Dirks and Daggers: Penal Code 16470 PC & PC 21310

California Penal Code 16470 PC defines a "dirk" or "dagger" under state law. This definition is critical because under California Penal Code 21310 PC, carrying a concealed dirk or dagger is a serious criminal offense that can be prosecuted as either a misdemeanor or a felony (a "wobbler").

Because California knife laws combine strict statutory definitions with complex rules regarding concealment, folding mechanisms, and police search procedures, navigating an arrest requires immediate legal defense.

The experienced criminal defense attorneys at Cron, Israels & Stark represent clients facing weapons allegations throughout Southern California.

What Is California Penal Code 16470 PC?

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

The statute applies far beyond traditional daggers, encompassing a wide array of sharp-edged tools, tactical instruments, and homemade weapons.

Legal Definition Under the Statute

Under the law, a dirk or dagger includes:

• Fixed-blade knives, hunting knives, and combat daggers.

• Certain folding knives only when the blade is exposed and locked open.

• Stabbing instruments, ice picks, and sharpened metal spikes.

• Homemade shanks and improvised stabbing devices.

The Folding Knife Exception: Under PC 16470, a nonlocking folding pocketknife, pocketknife, or standard utility knife is not considered a dirk or dagger when the blade is completely folded or retracted. However, if a folding knife is carried in public with the blade locked open and concealed, prosecutors will routinely treat it as an illegal dirk or dagger.

Penal Code 21310 PC: Carrying a Concealed Dirk or Dagger

While owning a fixed-blade knife is not inherently illegal in California, carrying it concealed on your person violates Penal Code 21310 PC.

What Prosecutors Must Prove

To secure a conviction, the prosecution must establish the following elements beyond a reasonable doubt:

• The defendant carried a dirk or dagger on their person.

• The weapon was substantially concealed from ordinary view.

• The defendant knew that the weapon was present and accessible.

• The object was capable of ready use as a stabbing weapon. (Note: Prosecutors do not need to prove intent to use the weapon unlawfully).

What Counts as "Concealed"?

A weapon is considered legally concealed if it is hidden from ordinary observation, including being tucked into a waistband under a shirt, carried inside a jacket pocket, hidden inside a purse or backpack, or tucked into an accessible spot within a vehicle. Even partial concealment can trigger criminal charges.

Penalties and Sentencing for PC 21310 Violations

Because carrying a concealed dirk or dagger is a wobbler offense, district attorneys can charge the crime as either a misdemeanor or a felony based on the circumstances of the arrest and the defendant's criminal record.

Charge Level	Potential Penalties & Consequences
Misdemeanor Violation	Up to 1 year in county jail, summary probation, and fines up to $1,000.
Felony Violation	16 months, 2 years, or 3 years in state prison or county jail under realignment, formal probation, and fines up to $10,000.
Collateral Consequences	Permanent criminal record, loss of Second Amendment firearm rights, employment barriers, housing hurdles, and potential federal immigration consequences (deportation or inadmissibility) for non-citizens.

Common Legal Defenses to Dirk and Dagger Charges

An aggressive criminal defense strategy can challenge the foundation of the prosecution's case. Effective defenses include:

• The Object Was Not a Dirk or Dagger: Arguing that the item does not legally qualify as a stabbing weapon under statutory definitions (e.g., utility tools or folded pocketknives).

• The Weapon Was Not Concealed: Proving that the knife was openly carried in plain view, which removes the violation from the scope of PC 21310.

• Lack of Knowledge: Establishing that the defendant did not know the weapon was in their clothing, bag, or vehicle.

• Unlawful Search and Seizure (Fourth Amendment Violations): If law enforcement discovered the knife during an unconstitutional traffic stop, illegal detention, or warrantless search, defense counsel can move to suppress the evidence, frequently resulting in a dismissal.

Frequently Asked Questions (FAQs)

Is carrying a knife illegal in California?

No. California law permits the open carry or legal possession of many standard utility knives, pocketknives, and folding knives, provided they are not concealed dirks, daggers, or prohibited automatic switchblades.

Is a pocketknife considered a dirk or dagger under California law?

Generally, a folding pocketknife is exempt from the dirk or dagger law when folded closed. However, if the folding knife is locked open and concealed on a person, prosecutors may legally classify it as a dirk or dagger.

Can a concealed knife charge be filed as a felony?

Yes. Because Penal Code 21310 is a wobbler offense, prosecutors can file it as either a misdemeanor or a felony depending on the case facts and prior criminal history.

Can knife charges be dismissed in court?

Yes. Criminal defense attorneys often secure dismissals or charge reductions by challenging unlawful police searches, contesting weapon classifications, or showing a lack of concealment.

What immigration risks are associated with a weapon conviction?

Non-citizens convicted of certain felony weapon offenses face severe federal immigration consequences, including mandatory deportation proceedings, visa denials, and permanent inadmissibility.
