Yes, California generally permits butterfly knives (balisongs) under state law, but local ordinances and concealed carry restrictions apply. While Penal Code § 21510 bans switchblades, balisongs are not classified as such. However, cities like Los Angeles and San Francisco impose additional prohibitions, and open carry in public remains subject to local discretion.
Key Regulations for Butterfly Knives (Balisongs) in California
- Local Bans: Municipalities such as Los Angeles and San Francisco prohibit possession of balisongs in public spaces, with penalties ranging from fines to misdemeanor charges under municipal codes.
- Concealed Carry Restrictions: Transporting a balisong in a vehicle without a secure sheath or locked container violates Vehicle Code § 25400, risking felony charges if deemed accessible.
- 2026 Compliance Shifts: Pending Assembly Bill 1594 (effective 2026) may reclassify balisongs as “dirks/daggers” if blade length exceeds 2.5 inches, subjecting them to concealed carry prohibitions under Penal Code § 21310.
Penalties for violations include fines up to $1,000 and imprisonment up to one year, depending on local enforcement. The California Department of Justice’s 2024 Firearm & Knife Laws Bulletin emphasizes that intent to use a balisong as a weapon can elevate charges to aggravated assault under Penal Code § 245.
