AZ Knife Laws [Knife Laws in Arizona]

Educating yourself about your state’s knife laws is essential, especially if you frequently need to walk around with a knife in the streets.

Each state has different laws regarding the open and concealed carry of knives and switchblades.

We’ve summed up the state’s knife laws right here in this guide for those who live in Arizona. So, let’s have a look!

What Defines a Knife in Arizona?

Under Arizona’s state law, a knife is any tool with a sharp or pointed blade and can be used for cutting. In addition, a knife can be used as a weapon. However, this definition differs from deadly weapons, which are specifically designed to kill. These include firearms and swords.

In other words, a knife in Arizona isn’t a weapon unless somebody commits a crime with it.

Citizens and residents in Arizona can legally use knives as a tool for cutting, fishing, hunting, and repairing.

What Knives Can Citizens Carry in Arizona?

Under Arizona’s knife laws, all citizens can carry pocket knives in public without any restrictions or prohibitions. However, the person must be over the age of 21. Other than that, the knife’s blade must be shorter than four inches, and it must be carried in a concealed manner.

Adults over 21 may carry the knives concealed or openly, and there aren’t any restrictions, except in schools and around polling locations. Hydroelectric and nuclear power generating facilities are also included in this.

Nevertheless, all citizens are required to confirm that they’re carrying a knife in case a police officer inquires about that.

Here’s a clearer disclosure about the type of knives allowed in Arizona:

  • Pocket knife
  • Dagger
  • Switchblade
  • Bowie knife
  • Machete
  • Ballistic knife
  • Gravity knife
  • Stiletto
  • Butterfly knife

And now, let’s check some of the different knives’ laws.

Fixed Blade Knife Laws in Arizona

Similar to other types of knives, you can legally carry a fixed blade knife in Arizona, but only if you’re an adult (over 21). 

Butterfly Knife Laws in Arizona

Butterfly knives aren’t viewed as pocket knives under Arizona’s knife laws. In other words, you can only carry a butterfly knife if you’re over the age of 21.

Arizona’s Automatic Knife Laws

Arizona is one of the few U.S states that allow buying, selling, using, and carrying (open or concealed) automatic knives. However, citizens under the age of 21 are restricted from carrying automatic knives in public.

Can Felons Carry Knives in Arizona?

If someone is convicted of a crime, they’re required not to carry any deadly weapons in public. However, knives, especially switchblades and hunting knives, qualify as weapons, meaning that a felon can’t carry one in public.

What Is a Prohibited Possessor?

Prohibited possessors aren’t allowed to use or carry deadly weapons to prevent legal penalties and jail time. Based on Arizona’s legislation, a “prohibited possessor” is anyone who is:

  • A danger to self or other people
  • Serving a probation term at the time of possession
  • Serving time in a correctional center at the time of possession
  • Convicted of an adjudicated delinquent or a felony
  • Waiting to get their civil right to carry a firearm
  • Traveling for any purpose in Arizona (for non-immigrant or undocumented travelers)
  • Not eligible for criminal procedure laws of Arizona (rule 11)

One of the primary goals behind Arizona’s state knife laws is to eliminate the contradiction of local municipalities’ ordinances and make everything clear for citizens regarding the use and carry of knives.

In 2013, the State legislation was issued to supersede local laws to make them easier to understand for citizens and residents of Arizona.

Pre-2011 Arizona Knife Laws

Before 2011, Arizona had its own knife laws, and they could vary from one city to another. As a result, innocent citizens would be fined for carrying tool knives without doing anything wrong, which was just unfair.

Luckily, the laws were revised in 2011, ensuring that all types of knives are legal. The argument behind the rule is that almost all citizens use their knives peacefully, so it didn’t make sense to ban knives altogether.

What Self-Defense Weapons Are Legal in Arizona

Along with knives, here are some other self-defense weapons that you can legally carry in Arizona:

  • Tasers
  • Pepper sprays
  • Stun guns
  • Knuckles

Knife Trading in Arizona

Buying and selling knives in Arizona is legal, as long as the knife isn’t being sold to a prohibited person or someone under the age of 21.


If it was found that someone under the age of 21 is carrying a knife with a blade longer than four inches, they’d be fined $500. They’d else get up to 30 days of confinement.

On the other hand, answering inaccurately about possessing a deadly weapon would result in a $2,500 fine and up to six months of jail time.

Final Words

Alright, by now, you should be fully aware of AZ knife laws. If you’re over the age of 21, there’s nothing you need to worry about.

However, if you’re under 21, you may only carry the knife in a concealed manner. Plus, its blade shouldn’t be longer than four inches.
