Karambits are legal to carry in California, but only if you carry the right type the right way in the right place. The state doesn’t ban karambits by name. It classifies knives by their mechanical features, and a karambit’s curved fixed blade or locking folder design almost always lands it in the “dirk or dagger” category, which triggers strict concealed-carry rules and location bans. Getting the classification wrong can turn a traffic stop into a felony.
Fixed-Blade Karambits
A fixed-blade karambit is always a dirk or dagger under California law because the blade is permanently exposed and ready for use as a stabbing weapon. Penal Code 16470 defines a dirk or dagger as any knife capable of ready use as a stabbing weapon that could inflict great bodily injury or death.1California Legislative Information. California Penal Code 16470 Blade shape, length, and finger ring don’t matter. If it can stab and cause serious harm, it qualifies.
Penal Code 21310 makes it illegal to carry a concealed dirk or dagger on your person.2Justia. CALCRIM No. 2501 – Carrying Concealed Explosive or Dirk or Dagger Concealed doesn’t just mean tucked in a waistband. A fixed-blade karambit in a pocket, bag, purse, or under a jacket all count.
Open carry is the legal path. Penal Code 20200 says a knife carried in a sheath worn openly and suspended from the waist is not concealed.3California Legislative Information. California Code PEN 20200 The handle needs to be visible; a long shirt covering it defeats the exemption. Clipped inside a pocket or tucked into a belt without a visible waist-hung sheath is concealed in the eyes of the law.
Penalties
Concealed carry of a dirk or dagger is a wobbler. Prosecutors can charge it as a misdemeanor or a felony depending on circumstances and criminal history. The statute authorizes county jail up to one year for a misdemeanor, or a state prison term under Penal Code 1170(h) for a felony.2Justia. CALCRIM No. 2501 – Carrying Concealed Explosive or Dirk or Dagger A felony conviction can mean 16 months, two years, or three years in county jail. Fines reach $1,000 for a misdemeanor and $10,000 for a felony.
Folding Karambits
Folding karambits depend entirely on blade position. Penal Code 16470 says a folding knife only becomes a dirk or dagger when the blade is “exposed and locked into position.”1California Legislative Information. California Penal Code 16470 A folding karambit carried with the blade closed, in your pocket or a bag, is not a dirk or dagger and is legal to carry concealed. No blade-length limit applies under state law while the blade stays folded.
Open and locked, the picture flips. A locking folder with the blade deployed is treated exactly like a fixed blade: it’s a dirk or dagger, and carrying it concealed is a crime. This is where people get caught. You might carry a folding karambit legally all morning, open it to cut something at lunch, and slide it back in your pocket with the blade still locked. That’s a wobbler offense.
Switchblade Karambits
If a karambit deploys automatically by spring, button, or gravity and the blade is two inches or longer, it’s a switchblade under Penal Code 17235.4California Legislative Information. California Code PEN 17235 Penal Code 21510 makes it a misdemeanor to carry a switchblade on your person, keep one in the driver or passenger area of a vehicle in a public place, or sell or give one to anyone.5California Legislative Information. California Code PEN 21510
A karambit that opens with thumb pressure on the blade or a thumb stud, and has a detent that resists opening, is not a switchblade even if you can flick it out one-handed. The switchblade definition specifically excludes knives that require manual thumb pressure and have a resistance mechanism.4California Legislative Information. California Code PEN 17235 Check the actual mechanism before assuming any assisted-opening karambit is legal.
Places Where Karambits Are Banned
Even a karambit that’s legal on the street is off-limits in several locations.
K-12 Schools
Penal Code 626.10 prohibits bringing a dirk, dagger, knife with a blade longer than two and a half inches, or any folding knife with a locking blade onto the grounds of any public or private school from kindergarten through twelfth grade.6California Legislative Information. California Penal Code 626.10 Almost every karambit hits at least one of those criteria. Violations can carry up to a year in county jail or a state prison term.
