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.

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

    1. If you are 21, (as far as I’ve read from multiple websites…) Go nuts! There is no blade length of any kind I’ve ever seen, and I think you can even carry it concealed (if you can manage lol) here’s some links to back it up
      First of all, at the top of this page, the 4th bullet down, say:
      “Knives of any length are legal.” (if you are 21 I believe)

      And here is a link

      Arizona: Anything goes. Tell a cop if you’re carrying one.

  2. 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.

    1. You should be good if you always have part of it showing. Keep in mind that one police officer may be different from another. Be safe and never reach for a knife when talking to a police officer.

  3. Im 16 and just bought a butterfly knife, am I able to carry it on me legally? thanks.

    1. unless you find a butterfly knife that’s 4 inches or under, you have to carry it Unconcealed and in clear view.

  4. I live in Arizona and i’m underage to carry a concealed knife. I want a butterfly knife and I don’t know if I can have it closed in sight on my belt or I have to have it open?

    1. unless you find a butterfly knife that’s 4 inches or under, you have to carry it Unconcealed and in clear view. The definition of a knife under 4 inches legally isn’t a “knife”, its a “knife shaped tool” which is way underaged people can carry it concealed.

  5. Can someone under 21 carry a non pocket knife unconcealed??

  6. Is it illegal for someone under 21 to own a non pocket knife

    1. Yes, all types of knives are legal and considered tools.

  7. I just bought a straight blade overall is 12 inches the blade is 7. So if I have it in the sheath and strapped to my waste I won’t get in trouble?

  8. Im 13 and i bought a karambit at a big five in Arizona they let me with parental consult so is that legal.

    1. It is legal to own and carry, but it is not a pocket knife, so don’t carry it concealed.

  9. As Crockodile Dundee says,”that’s not a knife”,THAT’S A KNIFE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  10. I am 16 and if I have a 12 inch knife and the handle is under my shirt is that legal

    1. The HANDLE under your shirt? so the sharp part is sticking up? I think (hope) I’m confused… As long as the knife is displayed since you are under 21 and the knife is larger than 4 inches (I believe that’s the cutoff, it’s either 3.5 or 4 inches). Your best bet is display it in a carrying case that clips on your belt, or anywhere visible… If you mean the handle is covered by your shirt but the blade sticks out down past that, I would guess that’s considered visible but that may be a gray area. My advice: ask a lawyer or (easier solution) get a sheath for it.

    2. Typically concealed means if it is covered at all. So a weapon (knife) partially covered by your shirt could be construed as concealed. To be safe make sure the entire knife is visible. – In a sheath that is designed to protect the blade should be fine, so long as the sheath is not designed to conceal the blade to appear as something other than a knife.

  11. I am 14 and I own a 3.5 in pocket knife can I carry it concealed?

    1. Yes. The limit is either 4 inches or 3.5 ( I think I’ve read both) but either way its legally not considered a knife, it’s technically a “knife shaped tool” in AZ so you should be perfectly fine, just make sure you tell and officer, especially if he’s about to search you.

  12. Is a sword the same as a knife I now they are both blades but we’ll on is usually not more than 9″ the other is about 4′

  13. And what about a bayonet now that there is not concealed handgun license requirements
