ARS 13-3120 regulates knives in the State of Arizona and expressly prohibits local governments
from regulating, among other things, their possession, transport or use. "Knife" means a cutting
instrument and includes a sharpened or pointed blade.
Under ARS 13-3101, a "deadly weapon" means anything that is designed for lethal use. The
term certainly includes a firearm, but does not specifically include knives. Knives are generally
regarded as tools. However, knife carriers must obey laws that governing concealed weapons
or that prohibit them from certain places (including courtrooms and other government buildings)
A pocket knife is a folding knife with a blade less than 4 inches in length. It is not considered a
deadly weapon under ARS 13-3102 and a citizen of any age may lawfully carry a pocket knife
concealed on his or her person, within his or her immediate control in or on a means of
transportation. However, even pocket knife carriers may be required to obey the laws that
govern concealed weapons or that prohibit them from certain places (including courtrooms and
other government buildings).
