This bill, known as the Knife Owners' Protection Act of 2025, aims to protect the right of law-abiding citizens to engage in the interstate transportation of knives . It preempts conflicting State and local laws, allowing individuals to transport knives between locations where possession is lawful, provided they adhere to specific federal requirements. These requirements include securing knives in a locked container, locked glove compartment, or locked console when transported by motor vehicle, or in a locked container not in the passenger cabin for air travel. The legislation makes an exception for emergency escape knives with blunt or guarded blades, permitting them in vehicle passenger compartments unless on an aircraft subject to TSA screening. It also clarifies that knives may be kept accessible in temporary lodging during an interstate journey. Individuals complying with these provisions cannot be arrested or detained for state or local knife possession laws, and they can assert this section as a claim or defense in legal proceedings, with the burden of proof shifting to the state in criminal cases. Furthermore, the bill establishes a right of action for individuals whose rights are violated and mandates the award of attorney's fees to prevailing parties.
