Arizona offers some of the most permissive knife laws in the U.S., allowing adults broad rights to own and carry various types without blade length limits or permits.
Statewide Permissions
Adults 21 and older can openly or concealed carry any knife—including switchblades, butterfly knives, fixed blades, daggers, bowies, and automatics—per ARS § 13-3120, which preempts stricter local rules. No statewide bans exist on types or sizes; knives are treated as tools unless used criminally.
Age Restrictions
Minors under 21 may carry folding pocket knives openly or concealed but face limits on “deadly weapons” like fixed blades or automatics. Prohibited entirely for those under 18 in certain contexts.
Prohibited Locations
Knives are banned in schools, polling places on election day, government buildings, correctional facilities, and nuclear/hydroelectric plants. Open carry in vehicles is fine if not for unlawful purposes.
Carry Methods
Constitutional carry (no permit needed) applies statewide since 2010 reforms. Disclose concealed deadly weapons to police if asked, though basic pocket knives often exempt.
Legal vs. Illegal Knives
Penalties for misuse (e.g., brandishing) range from misdemeanors to felonies based on intent. No 2026 changes reported—carry responsibly.
