Arizona Knife Laws (2026) – What You Can Legally Carry

Overview of Arizona Knife Laws in 2026

Arizona is widely regarded as one of the most knife-friendly states in America. The state places virtually no restrictions on knife ownership and has extremely permissive carry laws for adults aged 21 and older. With statewide preemption preventing local governments from creating their own knife restrictions, Arizona provides a uniform and predictable legal framework for knife owners across the entire state.

Whether you are an EDC enthusiast in Phoenix, a rancher in rural Arizona, or a tourist visiting the Grand Canyon, understanding Arizona’s knife laws ensures you stay compliant while exercising your right to carry.

Legal Definitions Under Arizona Law

Arizona’s primary knife law is found in ARS § 13-3102, titled “Misconduct involving weapons; defenses; classification; definitions.” The statute restricts the concealed carry of a “deadly weapon,” which is defined as “anything designed for lethal use, including a knife.” Additionally, ARS § 13-3101 defines a “prohibited weapon” but no knives fall into this category.

The key distinction in Arizona law is between a “pocket knife” and other knives. A pocket knife (a folding knife with a blade that folds into the handle) is generally not considered a “deadly weapon” for concealed carry purposes, meaning even persons under 21 may carry one concealed.

What Knives Are Legal to Own in Arizona?

Arizona places no restrictions whatsoever on knife ownership. You may legally own any type of knife, including:

• Switchblades and automatic knives — Fully legal (restrictions were removed in 2011)
• Butterfly knives (balisongs) — Legal
• Bowie knives — Legal
• Dirks, daggers, and stilettos — Legal
• OTF (out-the-front) knives — Legal
• Machetes and swords — Legal
• Fixed-blade knives of any size — Legal
• Folding knives and pocket knives — Legal
• Throwing knives — Legal
• Gravity knives — Legal

Arizona removed its switchblade ban in 2011, making it one of the first states in the modern era to fully legalize automatic knives.

Open Carry of Knives in Arizona

Open carry of any knife is completely unrestricted in Arizona for persons of all ages. There is no age requirement, no blade length limit, and no restriction on knife type for open carry. Whether you’re carrying a large Bowie knife, a machete, or a sword, open carry is legal throughout the state.

This makes Arizona particularly friendly for hikers, campers, and outdoor enthusiasts who routinely carry large knives for practical purposes.

Concealed Carry of Knives in Arizona

Arizona’s concealed carry rules for knives are age-dependent:

• Age 21 and older: May carry any knife concealed without a permit. This includes switchblades, large fixed blades, and any other type of knife.
• Under age 21: May carry a pocket knife concealed. However, concealed carry of other “deadly weapons” (such as large fixed-blade knives, switchblades, or daggers) is restricted without a concealed weapons permit.

Arizona is a constitutional carry state, meaning no permit is required for concealed carry of weapons (including knives) by those 21 and older. Permits are available for those who want one, which may provide reciprocity benefits in other states.

Blade Length Restrictions

Arizona has no blade length limit at either the state or local level. The statewide preemption law prevents any municipality from imposing blade length restrictions. You may carry a knife of any blade length, whether openly or concealed (if you meet the age requirement for concealed carry).

Statewide Preemption

Arizona has strong statewide knife preemption under ARS § 13-3120. This statute establishes that the state has sole authority to regulate the carrying of knives, preventing local governments from enacting conflicting regulations. This means the laws are the same in Phoenix, Tucson, Flagstaff, Scottsdale, and every other city in the state.

This is a major advantage for knife carriers who travel within Arizona, as there is no patchwork of local ordinances to navigate.

Restricted Locations

Even in knife-friendly Arizona, certain locations restrict the carry of weapons including knives:

• Schools (K-12): Possession of a deadly weapon on school grounds is prohibited under ARS § 13-3102. This includes all knives except possibly a small pocket knife used as a tool.
• Polling places on election day: Weapons are restricted within 75 feet of a polling place during an election.
• Nuclear or hydroelectric generating stations: Weapons are prohibited.
• Secured areas of airports: Knives are prohibited past security checkpoints per federal law.
• Government buildings with security screening: If a building has security screening, weapons may be restricted.
• Private property: Property owners may prohibit weapons on their premises.

Age Restrictions

While Arizona does not restrict knife ownership by age, concealed carry of “deadly weapons” is limited to those 21 and older unless the person has a concealed weapons permit. There are no specific age restrictions on the purchase of knives in Arizona, though individual retailers may set their own policies.

Recent Changes to Arizona Knife Law

Arizona’s knife laws have been stable since the major reforms of 2010-2011, when the state:

• Legalized switchblades and automatic knives (2011)
• Enacted statewide knife preemption
• Adopted constitutional carry for those 21+

As of February 2026, no significant new knife legislation has been enacted. Arizona continues to be cited as a model for knife-friendly legislation across the United States.

Penalties for Knife Law Violations

• Misconduct involving weapons (ARS § 13-3102): Carrying a concealed deadly weapon without meeting age/permit requirements is a Class 1 misdemeanor, punishable by up to 6 months in jail and a $2,500 fine
• Possession of a weapon on school grounds: Class 1 misdemeanor or felony depending on circumstances
