Penal Code § 21310 PC - Dirk or dagger

1. What is Penal Code § 21310 PC?

Penal Code § 21310 PC defines the unlawful possession of a concealed dirk or dagger in California. This offense involves carrying a knife or blade that is capable of being used as a stabbing weapon in a manner that is concealed on the person. A conviction under this statute can result in serious penalties, depending on whether the charge is treated as a misdemeanor or felony.

What is Considered a Dirk or Dagger?

A “dirk” or “dagger” under California law refers to a blade or knife that is designed to be readily used as a stabbing weapon. These knives are typically double-edged and have a pointed tip, making them effective for stabbing. However, not all knives are classified as dirks or daggers. The law applies specifically to knives that are concealed on your person, and there are exceptions and nuances that determine whether a knife qualifies as a dirk or dagger.

For instance, folding knives or pocket knives are usually legal to carry, but only if they are closed and not locked into position. If a pocket knife is open or locked into place, it may be considered a dirk or dagger, and carrying it concealed would be a violation of Penal Code § 21310.

When is it a Crime to Carry a Dirk or Dagger?

For a prosecutor to successfully charge someone with violating Penal Code 21310 PC, they must prove the following four elements:

  1. The Defendant Carried a Dirk or Dagger: The individual must have had possession of a dirk or dagger.

  2. Knowledge of Possession: The defendant must have known they were carrying the knife.

  3. The Knife Was Concealed: The knife must have been hidden from view, typically under clothing, making it a concealed weapon.

  4. The Knife Could Be Used as a Weapon: The defendant must have known that the knife could be used as a stabbing weapon.

It’s important to note that prosecutors do not have to prove that the defendant intended to use the knife as a weapon or that the knife was used in an actual attack.

Penal Code § 21310 PC Law Reads As Followed:

“Any person in this state who carries upon the person a concealed dirk or dagger is guilty of a crime.”

2. What Are Examples of Penal Code § 21310 PC?

Penal Code § 21310 PC makes it illegal to carry a concealed dirk or dagger in California. This law specifically criminalizes the concealed possession of a knife or blade that is capable of being used as a stabbing weapon. The law defines a “dirk” or “dagger” as any knife or blade with a pointed tip, typically double-edged, that can be used to stab someone. If you are caught carrying such a weapon concealed on your person, you could be charged with a criminal offense.

In this article, we’ll explore some common examples of Penal Code § 21310 PC violations, to better understand how the law applies in real-life situations.

1. Carrying a Concealed Folding Knife

One of the most common examples of violating Penal Code § 21310 is carrying a concealed folding knife. While folding knives themselves are generally legal to possess, the law stipulates that if the knife is locked into place or the blade is exposed, it can be considered a dirk or dagger.

For example:

  • Example 1: John carries a folding knife in his pocket, but the blade is fully extended and locked into place. This means the knife can be easily used as a stabbing weapon, and because it is hidden in his pocket, it is a violation of Penal Code § 21310 PC.

  • Example 2: Sarah carries a similar folding knife in her bag, and the blade is open but not locked into place. As long as it’s not locked, it might not be classified as a dirk or dagger. However, if it were locked or if it were in a position that could be easily used to stab someone, Sarah would also be breaking the law by carrying it concealed.

2. Concealed Stiletto Knife

A stiletto knife is a type of dagger known for its thin, pointed blade designed for stabbing. If someone carries a stiletto knife hidden under their clothing or in a concealed pocket, they would be violating Penal Code § 21310. This is because the stiletto knife fits the definition of a dirk or dagger and is ready for use as a stabbing weapon.

For example:

  • Example 3: Mark is stopped by police while walking down the street. He has a stiletto knife tucked inside his jacket pocket. Since the knife is hidden from view and can be easily used as a stabbing weapon, he would be arrested for violating Penal Code § 21310 PC.

3. Carrying a Dagger in a Hidden Compartment

Another example involves carrying a dagger or a knife with a blade that is typically designed for stabbing, tucked away in a hidden compartment. This could be a concealed compartment in a backpack, briefcase, or even a specially designed sheath that keeps the weapon out of sight.

For example:

  • Example 4: Laura has a concealed dagger inside a compartment of her purse that she regularly carries. The dagger is completely hidden from view, and she knows it’s there. Because the weapon is hidden and capable of being used as a stabbing weapon, Laura could face criminal charges under Penal Code § 21310.

