There are no restrictions on blade length or number of edges for knives in Arizona.
Carrying Laws
Open Carry
- Open carry of any knife is legal for all ages
Concealed Carry
- Individuals 21 and older can concealed carry any knife

- Nuclear/hydroelectric facilities
- Private property that prohibits weapons
Age Restrictions

State Preemption
Arizona has knife law preemption, meaning local jurisdictions cannot enact stricter knife regulations than state law.
