The Fifth Circuit ruled October 21 that the Federal Switchblade Act's interstate-commerce restriction violates the Second Amendment, reversing dismissal of that part of a challenge brought by Knife Rights and individual and business plaintiffs. The decision in Knife Rights v. Blanche did not invalidate every provision at issue: the court left dismissal of a separate challenge to restrictions in specified federal jurisdictions intact and returned the case for further proceedings.
Chief Judge Jennifer Walker Elrod wrote the opinion for a panel that also included Judges Don Willett and Cory Wilson. The lawsuit began in September 2024 in the Northern District of Texas. It sought declaratory and injunctive relief against two provisions, 15 U.S.C. §§ 1242 and 1243. Section 1242 regulates the interstate supply chain; section 1243 reaches manufacture, sale and possession in particular places.
Section 1242 prohibits knowingly introducing switchblade knives into interstate commerce, manufacturing them for that introduction, or transporting or distributing them in interstate commerce. The plaintiffs include two federally licensed firearm dealers that said the law prevented them from marketing automatic-opening knives. Individual plaintiffs described intended purchases, interstate travel and uses ranging from self-defense to hunting and fishing. Their claims concern access to knives, not simply permission to keep an already-owned knife at home.

Acquisition is part of the protected conduct
The panel found that switchblade knives qualify as arms protected by the Second Amendment. It cited their defensive uses, their historical development and a record showing millions of automatic-opening knives in the United States. It also identified lawful utility and outdoor uses. The court rejected the government's argument that the knives were not in common use, rather than treating their association with criminal activity as sufficient to place them outside constitutional protection.
The next question was whether the right to keep and bear arms reaches the transactions needed to obtain them. The panel concluded that it does. Although the amendment does not expressly use words such as purchase or sale, the court reasoned that possession requires a corresponding ability to acquire arms. It extended that reasoning to manufacture, transportation and distribution. For the dealer plaintiffs, that made the supply-chain restriction subject to constitutional analysis rather than exempt from it because some intrastate sales remained possible.
The district court had focused on whether the federal restriction amounted to an effective ban on possession. The appellate panel said that approach failed to apply the required Bruen analysis. Once protected conduct was implicated, the government had to justify the restriction through the nation's historical regulatory tradition. The question was not merely whether a knife could still be obtained somewhere, but whether this particular restriction matched the principles reflected in historical arms laws.
The government's historical evidence largely concerned restrictions on carrying concealed weapons. The panel distinguished those rules from restrictions on manufacturing, transporting and distributing them. Of nearly 200 pre-1900 statutes cataloged in an article cited by the government, the court identified only two that regulated bladed weapons in an analogous manner. It treated those as outliers, not a representative tradition. The court did not need to resolve whether the government's stated purpose was historically supportable because the manner of regulation failed its analysis.
A separate possession restriction survives this challenge
Section 1243 produced a different outcome. It covers manufacture, sale or possession within U.S. territories or possessions, Indian country, and the special maritime and territorial jurisdiction of the United States. The panel found standing to challenge that provision, disagreeing with the district court on that threshold issue. But standing only allowed the plaintiffs to bring the claim; it did not establish that the law was unconstitutional.
The plaintiffs pursued a facial challenge and therefore had to establish that the provision had no constitutional applications. The government pointed to locations including courthouses, federal prisons and military bases. The panel emphasized Supreme Court recognition of restrictions in government buildings, including courthouses, and concluded that the plaintiffs had not met their burden. It affirmed dismissal on that basis, without deciding that every application of § 1243 is constitutional.
The opinion's operative direction is a remand to the Northern District of Texas, not a retail availability announcement or a blanket authorization to possess switchblades wherever federal law applies. Further proceedings must implement the ruling on § 1242. The opinion does not specify the final injunction's terms or a date on which dealers should change their practices; those details remain to be established through the subsequent court proceedings.
