Butterfly Knife laws in Arizona

The possession, ownership, and sale of butterfly knives (also known as balisongs) are generally legal throughout Arizona. Arizona law does not specifically prohibit butterfly knives as a class of weapon, nor do they fall under the state's prohibitions against switchblade knives, which are defined by a spring or mechanical device to open. Therefore, carrying a butterfly knife openly or concealed is not inherently illegal under state statute, though local ordinances or specific circumstances, such as carry in a prohibited place, could create restrictions. While state law permits their possession and carrying, travelers should be aware that the Transportation Security Administration (TSA) prohibits butterfly knives in carry-on luggage on aircraft. For residents, while state law is permissive, it is advisable to verify if any specific municipalities within Arizona have enacted local ordinances that may restrict the possession or carrying of butterfly knives. Age requirements for purchasing any knives, including butterfly knives, typically apply, aligning with general retail regulations for potentially dangerous items. Arizona law does not currently classify butterfly knives as unlawful weapons, nor does it impose specific penalties for their possession, sale, or transport outside of federal regulations for air travel or potential local restrictions. However, the general laws concerning dangerous weapons and prohibited places of carry, such as schools or courthouses, would still apply if a butterfly knife were used in a manner that constituted a threat or was carried into a constitutionally or statutorily restricted area. Travelers are strongly advised to check their butterfly knives as baggage when flying and to be aware of any local regulations that may supplement or differ from state law.