4. Concealed Weapon in a Vehicle

A dirk or dagger can also be considered a concealed weapon if it’s carried in a vehicle. California law applies to anyone carrying a concealed dirk or dagger on their person, but it can also apply to anyone carrying such a weapon in their vehicle if the weapon is hidden and accessible.

For example:

  • Example 5: Jack keeps a concealed dagger in the glove compartment of his car. Although he is not physically carrying it on his person, the dagger is still considered concealed within his vehicle, and he could be arrested for violating Penal Code § 21310 if he is stopped by law enforcement.

5. Wearing a Dagger Hidden in Clothing

Some people may attempt to conceal a dirk or dagger within their clothing, either by hiding it in their belt or under layers of fabric. In California, wearing a concealed weapon like this is still considered a violation of the law.

For example:

  • Example 6: Tanya wears a long jacket with the intention of concealing a small dagger hidden under the folds. The dagger is not visible to others, and Tanya knows it is there, making it a concealed weapon. If she is stopped by police or searched, she could be arrested for violating Penal Code § 21310.

6. Carrying a Concealed Taser Knife

Some knives are designed to resemble a tactical pen, flashlight, or taser while also having a concealed knife or blade inside. If someone is carrying such a hybrid weapon, the knife portion of it may be considered a dirk or dagger under Penal Code § 21310.

For example:

  • Example 7: Kevin carries a taser pen with a hidden blade. He knows the blade is there and keeps it concealed in his coat pocket. In this case, the taser pen may contain a blade that qualifies as a dirk or dagger, and Kevin could face charges under Penal Code § 21310 if it’s concealed.

7. Police Officer Finds a Concealed Dagger During an Illegal Search

While carrying a concealed dirk or dagger is illegal, certain circumstances could involve law enforcement finding the weapon during an illegal search or without a valid warrant. Even in such cases, the defendant could argue that the knife should not be considered evidence.

For example:

  • Example 8: Tom is walking down the street, and a police officer stops him because of a previous encounter. The officer searches him without probable cause and finds a concealed dagger. Tom could argue that the search was unlawful, and the evidence should be suppressed in court. If the court finds the search was illegal, the charge under Penal Code § 21310 could be dismissed.

3. What are Common Defenses Against Penal Code § 21310 PC?

Penal Code § 21310 PC makes it a crime to carry a concealed dirk or dagger in California. A dirk or dagger refers to a knife or blade with a pointed tip that is capable of being used as a stabbing weapon. If you are accused of violating this law, there are several common defenses that could be raised to fight the charges. Understanding these defenses is important, as they can help reduce or even dismiss charges against you.

In this article, we’ll discuss some of the most common defenses against Penal Code § 21310 PC charges and how they might be used in your case.

1. The Knife Was Not a Dirk or Dagger

One of the most common defenses against Penal Code § 21310 PC is proving that the weapon in question is not a dirk or dagger under California law. To be classified as a dirk or dagger, a knife must meet specific criteria, including being a blade that is capable of being used as a stabbing weapon.

  • What does this defense look like? If the knife was a pocket knife, folding knife, or a tool with a blade that does not lock into place, it may not qualify as a dirk or dagger. The knife might be non-locking or not exposed at the time of the alleged offense.

    • Example: Mark carries a folding knife in his pocket, but it is closed and not locked into position. As such, the knife does not meet the statutory definition of a dirk or dagger, and he cannot be convicted under Penal Code § 21310.

    This defense may require the testimony of a weapons expert who can confirm that the knife in question does not meet the legal criteria of a dirk or dagger.

2. You Were Not Carrying the Dirk or Dagger Concealed

Penal Code § 21310 PC only applies if the dirk or dagger is concealed. This means that if the weapon was carried openly, such as in a sheath attached to your waist, you may not be guilty of violating the law.

  • What does this defense look like? If you were carrying a dirk or dagger in a sheath that was clearly visible, or if the weapon was worn on the outside of your clothing, it could be considered open carry, which is legal under California law.

    • Example: Julie carries a dirk in a sheath attached to her belt. The knife is clearly visible to anyone who looks at her. Since the weapon was openly carried, she would not be guilty under Penal Code § 21310.

This defense may be supported by witness testimony, video footage, or other evidence that shows the weapon was carried openly and not concealed.

3. The Police Found the Weapon Through an Unlawful Search and Seizure

If the police conducted an illegal search or seizure and found the concealed weapon, it may be possible to challenge the evidence based on a violation of your constitutional rights. According to the Fourth Amendment, the police cannot stop and search a person without reasonable suspicion or a search warrant, unless there are certain exceptions.

