Types of Knives Legal in California

Folding Pocket Knives:

Folding pocket knives are legal to own and carry in California. These encompass models like slip joint, lockback, liner lock, frame lock, and button lock, which have a blade that can be folded into the handle, making them easy to store and transport​.

However, if a folding knife is extended and locked into position, it becomes classified as a dirk or dagger, which can only be legally carried openly in a sheath at the waist.

Fixed Blade Knives:

Fixed-blade knives, including hunting knives, tactical combat knives, Bowie-style blades, and other fixed-blade knives are legal to own and carry in California, provided they are worn openly and not concealed. However, they must be carried openly in a sheath that is visible, typically attached to the waist​.

Balisong (Butterfly) Knives:

Balisong or butterfly knives fall under the category of switchblades and are illegal to own or carry in California if their blade is 2 inches or longer​.

Prohibited Knife Types in California

Switchblades and Automatic Knives:

Switchblade knives, also known as automatic knives, are prohibited in California. These types of pocket knives open automatically with the press of a button or other mechanical device. The blades on these knives can be opened quickly and easily without manual manipulation of the blade itself. Any switchblade with a blade length of 2 inches or more is illegal​.

Ballistic (Throwing) Knives:

Ballistic (throwing) knives are illegal to own in California. These pocket knives have a detachable blade that is designed to be thrown at an object or person by releasing it from its handle. Throwing knives can cause serious injury if used improperly, and they are not allowed under state law​.

In California, it is important to be aware of the prohibited knife types that are illegal to own and carry. Additionally, there are age restrictions for knife ownership in the state as well.

Age Restrictions for Knife Ownership in California

The minimum age for purchasing and carrying a knife in California is indeed 18 years old. However, certain prohibited types of knives, such as switchblades, ballistic knives, and belt-buckle knives, are illegal to own or carry regardless of age​​.

Concealed Carry Laws for Pocket Knives in California

It’s illegal to carry a concealed dirk or dagger in California. However, folding knives can be carried both openly and concealed as long as they are in the folded position, regardless of blade length​.

Carrying fixed blades in a concealed manner is illegal.

Open Carry Laws for Pocket Knives in California

Open carry of knives is allowed in California, with the exception of switchblades, ballistic knives, and other prohibited knife types. Fixed-blade knives must be carried openly, and they must be in a visible sheath at the waist​.

Penalties for Violating Knife Laws in California

Violating knife laws in California can result in both misdemeanor and felony charges. Possession of a switchblade, for example, can lead to misdemeanor charges, punishable by up to 6 months in county jail and a fine of up to $1,000​. More serious offenses, such as carrying prohibited knives into public buildings or schools, may result in penalties of up to three years in state prison​.

Preemption Statutes Regarding Local Knife Regulations in California

California does not have a state-level preemption statute regarding knife laws. Local jurisdictions can enact their own knife laws, which might be stricter than the state law. For example, Los Angeles and Oakland prohibit carrying knives with blades 3 inches or longer in public, and San Francisco restricts loitering with a concealed knife that has a blade of 3 inches or more​. Therefore, it’s essential to check local laws in addition to the state laws before carrying a knife.
