California Penal Code Section 21510 PC: Carrying A Switchblade (2024)

1. Definition and Elements of the Crime

Because of how easily they can be concealed, switchblade knives are considered to be highly effective weapons. As a result, carrying a switchblade on one’s person or in one’s vehicle or offering to sell or provide a switchblade to another person is a criminal offense under California Penal Code Section 21510 PC.

To prove that a defendant is guilty of carrying or providing a switchblade, the prosecutor must be able to establish the following elements:

The defendant possessed or offered to sell or provide a switchblade knife
The blade of the knife was two or more inches long
The defendant did this knowingly
AND the defendant knew that the knife had the characteristics of a switchblade.

A switchblade knife is defined as a knife that looks like a pocketknife and has a blade that can be released automatically by a flick of a button, pressure on the handle, flip of the wrist or other mechanical device, or is released by the weight of the blade or any other mechanism. Spring-blade knives, snap-blade knives, gravity knives and butterfly knives are all considered switchblades under the statute.

A man buys a spring-loaded knife that opens automatically when he presses a button. The blade is over two inches long and the man keeps the knife in his automobile. The man could be prosecuted for carrying a switchblade in violation of California Penal Code Section 21510 PC.

In another example, a man carries a fishing knife on him that folds in and can be concealed. While the swinging mechanism of the blade is stopped by a divot in the blade, the knife can be opened quickly with a strong flick of the wrist. This man would not be guilty under California Penal Code Section 21510 PC because even though the knife is capable of being quickly flipped open, it does contain a mechanism that keeps it closed and is exempt under the law.

4. Defenses to Carrying a Switchblade

If the knife in question does not meet the statutory definition of a switchblade, the defendant could not be prosecuted for this offense. Additionally, if the defendant did not know that he or she was carrying a switchblade, he or she would not be criminally liable under the statute.

If the switchblade was found during an illegal search and/or seizure, the defendant may be able to challenge whether the officer had sufficient probable cause to search the defendant or seize the knife. If successful, the switchblade would be suppressed and the prosecutor would be unable to proceed.

5. Penalties

Carrying a switchblade knife is a misdemeanor offense that is punishable by up to six months in jail, a $1,000 fine, forfeiture of the switchblade and any other conditions of probation that a judge may deem appropriate.
