Neck knives are legal to own in California, but carrying one around your neck is a legal gray zone that can land you with a concealed weapon charge. The state’s only clear safe harbor for openly carrying a fixed-blade knife requires the sheath to hang from your waist. A blade on a cord under or over your shirt doesn’t meet that standard, and prosecutors can treat it as a concealed dirk or dagger — a wobbler offense that reaches up to three years in state prison when charged as a felony.
Why Neck Carry Falls Outside the Open-Carry Rule
California Penal Code 20200 protects fixed-blade knives from being treated as concealed weapons, but only when the knife is carried in a sheath “worn openly suspended from the waist of the wearer.”1California Legislative Information. California Penal Code 20200 The statute names the waist and nothing else. Shoulders, chests, and cords around the neck aren’t mentioned, so a neck knife doesn’t get the protection the statute offers to a hip-carried blade.
That matters because the burden shifts. Without PC 20200, you’re asking a judge or jury to accept that your particular carry method wasn’t really concealment. Officers in the field often don’t draw fine distinctions. If the knife isn’t on your hip, they may treat it as hidden, and the question of concealment gets argued later in court rather than resolved on the street.
The Concealed Dirk or Dagger Charge
Hidden under a shirt or jacket, a neck knife is squarely in the territory of Penal Code 21310, which 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 A fixed-blade neck knife fits that description without much argument.
Why you were carrying it doesn’t matter. The standard jury instruction for this charge 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 Utility, self-defense, or everyday-carry reasoning won’t defeat the charge. Knowingly concealing a fixed-blade knife on your body is enough.
Folding Neck Knives Are Treated Differently
PC 16470 adds a specific carve-out for folders. 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 closed folding knife worn around your neck, even under a shirt, is not a concealed dirk or dagger. Open and lock the blade while it’s still hidden on your person, and it becomes one.
That makes folding neck knives considerably safer legally than fixed-blade ones. Keep it folded until you actually need it and you sidestep the PC 21310 problem.
Penalties If You’re Charged
Carrying a concealed dirk or dagger under PC 21310 is a wobbler, meaning prosecutors can file it as either a misdemeanor or a felony depending on the circumstances and your prior record.
- As a misdemeanor: up to one year in county jail and a fine of up to $1,000.4California 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 $10,000.5California Legislative Information. California Penal Code 18
A felony conviction also strips the right to own firearms and leaves a permanent record. The consequences are heavy for what is often just a small utility blade carried the wrong way.
Some Knives Are Banned No Matter How You Carry Them
Open carry on the waist won’t help if the knife itself is on California’s prohibited list. Penal Code 16590 covers “generally prohibited weapons,” which cannot be possessed, manufactured, imported, or sold.6California Legislative Information. California Penal Code 16590 One category to watch with neck knives is disguised blades: knives hidden inside everyday objects like belt buckles, pens, or lipstick cases. A neck knife designed to look like a pendant or medallion could be classified as a disguised weapon. Switchblades with blades two inches or longer are also prohibited.7California Legislative Information. California Penal Code 21510
Place and Local Rules Can Override State Law
A knife carried legally on your waist can still become illegal the moment you walk into certain buildings. Schools, courthouses, city halls, and airport sterile areas all have their own blade restrictions under statutes like PC 626.10 and PC 171b.8California Legislative Information. California Penal Code 626.109California Legislative Information. California Penal Code 171b
Cities can also go further than the state. Santa Monica, for example, bans carrying any knife, dagger, or sword in plain view in public areas, which is the opposite of the state’s open-carry framework.10City of Santa Monica. Santa Monica Code Chapter 3.29 – Carrying or Wearing of Knives, Daggers, and Swords in Plain View in Public Areas Prohibited Before carrying any knife openly, check whether the city or county has added its own rules on top of state law.
How to Carry a Neck Knife Legally in California
If you want to use a neck knife and stay clear of PC 21310, your options are narrow but workable.
- Move it to your waist. Taking the knife off the cord and putting it in a sheath that hangs openly from your belt or waistband is the only carry method with explicit statutory protection under PC 20200.1California Legislative Information. California Penal Code 20200
- Choose a folding model and keep it folded. A closed folding knife worn around your neck isn’t a dirk or dagger under PC 16470, so it stays outside the concealed-weapon statute as long as the blade isn’t locked open.3California Legislative Information. California Penal Code 16470
- Avoid any neck knife that looks like something else. Disguised blades fall under the prohibited weapons statute regardless of how they’re carried.6California Legislative Information. California Penal Code 16590
- Check the local ordinances where you’ll actually be carrying.
Wearing a fixed-blade neck knife on a cord, visible or hidden, is one of the riskier ways to carry a blade in California. The open-carry safe harbor wasn’t written with neck carry in mind, and that gap is what exposes you to a wobbler charge that can follow you for years.
