A Fifth Circuit panel of three judges found Section 1242 of the Federal Switchblade Act unconstitutional under the Second Amendment, ending its enforcement. The case Knife Rights, Inc. v. Blanche struck down interstate curbs on making, shipping, and selling automatically opening knives after the government failed the Bruen historical-tradition test.

Concealed-carry statutes from earlier eras did not justify blocking production or commerce, and the court treated switchblades as ordinary self-defense arms rather than unusual weapons. Knife Rights linked the 1958 statute to public panic over juvenile crime and said the win is incomplete because the matter returns to district court, remains unimplemented, and may face Justice Department review. The NRA Institute for Legislative Action observed that constitutional protection extends to knives and, as a New York court recently held, body armor.
