The Law in Detail
Key statutes: Ariz. Rev. Stat. §§13-3101, 13-3102, 13-3120
Arizona is one of the most permissive knife states: anyone 21 or older may carry any knife openly or concealed, and §13-3120 preempts all local knife ordinances. For those under 21, concealed carry of a non-pocketknife deadly weapon is a Class 3 misdemeanor, rising to a Class 1 misdemeanor (up to six months and $2,500) for failing to accurately answer a peace officer about it. Deadly weapons remain banned at polling places on election day and on school grounds, with no pocketknife exception at the polls.