Colleges and Universities
The same statute covers the University of California, California State University, California Community Colleges, and private universities. The banned list is narrower: dirks, daggers, ice picks, and fixed-blade knives with blades over two and a half inches.6California Legislative Information. California Penal Code 626.10 Locking folders aren’t listed for colleges the way they are for K-12, but a locking folder with the blade deployed still qualifies as a dirk or dagger under Penal Code 16470.
Government Buildings
Penal Code 171b bans bringing any knife with a blade longer than four inches, fixed or capable of being locked open, into a state or local public building or any government meeting required to be open to the public.7California Legislative Information. California Penal Code 171b The statute also bans switchblades. Karambits under four inches can technically clear this bar, but courthouses and individual buildings often screen more strictly at the door.
Federal Buildings
Federal law goes further. Under 18 U.S.C. 930, possessing a “dangerous weapon” in a federal facility is punishable by up to one year in prison. The statute carves out one exception: a pocket knife with a blade shorter than two and a half inches. Any karambit above that threshold is a dangerous weapon in a federal building. Federal court facilities carry up to two years.8Office of the Law Revision Counsel. 18 USC 930 – Possession of Firearms and Dangerous Weapons in Federal Facilities
Airports
The TSA prohibits all knives in carry-on bags except rounded, blunt-edged items like butter knives and plastic cutlery. There is no minimum blade length that makes a knife acceptable for the cabin. A one-inch folding karambit gets the same treatment as a six-inch fixed blade.9Transportation Security Administration. Knives Checked luggage is fine if the knife is sheathed or securely wrapped.
City Ordinances Can Be Stricter
California cities are free to add restrictions. Los Angeles Municipal Code Section 55.10 makes it illegal to openly carry any knife or dagger with a blade three inches or longer on a public street, sidewalk, park, or any place open to the public. Exceptions exist for lawful occupation, recreation, or recognized religious practice, but casual everyday open carry of a three-inch karambit is off the table.10American Legal Publishing. Los Angeles Municipal Code SEC. 55.10 – Carry Knives or Daggers in Plain View Prohibited
Combine that with state law and Los Angeles creates a trap. State law forbids concealing a fixed-blade karambit. LA city law forbids openly carrying one with a blade three inches or longer. For a fixed-blade karambit at that size, there’s effectively no legal way to carry it in public in LA without a specific exemption. Glendale and other cities have similar three-inch open-carry bans. Check local ordinances before carrying in any California city.
Vehicles
The big vehicle rule is the switchblade rule. Penal Code 21510 bans possessing a switchblade in the driver or passenger area of a vehicle in any public place.5California Legislative Information. California Code PEN 21510 A non-switchblade karambit in a vehicle isn’t inherently illegal, but a fixed-blade karambit within reach and out of sight could be treated as a concealed dirk or dagger. Keep any fixed-blade karambit sheathed and stored in the trunk, or otherwise visible and not hidden.
Owning and Buying
Owning a karambit is legal. No state law bans the knife by name, and there’s no statewide blade-length limit for knives kept at home. Restrictions kick in when you carry the knife in public or bring it to a prohibited location. Certain designs are illegal to own outright under Penal Code 16590, including ballistic knives and knives disguised as everyday objects like cane swords or belt-buckle knives. A karambit sold as a karambit doesn’t fall into those categories. An automatic-deployment karambit with a blade two inches or longer is a switchblade, and Penal Code 21510 restricts its possession, carry, sale, and transfer.5California Legislative Information. California Code PEN 21510
Quick Reference by Knife Type
- Fixed-blade karambit: legal openly in a sheath visibly suspended from the waist under state law; concealed carry is a crime; cities like Los Angeles ban open carry of three-inch-plus blades without a lawful-purpose exception.
- Folding karambit, blade closed: legal openly or concealed, no blade-length limit under state law.
- Folding karambit, blade locked open: treated as a dirk or dagger; concealed carry is illegal; open carry requires a waist-hung sheath; local ordinances may still ban it.
- Switchblade karambit with a blade two inches or longer: illegal to carry on your person, keep in a vehicle’s passenger or driver area, or sell or give away.
Schools, government buildings, federal facilities, and airports are off-limits for virtually any karambit. When in doubt about a location or a specific city’s rules, leave the knife at home or locked in the trunk before you arrive.
