Neck knives are legal to own in California, but wearing one is legally risky. The state’s only clear protection for openly carrying a fixed-blade knife requires the sheath to hang from your waist, and a knife on a cord around your neck does not fit that description. That gap is why the question “are neck knives legal in California” doesn’t have a clean yes-or-no answer: the knife is fine, the carry method is the problem.
Why the Waist Rule Matters
California Penal Code 20200 says a knife carried in a sheath “worn openly suspended from the waist of the wearer” is not considered concealed.1California Legislative Information. California Penal Code 20200 The wording is narrow on purpose. Shoulders, chests, and neck cords are not mentioned. If the knife isn’t hanging from your waist in a visible sheath, PC 20200’s protection doesn’t apply to you.
A neck knife worn over a shirt is arguably visible, but “arguably” is not a defense you want to rely on. Without the statutory safe harbor, you’d be asking a judge or jury to accept that your carry method wasn’t concealment. Officers in the field often don’t draw fine distinctions. If the knife isn’t on your hip, they may treat it as concealed and let the courts sort it out later.
The Concealed Dirk or Dagger Charge
Tucked under a shirt or jacket, a neck knife is unambiguously hidden, and California Penal Code 21310 makes it a crime to carry a concealed dirk or dagger on your person.2Justia. California Criminal Jury Instructions – CALCRIM No. 2501 Carrying Concealed Explosive or Dirk or Dagger Penal Code 16470 defines a dirk or dagger as any knife or instrument capable of ready use as a stabbing weapon that could inflict great bodily injury or death.3California Legislative Information. California Penal Code 16470 Essentially every fixed-blade neck knife qualifies.
Your reason for carrying doesn’t matter. The standard jury instruction says the prosecution does not have to prove the defendant used or intended to use the item as a weapon.2Justia. California Criminal Jury Instructions – CALCRIM No. 2501 Carrying Concealed Explosive or Dirk or Dagger Knowingly concealing a fixed-blade knife on your body is enough for the charge.
Folding Neck Knives Are Treated Differently
PC 16470’s second sentence carves out folding knives: a nonlocking folding knife or pocketknife qualifies as a dirk or dagger “only if the blade of the knife is exposed and locked into position.”3California Legislative Information. California Penal Code 16470 A folding neck knife carried closed, whether visible or under a shirt, is not a concealed dirk or dagger. Open and lock the blade while it’s still hidden on you, and it becomes one.
Some Knives Are Banned Regardless of Carry Method
Penal Code 16590 lists generally prohibited weapons that you cannot possess, manufacture, import, or sell in California at all.4California Legislative Information. California Penal Code 16590 If your neck knife falls into one of these categories, waist carry won’t save you:
- Ballistic knives, which propel the blade by spring or other mechanism
- Switchblades with blades two inches or longer that open automatically by button, pressure, or a flick of the wrist5California Legislative Information. California Penal Code 21510
- Cane swords
- Disguised knives concealed inside everyday objects like air gauges, belt buckles, lipstick cases, or writing pens
Novelty neck knives designed to look like pendants or medallions can fall under the disguised-weapon category. The classification is broad enough to catch designs that hide a blade’s true nature.
Places You Can’t Bring a Neck Knife
Even a legally carried knife becomes illegal in certain locations. Penal Code 626.10 prohibits bringing any dirk, dagger, or knife with a blade longer than two and a half inches onto K-12 school grounds, and fixed-blade knives with blades over two and a half inches are similarly banned on college and university campuses.6California Legislative Information. California Penal Code 626.10 Penal Code 171b bans any knife with a fixed blade, or a lockable blade, longer than four inches inside state or local public buildings such as courthouses, city halls, and open public meetings.7California Legislative Information. California Penal Code 171b Airport sterile areas and passenger vessel terminals have their own knife prohibitions.8American Knife and Tool Institute. California Knife Laws
City Rules Can Reverse the State Framework
Local ordinances can be stricter than state law, and some flip the open-carry rule on its head. Santa Monica bans carrying any knife, dagger, or sword in plain view in public areas, with limited exceptions for lawful occupations, restaurant use, recreation, and religious practice.9City of Santa Monica. Santa Monica Code Chapter 3.29 – Carrying or Wearing of Knives, Daggers, and Swords in Plain View in Public Areas Prohibited Violations carry fines up to $500 and potential jail time up to six months. Other California cities have their own restrictions. Check the ordinance where you’ll actually be walking around.
What a Conviction Costs
A concealed dirk or dagger charge under PC 21310 is a wobbler. Prosecutors can file it as a misdemeanor or a felony, and the choice usually turns on the circumstances of the arrest and any prior record.
- As a misdemeanor: up to one year in county jail and a fine of up to $1,00010California Legislative Information. California Penal Code 19
- As a felony: 16 months, two years, or three years in state prison and a fine of up to $10,00011California Legislative Information. California Penal Code 18
A felony conviction also means losing firearm rights and living with a permanent criminal record. That’s a heavy price for the wrong carry method on an otherwise legal knife.
How to Carry a Neck Knife Legally
If you want to carry one in California, your options are narrow but workable:
- Move a fixed-blade knife off the neck cord and into a sheath that hangs openly from your belt or waistband. That is the only carry method with explicit statutory protection under PC 20200.1California Legislative Information. California Penal Code 20200
- Choose a folding neck knife and keep it closed. A closed folding knife is not a dirk or dagger under PC 16470, so it can be carried openly or concealed.3California Legislative Information. California Penal Code 16470
- Confirm the local ordinance in the city or county where you’ll be carrying, because state legality does not override a municipal ban on visible knives.
Wearing a fixed-blade neck knife on a cord, visible or not, is one of the riskiest ways to carry a blade in California. The open-carry safe harbor was not written with neck carry in mind, and that omission leaves you exposed to a wobbler charge that can follow you for years.
