U.S. Automatic Knife Laws
(This report updated May 23, 2019 is believed to be current.)

The laws for automatic knives are always changing and to some degree very confusing about purchasing, selling, possessing and transporting. The Switchblade Act of 1959 has been amended over the years and in 2009 President Obama amended it to allow spring assisted knives and other one hand opening knives are allowed to be sold and distributed. Here is a list of states and their automatic knife laws categorized by possession and carryNote these laws change frequently and most of them have caveats so always check your local laws before purchasing any automatic knives.
