Pocket knives are generally legal to own and carry in Minnesota, with no state-level blade length limits for folding knives used as tools. The primary restriction targets switchblades under Minnesota Statute § 609.66, while intent and location heavily influence legality.
Defining Pocket Knives
Pocket knives typically refer to compact folding knives designed for everyday tasks like cutting packages, preparing food, or outdoor use. In Minnesota, these qualify as legal tools unless modified or used threateningly. They differ from fixed-blade knives, which also face few restrictions beyond context.
Key Minnesota Statutes
Minnesota Statute § 609.66 prohibits manufacturing, transferring, or possessing switchblade knives that open automatically by button, spring, or gravity without manual force.
Ordinary pocket knives avoid this ban, as § 609.02 defines “dangerous weapons” by design or intended unlawful use, not mere possession. Penalties range from misdemeanor (up to 90 days jail, $1,000 fine) to gross misdemeanor or felony in school zones.
Carry Rules
Open carry of pocket knives is legal statewide for legitimate purposes like work, camping, or fishing. Concealed carry follows the same rules unless the knife qualifies as a dangerous weapon through threatening display. No blade length cap exists, allowing 2-inch or longer folders. Spring-assisted models occupy a gray area but are typically permitted if manual initiation is required.
Prohibited Locations
Knives are banned on school property (§ 609.66 subd. 1d), courthouses, government buildings, and certain secured areas. Exceptions apply to peace officers, permitted carriers, or supervised events. Local ordinances in cities like Minneapolis may add rules, so check municipal codes.
Exceptions and Challenges
Military, law enforcement, and collectors (for exhibition) have narrow exemptions. A 2024 federal lawsuit by Knife Rights challenges the switchblade ban as unconstitutional, potentially legalizing them soon. Blades like balisongs or gravity knives remain legal absent automatic opening.
Practical Advice
Carry for clear purposes like EDC or recreation to demonstrate non-weapon intent. In vehicles, no special rules apply beyond prohibitions. Consult local laws for urban areas and avoid brandishing to prevent assault charges.
