Arizona Knife Laws

If you live in Arizona you are in luck, Arizona has the best knife laws of all 50 states. Basically, you can own any type of blade you want and carry it concealed or in the open without worry. There are no municipal laws so you won’t have to worry about cops the next town over harassing you for something that is legal in your home town.

What is Legal/Illegal in Arizona

  • Pocket knives are legal.
  • Balisong knives are legal.
  • Switchblades, gravity knives, Bowie knives, and stilettos are legal.
  • Knives of any length are legal.
  • It is legal for anyone over 21 to carry knives concealed.
  • It is illegal to not inform a police officer when they stop you that you are carrying a concealed knife when the knife is not a pocket knife.
  • It is illegal for someone under 21 years of age to carry a non-pocket knife concealed.
  • It is illegal to bring a knife into schools.

Outside of what is listed above, it is illegal to use a knife to commit a behavior that is already illegal. What this means is that it is illegal to rob a bank with a knife and you will be penalized more severely than if you robbed a bank without a weapon. You can read the law here.

Removal of Municipal Knife Laws in 2011

In the old days, the State of Arizona had its own knife laws and individual cities would have their own knife laws as well. The result was that people were being charged with having illegal knives that are 100% legal in their home town.

In 2011 the State of Arizona preempted all municipal laws and, basically, made every type of knife legal. The new code was based off of the fact that the majority of knife owners used their knives as tools rather than weapons. The old laws were harming innocent citizens instead of criminals and were finally changed.

Conclusion on Arizona Knife Laws

If you are from Arizona, go buy Balisongs, gravity knives, Bowies, stilettos, and whatever else you want: you live in the coolest state in America. Just don’t use it for a crime.

I am not an attorney so take this article with a grain of salt. I am just a law student. Also, this is not legal advice, talk to an attorney if you want that.

    I have a ‘short machete’ with a 10′ blade which I have used when either camping or hunting. What’s the difference between a large knife and a ‘short machete’? Is a machete, which is a basic tool, regarded the same as a large knife by authorites?

  4. Airborne 71 says:

    I live in Arizona and did not know the law here ,and had not been carrying one for that reason, Thanks for the good info. I own a “Neck Lance” knife as well its meant to be worn around the neck and can be easly concealed .

  5. Glenn Jacobs says:

    Way many years ago I bought a ton of government surplus parachute harness. Behold, a paratrooper’s switchblade knife.

    In those days, I believed what I saw on TV, and that it was a felony to possess such a terrible weapon.

    I was terrified I would be sent up the river, so I called the police to come and take it away.

    The kindly “Mayberry” type police officer informed me that switchblade knives were legal in Arizona even then.

  6. Brian_W204 says:

    Couple of typos above you should correct:

    “it is illegal to use a knife to commit a behavior that is already legal” should be “it is illegal to use a knife to commit a behavior that is already illegal”

    “made every time of knife legal” should be “made every type of knife legal”

  7. ddog says:

    so im 16 and live in az, so can I carry a 3.5inch pocket knife with me?..thanks to whoever answers this I just cant seem to find answers anywhere else

  8. Keith says:

    Sounds like New Hampshire knife laws except New Hampshire doesn’t call you a child until you reach the age of 21. Maybe someday AZ will catch up to NH with sane, rational knife laws ;)

  9. Echo Sierra says:

    Your average multitool carries a hefty blade. A tool kit in your pocket. And if you’re worried about self-defense against an atracker with a knife, I’ve never seen anyone stopped for packing a large crescent wrench.

  10. Ray N says:

    I took an 8 day self course. You do not want to be in a knife fight, but better to have one than not. We had an exercise using magic markers and could only “cut” with the tip most everyone cut themselves at least once. Even some one well train will most likely be injured.
    see 21 foot rule read both parts:

  11. ipscshooter says:

    I don’t believe this statement is correct.

    “•It is illegal to not inform a police officer when they stop you that you are carrying a concealed knife when the knife is not a pocket knife.”

    I believe that is only illegal if an officer asks if you have deadly weapon and fail to accurately inform.

    From A.R.R. 13-3102

    “(b) When contacted by a law enforcement officer and failing to accurately answer the officer if the officer asks whether the person is carrying a concealed deadly weapon;”

  12. Kelsey says:

    I have wondered if you could carry them in public now I know… The most thing I wondered about was the age you have to be to buy a machete. Yes I’m only 13 and a girl but I used my friend’s machete to go through the woods and make paths. I’m also terrified of snakes and we have a bunch of them and one time I didn’t have the machete and I almost got bit. Even though I’m a girl it doesn’t mean I don’t have a right to own a machete…What age do you have to be to purchase a machete?

  13. JEFF SUN says:

    SO, WE CAN MANUFACTURE, TRADE, USE AND OWN POCKET KNIFE, SWITCHBLADE KNIFE, OUT-TO-THE-FRONT STILETTO KNIFE.
    IF OK, WE WILL SET UP A COMPANY DOING THIS BUSINESS.
    ANYONE CAN MAKE SURE IT IS OK?

  14. larry says:

    I was wondering if it is illegal to carry a 27 inch sword in Arizona

  15. austin says:

    What about carrying swords and such. What are the laws on that.

  16. Ben says:

    I have a quick question. I’m 15 and I own a knife with a blade just over 2 and half inchs. A: Can I carry it? B: It has a clip so it hangs in my pocket and you can see the clip when its in my pocket, would that be considered a ‘concealed weapon’? Thank you.