  • What does this defense look like? If the police stopped you or searched your belongings without a valid reason or probable cause, they may have violated your rights. In such a case, the evidence (in this case, the dirk or dagger) could be excluded from court.

    • Example: Tom is walking down the street when a police officer stops him without reasonable suspicion and frisks him. During the search, the officer finds a concealed dagger in Tom’s jacket pocket. Since the officer did not have probable cause to stop and search Tom, the evidence may be inadmissible, and the charges could be dropped.

If this defense is successful, it may lead to a motion to suppress the evidence, which could result in the dismissal of the charges.

4. You Were Carrying the Dirk or Dagger for a Lawful Purpose

While self-defense is not a defense to Penal Code § 21310 PC, if you can demonstrate that you were carrying the weapon for a lawful reason, such as for work, hunting, or recreational purposes, this may be used as part of your defense strategy.

  • What does this defense look like? You may argue that the dirk or dagger was being carried for a legitimate purpose and not for criminal intent. For example, a person who works in a trade where knives are necessary might be able to prove that carrying the weapon was not for illegal purposes.

    • Example: Harry is a construction worker who carries a knife for work purposes. The knife is concealed in his tool belt. While it is concealed, the knife is essential for his job, and he can argue that it was being carried for lawful reasons.

However, it’s important to note that California law still prohibits carrying certain types of knives in public, even for lawful purposes, unless the weapon is being carried openly or is not concealed.

5. The Police Mistook the Weapon for Another Object

In some cases, the police may misidentify an item as a dirk or dagger. If the item in question was not a knife or blade but something else entirely, this could be used as a defense.

  • What does this defense look like? If you were carrying a legitimate tool, such as a multi-tool or utility knife, that could have been mistaken for a dirk or dagger, you may be able to argue that the police misidentified it.

    • Example: Susan is carrying a multi-tool that has a small, non-locking blade as part of its set. When she is stopped by the police, they mistakenly identify the tool as a concealed dirk. By explaining the true nature of the object and its intended use, Susan can demonstrate that the police made an error in judgment.

6. Lack of Knowledge or Intent

In some cases, the defendant may not have known that they were carrying a dirk or dagger, or they may not have had the intent to carry it concealed.

  • What does this defense look like? If you can show that you were unaware that you were carrying a concealed weapon, or that you did not intend to carry it in that manner, you may be able to argue that there was no criminal intent. This defense is often used when the person did not realize that the weapon was concealed or ready for use.

    • Example: Brian is carrying a knife in his backpack and did not realize it was in a concealed position. If he can show that he did not know the knife was hidden, it could be argued that there was no intent to violate Penal Code § 21310.

4. What are The Penalties for Violating Penal Code § 21310 PC?

Penal Code § 21310 PC makes it illegal to carry a concealed dirk or dagger in California. A dirk or dagger is typically defined as a knife or blade that is capable of being used as a stabbing weapon. California law prohibits carrying such weapons in a concealed manner, meaning they are hidden from view on your person. Violating this law can lead to significant legal consequences, and the penalties depend on whether the charge is classified as a misdemeanor or felony.

In this article, we will explain the penalties associated with violating Penal Code § 21310 PC, and how the charges could be handled in court.

1. Misdemeanor Penalties

In California, the crime of carrying a concealed dirk or dagger is considered a wobbler offense. This means the prosecutor has the discretion to charge the offense as either a misdemeanor or a felony, depending on the circumstances of the case and the defendant’s criminal history.

If you are charged with a misdemeanor violation of Penal Code § 21310 PC, the potential penalties may include:

  • Misdemeanor probation: This means you would be placed under supervision in the community instead of being sent to jail. During probation, you may be required to follow specific conditions, such as attending counseling or performing community service.

  • County jail time: A misdemeanor conviction under Penal Code § 21310 PC can result in up to one year in county jail. Jail time is often seen as the last resort for misdemeanor offenses, but it is still a possibility for those convicted.

  • Fines: A misdemeanor conviction can result in a fine of up to $1,000. This fine is imposed in addition to any other penalties, such as jail time or probation.

  • Criminal record: A misdemeanor conviction will result in a criminal record, which could have long-term consequences, such as affecting employment opportunities, housing, and other aspects of life.

