What Is California Penal Code 21110 PC?

California Penal Code 21110 PC prohibits manufacturing, importing into California, selling, giving, lending, or possessing ballistic knives.

Under California law, ballistic knives are dangerous weapons capable of expelling knife blades through mechanical force or explosive action. The law broadly criminalizes both commercial activity and personal possession involving these prohibited weapons.

California lawmakers classify ballistic knives as dangerous concealed weapons because they can rapidly deploy blades as projectiles capable of causing serious bodily injury or death.

Text of California Penal Code 21110 PC

California Penal Code 21110 PC states in substance that any person who manufactures, imports into the state, keeps for sale, offers for sale, exposes for sale, gives, lends, or possesses a ballistic knife is guilty of a criminal offense.

The statute applies regardless of whether the weapon is actually used or displayed publicly.

What Is a Ballistic Knife?

A ballistic knife is generally a knife with a detachable blade that may be expelled or launched through:

Spring-loaded mechanisms
Compressed gas
Explosive force
Mechanical propulsion systems

Unlike ordinary knives, ballistic knives are specifically designed to project their blades outward as weapons.

Examples may include:

Spring-propelled knife launchers
Military-style ballistic knives
Projectile blade weapons
Mechanically launched knife devices

California law treats these weapons differently from ordinary folding knives or fixed-blade knives.

Why California Prohibits Ballistic Knives

California weapon laws prohibit ballistic knives because lawmakers consider them especially dangerous and difficult to control.

Public safety concerns include:

Concealed weapon risks
Rapid projectile deployment
Increased lethality
Difficulty detecting concealed weapons
Potential use during violent crimes
Risks to law enforcement officers

Ballistic knives are often categorized alongside other prohibited weapons under California law.
