Arizona Knife Laws
Arizona is one of the simplest states in the country for knives. There is no blade length limit, no prohibited knife type, and full statewide preemption, so no Arizona city can add a rule of its own. If you are 21 or over you may carry concealed without restriction.
This is not legal advice, and we are not lawyers. It is a plain reading of published summaries and the statutes they cite, kept current on a fixed schedule. Local ordinances are frequently stricter than state law and are not all captured here. Check the statute, and check your city, before you carry.

How fresh this is, and how you can tell
Two dates sit above, and they are not the same thing. Checked by us is the last time a person went back to the sources and confirmed this page still matches them. Source last revised is when the American Knife and Tool Institute last updated its own Arizona page. A 2021 revision date is not automatically wrong — it usually means nothing has changed since — but it does mean nobody had looked recently, and that is exactly the gap this page exists to close.
Crossing the Arizona state line
Knife law stops at the border and the next state does not have to agree with this one. If you drive, these are the states you are most likely to carry into, and what changes when you do.
| State | Automatic knives | Concealed blade limit |
|---|---|---|
| California | Legal with conditions | No single blade length governs. It is unlawful to carry a dirk or dagger concealed on the person; a folding knife that is closed, or one without a locking blade, is treated differently. |
| Nevada | Legal | No blade length governs statewide, except that a machete may not be carried concealed. The county rule is the one that catches visitors. |
| Utah | Legal | No blade length governs and concealment is not an issue. |
| New Mexico | Restricted or banned | Concealed carry of a deadly weapon is barred outright, and a knife that can cause death or great bodily harm counts. No blade length governs. The exceptions are your own home or land, a private vehicle, and a state concealed handgun license. |
A knife that is lawful in your pocket at home can be unlawful the moment you cross, and nobody stops you at the line to tell you. The map for all fifty states covers the rest.
Common questions about Arizona knife laws
What size knife is legal to carry in Arizona?
No blade length limit. Adults 21 and over may carry a concealed knife without restriction; under 21 it is pocketknives only.
Are switchblades legal in Arizona?
Never restricted.
Which knives are banned outright in Arizona?
None.
Does Arizona have knife preemption?
Yes. Arizona has statewide preemption, which means a city cannot write its own stricter knife ordinance. One rule covers the whole state, and that is most of what preemption is worth.
Can I keep a knife in my car in Arizona?
Where a state has a concealed carry limit, a knife in a glovebox or a door pocket is generally treated as concealed. Read the concealed line above and apply it to the vehicle. If that line says concealment is not the issue in this state, the vehicle is not the issue either — but where you drive to still is, because schools and courthouses are barred everywhere.
Where this comes from
Two independent sources, cross-checked against each other, and the statute text where they disagree. The automatic knife column is the American Knife and Tool Institute’s state automatics table, checked against Knife Rights’ own switchblade legality table and their legislative update log. Everything on a state page is quoted or closely tracked from that state’s AKTI page, and we print the date AKTI last revised it so you can see for yourself how fresh the underlying work is.
Where a source is older than a change we know about, we say so on the page rather than quietly leaving the old answer up. That is the whole reason this is checked every two months.