2. Felony Penalties

If you are charged with a felony violation of Penal Code § 21310 PC, the penalties become significantly more severe. Factors such as your prior criminal history, the circumstances surrounding the offense, and whether the prosecutor believes that a felony conviction is justified, can all play a role in determining whether the charge is treated as a felony.

The penalties for a felony conviction under Penal Code § 21310 PC can include:

  • Felony probation: Felony probation, also known as formal probation, is a form of supervision where you are required to comply with strict conditions imposed by the court. This could include things like regular check-ins with a probation officer, attending counseling, performing community service, and paying fines or restitution.

  • County jail time: A felony conviction can result in up to three years in county jail. While prison is not usually an option for felonies under this statute (since it is a county jail offense), three years in county jail is a significant sentence that can severely impact your life.

  • Fines: A felony conviction for violating Penal Code § 21310 PC can lead to a fine of up to $10,000. This is a substantial amount and can place significant financial strain on someone convicted of this offense.

  • Criminal record: A felony conviction will result in a permanent criminal record, which can make it difficult to find employment, obtain housing, or even retain professional licenses in certain fields. Felony convictions also carry other long-term consequences, including the potential loss of civil rights, such as the right to vote or possess firearms.

3. Factors That Can Influence the Penalties

While the penalties for violating Penal Code § 21310 PC are outlined above, there are certain factors that could influence whether you are charged with a misdemeanor or felony, as well as the severity of the sentence:

  • Prior Criminal History: If you have a history of prior criminal convictions, especially for weapons-related offenses, you may face harsher penalties. The prosecutor may be more likely to pursue felony charges, or you may receive a more severe sentence if convicted.

  • Circumstances of the Arrest: If the concealed dirk or dagger was found during an arrest for another crime, or if there were aggravating factors (such as possession of other illegal weapons), this could result in a more severe charge and penalties.

  • The Type of Weapon: The type of dirk or dagger you were carrying may influence the penalty. For example, if the weapon was considered particularly dangerous or designed for illegal use, this could lead to increased penalties.

  • Plea Bargaining: In some cases, you may be able to negotiate a plea deal with the prosecutor, resulting in reduced charges or lesser penalties. This is common in criminal cases, especially if the defendant is willing to cooperate with law enforcement or take responsibility for the offense.

4. Impact of a Conviction on Your Rights

In addition to the criminal penalties, a conviction under Penal Code § 21310 PC can have lasting effects on other aspects of your life:

  • Firearm Rights: If convicted of a felony, you will lose your right to possess or own a firearm. This is a serious consequence for anyone who relies on firearms for hunting, self-defense, or recreation.

  • Immigration Consequences: If you are not a U.S. citizen, a conviction under Penal Code § 21310 PC could have immigration consequences. A felony conviction may result in deportation or difficulty obtaining citizenship, while a misdemeanor conviction may still lead to problems in the immigration process.

  • Employment and Education: A conviction, whether felony or misdemeanor, can impact your ability to find a job or enroll in school. Many employers and educational institutions conduct background checks, and a criminal record may limit your opportunities.

5. Possibility of Expungement

One potential way to reduce the long-term impact of a conviction for violating Penal Code § 21310 PC is expungement. In California, it is possible to have a misdemeanor conviction expunged, meaning it would be removed from your criminal record. However, for felony convictions, expungement is more challenging and may only be possible after certain conditions are met, such as successful completion of probation and no further criminal activity.

Expungement allows individuals to move forward with their lives without the hindrance of a criminal record, but it is important to consult with an experienced attorney to understand the process and whether you are eligible.

5. What Are the Related Offenses To Penal Code § 21310 PC?

Penal Code § 21310 PC makes it a crime to carry a concealed dirk or dagger in California. A dirk or dagger refers to a type of knife or blade that is designed to be used as a stabbing weapon. Carrying such a weapon in a concealed manner is considered illegal under this statute, and individuals found guilty of violating this law can face serious legal consequences.

In addition to Penal Code § 21310, there are several related offenses that involve the unlawful possession, use, or carrying of dangerous weapons, including knives, blades, and other firearms. Understanding these related offenses is important for anyone who may be facing weapon-related charges or who wants to understand California’s broader legal framework for weapons crimes.

