most states, unlawful possession of throwing stars can result in serious criminal charges and penalties. I’ve found that most jurisdictions classify these weapons as prohibited or restricted, typically treating violations as misdemeanors.
You could face fines ranging from $500 to $5,000 and potential jail time of up to one year. In states with stricter weapons laws like California and New York, you might face felony charges if you’re caught carrying throwing stars, especially if you have prior weapons convictions.
Additionally, if you’re found in possession of other dangerous items, such as a Rechargeable Tactical BashLite Stun Gun Flashlight, penalties could be compounded. I should mention that penalties become more severe if you’re caught using throwing stars in the commission of another crime, which could result in additional charges and extended prison sentences of 2-5 years.
If you’re under 18, you’ll likely face juvenile court proceedings, though the penalties are generally less severe.
Keep in mind that some jurisdictions also mandate weapon confiscation and may require completion of community service or weapons safety courses. In certain cases, a conviction could affect your ability to own other weapons in the future or impact employment opportunities that require background checks.
Transportation and Travel Regulations
According to TSA regulations, you can’t transport throwing stars in carry-on luggage under any circumstances.
If you need to transport them by air, you must pack them securely in your checked baggage and declare them at check-in. I recommend placing them in a locked, hard-sided container to prevent any shifting during transit.
When driving across state lines, you’ll need to research the laws for each state you’re traveling through.
I’ve found that some states consider throwing stars illegal weapons, meaning you can’t transport them through these jurisdictions even if they’re legal in your destination state. If you’re stopped for a traffic violation, having throwing stars in your vehicle could result in weapons charges.
For international travel, I must emphasize that most countries strictly prohibit throwing stars.
Customs officials will confiscate them, and you could face serious legal consequences. Even if you have a legitimate collection or use them for martial arts training, you’ll need to obtain special permits or face import restrictions.
I recommend checking with embassies or customs offices before attempting any international transport.
Collector Rights and Limitations

Legitimate collectors of throwing stars face a complex web of state-by-state restrictions that can limit their ability to build and maintain collections.
If you’re planning to collect throwing stars, you’ll need to understand both your rights and the specific limitations in your area.
I recommend checking if your state requires documentation or permits for your collection. Some states allow possession with proof that you’re a genuine collector, while others may demand registration of each piece.
You’ll also find that certain states restrict the number of throwing stars you can own, regardless of your collector status.
You should know that displaying your collection can be tricky.
I’ve found that many jurisdictions prohibit public exhibition of throwing stars, even for legitimate collectors. You’ll need to store them securely in a private space, and in some cases, you must keep detailed records of acquisitions and sales.
If you’re selling pieces from your collection, you’ll face additional regulations.
I advise verifying buyer credentials and maintaining thorough transaction records, as many states require documentation of all throwing star transfers, even between collectors.
Safety Requirements for Legal Use
Practitioners who legally use throwing stars must adhere to strict safety protocols that vary by jurisdiction.
I’ll tell you the core requirements that most areas enforce: you’ll need a designated practice area with proper backstops, usually made of wood or specialized materials, and located away from any public spaces or passersby.
You’re typically required to maintain a safety perimeter of at least 20 feet around your throwing area and guarantee that no one can accidentally walk into your throwing zone.
I’ve found that most jurisdictions require you to post visible warning signs and have emergency medical supplies on hand.
When it comes to personal safety gear, you’ll need to wear appropriate eye protection, closed-toe shoes, and often protective gloves.
I recommend storing your throwing stars in locked containers when not in use, as many jurisdictions mandate secure storage.
You’ll also need to regularly inspect your throwing stars for damage or wear that could make them unsafe.
If you’re practicing at a martial arts facility, you’ll need to comply with their additional safety protocols and guarantee you have proper supervision from qualified instructors.
Licensing and Permit Requirements

A jurisdiction’s licensing requirements for throwing stars vary dramatically across different regions. In some areas, I’ve found that you’ll need both a weapons permit and specialized martial arts certification to legally possess and use throwing stars.
Other locations completely prohibit their ownership, while some have no specific regulations at all.
If you’re interested in legally obtaining throwing stars, I recommend first checking your local laws and contacting your police department. You’ll often need to submit an application, undergo a background check, and provide proof of proper training.
In states like California, you must obtain a special permit specifically for martial arts weapons, while in New York, throwing stars are completely banned regardless of permits.
For martial arts schools and instructors, I’ve noticed additional licensing requirements often apply. You’ll typically need to demonstrate professional credentials, maintain detailed student records, and secure specific liability insurance.
Some jurisdictions require regular permit renewals and ongoing training certifications. Remember that transporting throwing stars across state lines can involve additional federal restrictions and permits, even if you’re licensed in your home state.
International Laws and Customs
Throughout the world, laws governing throwing stars vary dramatically from country to country.
I’ve found that many nations classify throwing stars as prohibited weapons, particularly in Europe where countries like the UK, Germany, and France have outright bans on their possession and importation.
In Asia, despite being the birthplace of throwing stars, countries maintain strict regulations.
Japan, for instance, requires special permits even for martial arts practitioners, while South Korea prohibits civilian ownership entirely.
I can tell you that China allows limited ownership for traditional martial arts schools but bans private possession.
When you’re traveling internationally, I strongly advise against packing throwing stars in your luggage, as customs officials will likely confiscate them and you could face criminal charges.
In Australia and New Zealand, they’re classified as prohibited imports, and you’ll need special permission from government authorities to bring them in.
Canadian law lists throwing stars as prohibited weapons, though there are exceptions for legitimate martial arts training.
I’ve noticed that Mexico and most South American countries also maintain strict prohibitions on these weapons, with substantial penalties for unauthorized possession or transport.
