What You Need to Know About California’s Knife Laws 

Can I Carry a Knife in California? 

The laws regarding possessing and carrying knives in California can be complicated. Although carrying a knife is not always illegal, carrying a weapon of any kind can increase your chances of trouble with law enforcement. Even if you are ultimately found to be acting within a legal context, you may still face the inconvenience of getting arrested, missing work, and paying any related fees. If you are planning to possess or carry certain types of knives, it is crucial to understand the laws surrounding them in order to avoid any criminal charges. 

Firstly, it is important to know which kinds of knives are legal to possess. California law considers certain knives to be dangerous weapons; these knives are illegal to own, sell, or manufacture. In general, illegal knives are those that are undetectable or misleading because they do not obviously look like knives and are commonly used to commit crimes. Knives that are illegal to possess in California include ballistic knives, cane knives, air gauge knives, lipstick knives, belt buckle knives, writing pen knives, switchblades with a blade of two inches or longer, and undetectable knives made from materials that cannot be detected by metal detectors. 

Even when some knives are legal to possess, there may be laws regulating how and if they can be carried openly. In general, folding knives can be carried openly or in a concealed position as long as they are in a closed position. California Penal Code Section 17235 defines a folding knife as a knife that opens with one hand utilizing thumb pressure applied solely to the blade of the knife or a thumb stud attached to the blade. These permissible knives include swiss army knives and pocket knives. 

California’s Knife Laws

On the other hand, some types of knives must be carried openly under California Penal Code Section 21310. This means that they cannot be concealed in a pocket, purse, backpack, or other container while in public. Rather, they may only be carried in a sheath worn on the carrier’s waist. The knives that are covered by this “open carry” law are called “dirks and daggers,” which include knives with fixed blades, stiletto knives, or even chef’s knives. Dirks and daggers must follow this special regulation because they can be readily used as a stabbing weapon and have the capacity to inflict great bodily injury or death. As such, the law tries to prevent surprise attacks by ensuring that anyone in close proximity to the knife carrier can clearly see the weapon. 

Penalties for Illegally Carrying a Knife 

Failing to comply with the aforementioned laws could lead to serious consequences. If you are caught in possessing, selling, or manufacturing a prohibited knife, the prosecution may charge the crime as either a misdemeanor or a felony. For a misdemeanor, you may face: 

  • Up to $1,000 in fines 
  • Up to 6 months or 1 year in county jail 

When charged as a more serious felony, you may face:

  • Up to $10,000 in fines 
  • 16 months to 3 years in county jail 

Carrying a concealed dirk or dagger can also be charged as either a misdemeanor or a felony. A misdemeanor charge is punishable by:

  • Up to $1,000 in fines 
  • Up to 1 year in county jail 

A felony charge is punishable by:

  • Up to $10,000 in fines 
  • 16 months to 3 years in county jail