1. Penal Code § 16590 PC – Possession of Dangerous Weapons

Penal Code § 16590 PC prohibits the possession, sale, manufacture, or importation of certain dangerous weapons in California. This includes items such as:

  • Ballistic knives

  • Bowie knives

  • Throwing stars

  • Blackjacks

  • Brass knuckles

  • Undetectable knives or weapons

While Penal Code § 21310 PC deals specifically with concealed dirks and daggers, Penal Code § 16590 is broader, covering a wide range of dangerous weapons that are illegal to possess in California.

  • Related Example: If someone is found carrying a brass knuckle knife—a combination of a weapon and a tool—it may fall under both Penal Code § 21310 PC and Penal Code § 16590 PC, depending on whether it is concealed and the circumstances of possession.

2. Penal Code § 171b PC – Possessing Weapons in Public Buildings

Penal Code § 171b PC makes it a crime to carry certain prohibited weapons, including dirks and daggers, into public buildings in California. This statute applies to public places such as:

  • State offices

  • Government buildings

  • Public schools

  • Courthouses

If you are carrying a concealed dirk or dagger into one of these areas, you could be charged with a violation under this statute, in addition to a potential violation of Penal Code § 21310 PC.

  • Related Example: If you are stopped at a courthouse security checkpoint and found with a concealed dagger in your bag, you could face charges under both Penal Code § 21310 (for carrying the concealed weapon) and Penal Code § 171b (for possessing it in a public building).

3. Penal Code § 626.10 PC – Possessing Dangerous Weapons on School Grounds

Penal Code § 626.10 PC criminalizes the act of carrying dirks, daggers, or other dangerous weapons onto school grounds, including public and private K-12 schools and college campuses. This offense is classified as a wobbler, meaning it could be charged as either a misdemeanor or felony, depending on the specific circumstances.

The statute explicitly prohibits the possession of:

  • Dirks

  • Daggers

  • Switchblades

  • Nunchaku

  • Stun guns

  • Related Example: If a student brings a concealed dirk to school in their backpack, they could be charged under Penal Code § 626.10 PC for possessing the weapon on school grounds, in addition to any violation of Penal Code § 21310 PC if the weapon is concealed.

4. Penal Code § 417 PC – Brandishing a Weapon

Penal Code § 417 PC prohibits the act of brandishing a weapon, including a dirk or dagger, in a threatening manner. Brandishing occurs when someone displays a weapon in a way that threatens another person or causes them to reasonably fear harm.

  • Related Example: If someone pulls out a concealed dirk or dagger and points it at another person in a threatening way, they could be charged under Penal Code § 417 for brandishing a weapon, as well as under Penal Code § 21310 for carrying the weapon concealed.

Brandishing a weapon is typically considered a misdemeanor, but in certain circumstances, it could be charged as a felony, especially if there is a threat of violence or injury.

5. Penal Code § 21510 PC – Carrying a Switchblade

Penal Code § 21510 PC makes it illegal to carry a switchblade knife in California. A switchblade is a type of knife that opens automatically with the press of a button or other mechanism. Unlike a dirk or dagger, a switchblade knife is designed for quick deployment, and it is therefore treated differently under the law.

  • Related Example: If you are caught with a concealed switchblade in addition to a dirk or dagger, you could face charges under Penal Code § 21510 PC for carrying the switchblade and Penal Code § 21310 PC for carrying the concealed dirk or dagger.

6. Penal Code § 245(a)(1) PC – Assault with a Deadly Weapon

Penal Code § 245(a)(1) PC criminalizes the act of assaulting someone with a deadly weapon, such as a dirk, dagger, or other sharp objects. Assault with a deadly weapon is a serious criminal offense and is punishable by severe penalties, including significant jail or prison time.

  • Related Example: If you use a dirk or dagger to threaten or injure another person, you could face charges under Penal Code § 245(a)(1) PC for assault with a deadly weapon, in addition to being charged under Penal Code § 21310 PC for carrying the concealed weapon.

Assault with a deadly weapon can be classified as either a misdemeanor or a felony, depending on the severity of the crime and whether the defendant has a criminal record.

7. Penal Code § 12020 PC – Possessing Concealed Weapons

Penal Code § 12020 PC makes it a crime to possess various types of concealed weapons, including knives, guns, and other dangerous objects. This statute provides additional legal coverage for situations where an individual is found with a concealed weapon, and it can apply to a wide range of prohibited items, including dirks and daggers.

  • Related Example: If you are found with a concealed dirk or dagger, you could face charges under Penal Code § 12020 PC, along with charges under Penal Code § 21310 PC. This offense is considered a wobbler, meaning it can be charged as either a misdemeanor or felony.
