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.
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.
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.
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.
