Throwing Knives in California: Not Specifically Banned
California's Penal Code does not include a specific prohibition on throwing knives as a category. Unlike switchblades or ballistic knives, the law doesn't target knives by their design for throwing. However, this doesn't mean throwing knives exist in a consequence-free legal zone.
Knife throwing is an ancient martial art and modern competitive sport with dedicated practitioners worldwide. In California, the legality involves navigating several overlapping statutes not written with throwing knives specifically in mind.
What the Law Actually Addresses
Several California statutes affect how throwing knives can be legally owned and used:
- Dirks and daggers (CPC § 16470): Any knife capable of ready use as a stabbing weapon. Many throwing knives fit this definition.
- Concealed carry prohibition (CPC § 21310): No person may carry concealed a dirk or dagger. Most throwing knives have fixed, double-edged blades.
- Open carry: Fixed-blade knives, including most throwing knives, can generally be carried openly in a sheath.
California law regulates knives based on functional characteristics rather than intended use. A throwing knife doesn't get special treatment simply because it was designed for sport.
The Dirk/Dagger Classification Problem
Most throwing knives have a fixed blade, a pointed tip designed for penetration, and a blade on one or both edges. This design easily qualifies as a "dirk or dagger" under California law.
Concealing such a knife — tucking it in a waistband, bag, or clothing — is a misdemeanor under CPC § 21310 that can escalate to a felony in certain circumstances.
Legal Use: Target Practice and Sport
Throwing knives at targets on private property or at licensed ranges is generally legal activity in California. The problems arise when you:
- Carry them concealed in public
- Throw them at or toward people
- Possess them in prohibited locations (schools, government buildings)
- Use them in a threatening manner
Transporting Throwing Knives
When transporting throwing knives in a vehicle, California law requires they be in a locked container. A dedicated knife case or bag placed in the trunk is safest. The knife should be completely enclosed and inaccessible from the passenger compartment.
Blade Length Considerations
While California doesn't have a statewide blade length limit for open carry, some municipalities restrict knives with blades longer than 3-4 inches. Throwing knives typically range from 6-12 inches, so check local ordinances.
Ballistic Knives: A Special Prohibition
California specifically bans ballistic knives (CPC § 21110) — knives with a blade propelled by a spring, explosive, or mechanical device. Always ensure any throwing knife is a simple, traditional design without mechanical projection mechanisms.
Competitive Knife Throwing in California
The American Knife Throwers Alliance (AKTA) and other organizations hold competitions throughout California. These events operate within the law by taking place on private property or at licensed facilities. Participants typically sign waivers and follow strict safety protocols. Organized competition provides a legal framework for enjoying the sport without legal risk.
Traditional throwing knives are legal to own in California and to use for sport on appropriate property. However, they likely qualify as dirks/daggers, making concealed carry illegal. Open carry in a visible sheath is the safest approach. Always check local ordinances for additional restrictions.
