Many states have preemption laws barring local knife restrictions (cities like NYC, Chicago, and DC are notable exceptions). The federal Switchblade Knife Act (15 USC §1241) restricts interstate commerce in switchblades but does not apply to intrastate sale or possession. Federal property and TSA-controlled areas have separate restrictions.
