Ballistic Knives: California Penal Code 21110 PC

California enforces some of the nation's strictest weapon prohibitions. Under Penal Code 21110 PC, it is a criminal offense to manufacture, import, sell, give, lend, or possess a ballistic knife within the state.

Ballistic knives are heavily restricted because they are engineered to launch a detachable blade as a projectile using mechanical propulsion, compressed gas, or spring-loaded actions.

Even if you keep the item purely as a collectible or never display it publicly, simple possession can trigger misdemeanor charges, county jail time, steep fines, weapon confiscation, and a permanent criminal record.

If you are under investigation or facing weapons charges in Southern California, protecting your freedom requires immediate, strategic defense representation. The criminal defense attorneys at Cron, Israels & Stark are here to help.

What Is California Penal Code 21110 PC?

Penal Code 21110 broadly criminalizes both commercial activity and personal ownership involving ballistic knives. Specifically, the statute prohibits any person from:

• Manufacturing or assembling ballistic knives.

• Importing ballistic knives into California.

• Keeping, offering, or exposing ballistic knives for sale.

• Selling, giving, or lending a ballistic knife to another person.

• Possessing a ballistic knife.

What Is a Ballistic Knife Under California Law?

Defined further under Penal Code 17240, a ballistic knife is any knife with a detachable blade that can be expelled or launched outward as a projectile using:

• Spring-loaded mechanisms or tension systems

• Compressed gas or pneumatic propulsion

• Explosive force or mechanical devices

Unlike ordinary pocket knives, folding knives, or fixed-blade hunting knives, California lawmakers treat ballistic knives as inherently dangerous concealed projectile weapons that pose severe safety risks to the public and law enforcement officers.

Penalties and Consequences of a PC 21110 Conviction

Violating Penal Code 21110 is generally prosecuted as a misdemeanor, but the collateral and direct penalties can severely disrupt your life.

Penalty Type	Potential Consequences & Impact
Criminal Charges	Generally prosecuted as a misdemeanor offense resulting in a permanent record.
Jail Sentence	Up to 1 year in county jail.
Fines & Fees	Court-imposed financial penalties and mandatory assessment fees.

Immigration Penalties	Non-citizens face severe federal risks, including visa denials, green card complications, and deportation proceedings.

Common Legal Defenses to PC 21110 Charges

An experienced criminal defense strategy scrutinizes the physical evidence, the circumstances of the seizure, and the statutory definitions. Common defenses include:

• The Object Is Not a Ballistic Knife: Arguing that the seized item does not legally qualify as a ballistic knife under California statutory definitions (e.g., novelty items, standard multi-tools, or modified pocket knives).

• Lack of Knowledge: The prosecution must prove you knowingly possessed or controlled the weapon. If a ballistic knife was left in your vehicle or home by someone else without your knowledge, this serves as a valid defense.

• Unlawful Search and Seizure (Fourth Amendment Violations): If law enforcement found the weapon during an illegal traffic stop, unlawful detention, or unconstitutional search of your property, defense counsel can move to suppress the evidence, often leading to dismissal.

• Temporary Possession for Surrender: Proving that possession was strictly temporary and intended solely for lawful surrender or disposal to authorities.
