Understanding the Legal Landscape of Pocket Knives in Arizona

Arizona has some of the most lenient knife laws in the United States, offering significant freedom for knife owners and enthusiasts. The state’s regulations are designed to be straightforward and permissive, with few restrictions on the purchase, ownership, and carrying of knives.

Knife Definition and Classification

In Arizona, a knife is legally defined as a cutting instrument with a sharpened or pointed blade. Knives are generally considered tools rather than weapons under Arizona law, unless they are used or intended to be used in a dangerous manner.

Carrying Regulations

Arizona’s knife-carrying laws are notably permissive:

Open Carry: All types of knives can be openly carried without restrictions.
Concealed Carry: Individuals aged 21 and over can carry any type of knife concealed.
Pocket Knives: Any folding knife with a blade less than 4 inches in length is considered a pocket knife and can be carried by persons of any age, either openly or concealed.

Legal Types of Knives

Arizona law does not prohibit any specific types of knives. The following are all legal to own and carry:

Pocket knives
Fixed-blade knives
Balisong (butterfly) knives
Switchblades
Bowie knives
Gravity knives
Automatic and assisted-opening knives

There are no restrictions on blade length or the number of edges a knife may have.

Age Restrictions

Individuals 21 and older can carry any type of knife, either openly or concealed.
Those under 21 can carry pocket knives (blade length under 4 inches) but are restricted from carrying larger knives concealed5.

Location Restrictions

While Arizona law is generally permissive, there are some location-based restrictions:

Knives are prohibited on school grounds, in government buildings, and in secured areas of airports.
Private businesses and venues may prohibit knives on their premises.

Legal Considerations

Arizona law (A.R.S. 13-3120) prevents local governments from enacting their own knife regulations, ensuring consistency across the state.
Knives are not automatically classified as deadly weapons, but can become so if used with criminal intent.
