What Is California Penal Code 16470 PC?

California Penal Code 16470 PC defines a dirk or dagger as a knife or other instrument capable of ready use as a stabbing weapon that may inflict great bodily injury or death.

The statute applies to more than traditional knives. Prosecutors may argue that many objects qualify as dirks or daggers if they are capable of use as stabbing weapons.

California Penal Code 16470 PC Definition

Under California law, a dirk or dagger includes:

Fixed-blade knives
Certain folding knives, when exposed and locked into position
Stabbing instruments
Sharp-edged weapons
Homemade stabbing devices
Certain tactical knives

California courts evaluate the design, condition, and accessibility of the object when determining whether it qualifies as a dirk or dagger.

Text of California Penal Code 16470 PC

California Penal Code 16470 PC states:

“As used in this part, ‘dirk' or ‘dagger' means a knife or other instrument, with or without a handguard, that is capable of ready use as a stabbing weapon that may inflict great bodily injury or death.”

The law further explains that a nonlocking folding knife, folding pocketknife, or utility knife is not considered a dirk or dagger when the blade is folded or retracted.

What Is Considered a Dirk or Dagger in California?

California prosecutors and courts broadly interpret what qualifies as a dirk or dagger.

Examples of Potential Dirks or Daggers

Objects that may qualify include:

Fixed-blade knives
Combat knives
Bowie knives
Ice picks
Certain folding knives
Tactical stabbing instruments
Homemade shanks
Double-edged knives
Concealed stabbing tools

Even everyday objects may be treated as illegal weapons if prosecutors believe they were intended or modified for stabbing use.

Folding Knives Under California Law

The blade is exposed
The blade locks into place
The knife is carried concealed

This distinction frequently becomes a central issue in criminal cases.
