Arizona Knife Law Snapshot
Short version: Arizona is one of the more permissive states for everyday knife carry, but concealed carry, age, sensitive locations, and police contact still deserve attention.
Common pocket knives are the lowest-risk category for everyday carry.
No broad state-level open-carry ban appears in the cited Arizona sections.
21+ and under-21 carry are treated differently.
Schools, polling places, public events, and public establishments need extra care.
Can You Carry a Knife in Arizona?
| Situation | Plain-English summary | Status | Source |
|---|---|---|---|
| Common pocket knife | Usually the safest EDC category. Arizona's misconduct statute repeatedly separates pocket knives from broader concealed deadly weapon rules. | Generally allowed | § 13-3102 |
| Open carry | For ordinary knives, Arizona does not show a broad state-level open-carry ban in the cited sections. Location and intent still matter. | Generally allowed | § 13-3102 |
| Concealed carry, age 21+ | Adults 21 and older are not covered by Arizona's under-21 concealed deadly weapon restriction. Arizona is commonly described as a permitless or constitutional-carry state, but you still must avoid felony/violent-crime contexts and answer accurately if law enforcement asks about a concealed deadly weapon. | Allowed with duties | § 13-3102(A)(1) |
| Concealed carry, under 21 | People under 21 may conceal a pocket knife, but concealing other deadly weapons can create a misdemeanor risk. Carrying openly is generally the lower-risk route for non-pocket knives. | Pocket knife only | § 13-3102(A)(2) |
| Blade length | No general statewide blade-length limit for ordinary knives appears in the cited Arizona sections. | No general limit found | § 13-3101, § 13-3102 |
| Local city or county knife rules | Arizona has knife-specific state preemption. Local knife rules that are inconsistent with or more restrictive than state law are generally void, subject to the statute's exceptions. | State preemption | § 13-3120 |
Concealed Carry Details
This is the section most EDC users should read carefully. Arizona's pocket knife exception and under-21 rule are both important.
Concealed carry is broader for adults
Arizona's current misconduct statute targets concealed deadly weapon carry in specific contexts and has a separate under-21 restriction. For adults 21+, CJRB found no general concealed-knife permit requirement in the cited current statute. This is the framework many third-party summaries describe as constitutional carry.

Pocket knife exception matters
For people under 21, Arizona makes it misconduct to carry a concealed deadly weapon, except a pocket knife, on the person or within immediate control in a vehicle. This is the detail many summaries flatten too much.

Answer accurately if asked
If a law enforcement officer lawfully contacts you and asks whether you are carrying a concealed deadly weapon, failing to answer accurately can itself create a misconduct issue.

Knife Type Notes
Use this as a carry-risk overview, then check the source links before making a travel or concealed-carry decision.
| Knife type | Arizona summary | Carry risk |
|---|---|---|
| Pocket knives | Best fit for low-friction EDC. The pocket knife exception is important in concealed-carry wording. | Low |
| Folding knives | Generally low risk when carried responsibly, but the statute uses "pocket knife" language, so do not stretch the term too far. | Low to medium |
| Fixed blades | More sensitive for concealed carry, intent, and perception. Open carry is usually clearer than concealment, especially for younger carriers. | Medium |
| Automatic knives, switchblades, OTF knives | Arizona's cited prohibited-weapon definition does not specifically list these knife types. Carry method, age, location, and intent still matter. | Medium |
| Balisongs / butterfly knives | Not specifically listed in the cited prohibited-weapon definition. Treat public carry as higher attention than a simple pocket knife. | Medium |

Places to Be Careful
Even when a knife is legal to own or carry generally, specific places can change the answer.
-
01Public establishments and public events: If an operator or sponsor reasonably requests removal and secure storage, ignoring that request can create a misconduct issue. Source: § 13-3102(A)(10) and § 13-3102.01.
-
02Polling places: Carrying a deadly weapon into an election polling place on election day is a high-risk situation. Source: § 13-3102(A)(11).
-
03School grounds: Do not assume EDC carry rules apply on school grounds. Source: § 13-3102(A)(12).
-
04Nuclear or hydroelectric generating stations: Arizona specifically flags these locations. Source: § 13-3102(A)(13).
-
05Airports, courts, federal property, employers, and private property: These may be controlled by separate federal, facility, workplace, event, or owner rules.
Arizona Preemption
Arizona has knife-specific state preemption. Cities, counties, towns, and other political subdivisions generally may not create knife rules covering transportation, possession, carrying, sale, transfer, purchase, gift, licensing, registration, or use when those rules are inconsistent with or more restrictive than state law.
The statute has exceptions for certain state-law implementation, taxes, and government employees or contractors acting within their work. That means preemption is useful, but it is not a pass to ignore schools, events, employers, private property, federal property, or restricted facilities.
