A 1958 Law Meets a Second Amendment Test
A federal appeals court has struck down the core of the 1958 Federal Switchblade Act. On October 21, 2026, a panel of the 5th Circuit held in Knife Rights, Inc. v. Blanche that the law's ban on interstate manufacture and sale of switchblades violates the Second Amendment. The court found that switchblades are "Arms" protected by the Second Amendment and that the ban on introducing, manufacturing, transporting or distributing them in interstate commerce is unconstitutional.
The decision does not make automatic knives legal everywhere overnight, but it applies the Supreme Court's modern gun-rights test to a federal knife statute, and it reaches a law that has shaped the knife market for almost seven decades.
Where the Switchblade Act Came From
The law dates to 1958, when, by the mid-1950s, popular culture's fixation on the switchblade as a symbol of youth violence helped push public and congressional demand for controls. The legislation, Public Law 85-623, was passed on August 12, 1958. It targets interstate commerce: it regulates the manufacture of switchblades and their introduction into interstate commerce, and it has no application to laws within a state. The definition covers gravity knives and butterfly knives under the same umbrella.
The practical effect was that makers could not ship automatic knives across state lines, which pushed many of them to sell to military or law enforcement buyers, or to sell only within a single state.
The Lawsuit
Knife Rights and co-plaintiffs challenged the interstate-commerce restriction, along with a possession ban on Native American reservations and in U.S. territories, under the Second Amendment. The case was filed in U.S. District Court for the Northern District of Texas and was originally captioned Knife Rights, Inc. v. Garland. The plaintiffs asked for a ruling that the law is unconstitutional and a permanent injunction. The lawsuit did not challenge the existing import ban.
The district court dismissed the case, holding that the Act does not implicate the Second Amendment because it restricts "distribution," not the keeping or bearing of arms, according to an advocacy-group account of the case. The Fifth Circuit's ruling reverses the core of that reasoning.
The Panel and the Reasoning
Judges Elrod, Willett and Wilson issued the decision, which was unanimous. Judge Elrod wrote that the Justice Department failed to point to any historical statute similar to the federal switchblade ban. She compared the law to the regulations in Heller and Bruen that addressed "perceived societal problems," which the Supreme Court rejected as inconsistent with the Second Amendment.
The Bruen Test
Under New York State Rifle & Pistol Association v. Bruen, the Supreme Court held that the Second Amendment includes the right to be armed for self-defense at home and in public, and that a restriction has to be consistent with the nation's historical tradition of firearm regulation. Here the court applied that test to knives. The government's burden was to show an analogous historical regulation, and the panel found it had not.
One group arguing against the Act had said that charges brought under it would face strong challenges under Bruen. The Fifth Circuit's decision tests that argument at the appellate level.
A Partial Win
The ruling is narrower than the headline suggests. The court rejected the plaintiffs' facial challenge, so bans can still apply in places such as courthouses, federal prisons, embassies and military bases. It also found the plaintiffs could not challenge a separate provision covering U.S. territories and tribal land. The case now returns to the Northern District of Texas.
In legal terms, the decision means the interstate ban is unconstitutional as applied to the plaintiffs' conduct, not that every application of the statute is invalid.
What Changes for Knife Owners
For now, little changes on the ground. State knife laws are not affected, and many states have their own restrictions on automatic knives. A federal ruling that removes the interstate commerce ban does not make switchblades legal in a state that prohibits them. The decision applies directly in the Fifth Circuit, which covers Texas, Louisiana and Mississippi, and its force elsewhere depends on how other courts and the government respond.
Interstate Sales
The practical question is whether makers and retailers will start shipping automatics across state lines. Many will wait to see whether the government appeals, whether the ruling is stayed, and how federal agencies respond. A business that guesses wrong risks federal charges in a circuit where the ruling does not apply.
What Comes Next
The government may seek rehearing by the full Fifth Circuit or ask the Supreme Court to review the decision. The district court will also have to apply the ruling on remand. If the decision stands, it could be cited in challenges to other federal and state knife restrictions, and the Bruen-based reasoning gives advocates a template.
Knife Rights has pursued a state-by-state campaign to loosen restrictions on knives, and this decision is a significant federal-level win for that approach. Collectors and everyday carriers should follow the case as it moves, watch for any appeal, and keep complying with state and local laws in the meantime. A ruling on paper is not a defense if you carry in a state that bans the knife.
