Can You Carry a Folding Knife in California?  

California has strict knife laws, and carrying a folding knife can be legal or illegal depending on its design, blade length, and how it is carried. Understanding these regulations is crucial to avoid legal trouble. This article explores the key laws regarding folding knives in California, including permissible types, restrictions, and potential penalties for violations.  

1. Legal Types of Folding Knives in California  

Under California law, most non-locking folding knives (such as traditional pocket knives) are legal to carry as long as they are folded and concealed when carried in public. However, the legality changes if the knife meets certain criteria:  

-Switchblades (Automatic Knives): Illegal under Penal Code 21510, unless the blade is under 2 inches.  

– Gravity Knives & Balisongs (Butterfly Knives): Prohibited under Penal Code 21510, regardless of blade length.  

– Locking Folding Knives: While not explicitly banned, they may be considered “dirks” or “daggers” if the blade is fixed or easily opened with one hand, leading to legal risks.  

2. Blade Length Restrictions  

California does not have a strict statewide blade length limit for folding knives, but some local ordinances (e.g., Los Angeles and San Francisco) impose additional restrictions. Generally:  

– A folding knife with ablade under 2 inches is almost always legal.  

– Blades longer than 2 inches may be permitted if the knife does not lock and is carried folded.  

– Fixed-blade knives (including those concealed) are treated more strictly under Penal Code 21310.  

3. Concealed vs. Open Carry

– Concealed Carry: Non-locking folding knives can be carried concealed in a pocket or bag. However, carrying a locking knife concealed (especially one-handed opening) may be classified as carrying a “dagger,” which is illegal under Penal Code 21310.  

– Open Carry: Fixed-blade knives must be carried openly in a sheath, but folding knives are generally safer when folded and not visibly displayed.  

4. Prohibited Locations  

Even if a folding knife is legal, carrying it in certain places can result in criminal charges:  

– Schools & Government Buildings (Penal Code 626.10)  

– Airports & Secure Public Areas  

– Public Events with Security Checks  

5. Penalties for Violations  

Carrying an illegal knife (e.g., a switchblade or concealed dagger) can lead to:  

– Misdemeanor Charges: Up to 1 year in county jail and fines.  

– Felony Charges: If the knife is used in a crime or carried by a prohibited person (e.g., convicted felons).  

Conclusion  

In California, carrying a non-locking folding knife with a short blade is generally legal, but automatic knives, butterfly knives, and concealed locking knives can lead to serious legal consequences. Always check local ordinances and avoid carrying knives in restricted areas. When in doubt, opt for a simple pocket knife with a blade under 2 inches to stay compliant with the law.  

By understanding these regulations, knife owners can avoid unintended violations while exercising their right to carry a folding knife responsibly.
