Swords are not illegal in California. You can own a katana, longsword, saber, rapier, or almost any other traditional blade, keep it at home, mount it on a wall, and train with it, all without a permit, license, or registration. The law gets strict once a sword leaves the house: concealing one on your person is a crime, certain disguised blades are banned outright, and several locations are off-limits no matter how the sword is carried.
How California Classifies Swords
No California statute uses the word “sword.” Instead, a sword falls under the definition of a “dirk” or “dagger” in Penal Code 16470, which covers any knife or instrument capable of ready use as a stabbing weapon that could inflict great bodily injury or death.1California Legislative Information. California Penal Code PEN 16470 A fixed-blade sword clearly qualifies, and that classification is what triggers the carry rules below.
One category of blade is banned outright. Penal Code 16590 lists cane swords among the “generally prohibited weapons,” meaning any cane, walking stick, umbrella, or similar object with a blade hidden inside.2California Legislative Information. California Code Penal Code PEN 16590 Possession alone is a wobbler that can be filed as a misdemeanor or a felony, even if the sword never leaves your home. Standard swords not designed for concealment carry no such restriction.
Open Carry Versus Concealed Carry
The line between legal and illegal in public is visibility. Penal Code 20200 states that a knife carried in a sheath worn openly and suspended from the waist is not concealed.3California Legislative Information. California Penal Code PEN 20200 Since swords qualify as dirks or daggers, the same rule applies. Walking down the street with a sword hanging from your belt in an open sheath does not violate the concealed-carry statute.
Legal and unnoticed are different things. An officer who sees you walking through a neighborhood with a three-foot blade on your hip may still approach you, and if bystanders are alarmed, you could face a disturbing-the-peace charge under Penal Code 415.4California Legislative Information. California Penal Code PEN 415
Concealed carry is where people get charged. Penal Code 21310 makes it a crime to carry a concealed dirk or dagger on your person.5California Legislative Information. California Code Penal Code PEN 21310 A sword hidden in a bag, wrapped in a coat, or otherwise out of plain view while you carry it in public meets that definition. In People v. Rubalcava (2000), the California Supreme Court held that possessing a concealed dirk or dagger is enough for criminal liability without any proof of unlawful intent.6Justia. People v. Rubalcava Forgetting a wrapped blade in a backpack can produce the same charge as deliberately hiding one.
Where You Cannot Bring a Sword
Some locations are off-limits regardless of open carry.
Government Buildings and Public Meetings
Penal Code 171b bars dirks, daggers, and other deadly weapons from any state or local public building or any meeting required to be open to the public.7California Legislative Information. California Code Penal Code PEN 171b Courthouses, city halls, and DMV offices are all covered. Federal facilities are covered separately by 18 U.S.C. § 930, which prohibits dangerous weapons and carries up to one year in prison for general federal buildings and up to two years for federal courthouses.8Office of the Law Revision Counsel. 18 U.S. Code 930 – Possession of Firearms and Dangerous Weapons in Federal Facilities The only bladed exception in the federal statute is a pocket knife with a blade under 2½ inches, which no sword will satisfy.
Schools
Penal Code 626.10 makes it a crime to bring a dirk, dagger, or knife with a blade longer than 2½ inches onto the grounds of any public or private K–12 school.9California Legislative Information. California Penal Code PEN 626.10 There is no built-in exception for historical demonstrations, martial arts props, or theater. Coordinate with the administration in advance if a school event calls for a blade.
Airports and Transit
The TSA prohibits swords in carry-on bags. They are permitted in checked luggage if sheathed or securely wrapped to protect baggage handlers, and the final call rests with the officer at the checkpoint.10Transportation Security Administration. Swords Local transit systems can set their own weapon rules, so check before boarding a bus or train with any blade.
Transporting a Sword
Moving a sword between your home and a dojo, convention, or buyer comes down to not creating a concealed-carry problem. Keep the sword in a locked case in the trunk of your car, or in another secured area that is not readily accessible from the driver’s seat. A sword on the passenger seat or tucked under a coat in the back could still trigger a Penal Code 21310 charge.5California Legislative Information. California Code Penal Code PEN 21310
For shipping, USPS requires that sharp-pointed or sharp-edged instruments be wrapped so their points and edges cannot cut through the outer packaging.11USPS Domestic Mail Manual Archive. DMM 601 Mailability Standards Private carriers like FedEx and UPS do not publish blanket bans on swords, but individual locations may decline the shipment.
Penalties
What you face depends on the specific offense and how the prosecutor files it.
- Carrying a concealed dirk or dagger under Penal Code 21310 is a wobbler. As a misdemeanor it carries up to one year in county jail and a fine of up to $1,000. As a felony the sentence can reach three years in state prison.5California Legislative Information. California Code Penal Code PEN 21310
- Brandishing a deadly weapon other than a firearm under Penal Code 417 is a misdemeanor with a minimum of 30 days in county jail.12California Legislative Information. California Penal Code PEN 417
- Assault with a deadly weapon under Penal Code 245(a)(1) is punishable by two, three, or four years in state prison, or up to one year in county jail, plus a fine of up to $10,000.13California Legislative Information. California Code Penal Code PEN 245
- Possessing a cane sword or other prohibited weapon under Penal Code 16590 is also a wobbler, with a misdemeanor carrying up to one year in county jail and a felony carrying state prison time.2California Legislative Information. California Code Penal Code PEN 16590
Prosecutors weigh prior record, location, and whether anyone was threatened when deciding how to file a wobbler. A collector with an innocent explanation and someone brandishing a blade during another offense both technically fall under the same statute, but they rarely end up with the same outcome.
Notes for Collectors
Most traditional swords can be legally owned without any permit, registration, or paperwork. The traps are concealment features and careless carry.
Stay away from anything with a blade built into another object. Cane swords, umbrella swords, and walking-stick blades all fall under Penal Code 16590 as prohibited weapons, and mere possession supports a charge.2California Legislative Information. California Code Penal Code PEN 16590 Switchblade-style knives with blades of two inches or longer are separately illegal to carry or possess in public under Penal Code 21510.14California Legislative Information. California Code Penal Code PEN 21510
California imposes no state-level licensing requirement on private sales of bladed weapons. Local governments may regulate edged-weapon sales through their own ordinances, including buyer age limits, so check city and county rules before selling at a show or through a storefront.
