Pocket knives are generally legal to own and carry in Minnesota, with the state imposing few restrictions beyond a ban on switchblades. Minnesota law focuses on intent and specific prohibited items rather than broad blade length limits or common folding knives.
Key Statute Explained
Minnesota Statute § 609.66 governs dangerous weapons, explicitly prohibiting the manufacture, transfer, or possession of switchblade knives that open automatically. Other knives, including pocket knives, folding knives, and fixed blades, face no statewide ban under this law.
A knife becomes illegal only if possessed “for the purpose of being used unlawfully as a weapon against another,” shifting focus to the user’s intent rather than the tool itself.
Allowed Knife Types
Common pocket knives with manual folding blades are fully legal for everyday carry, outdoor use, or self-defense without unlawful purpose. Hunting knives, utility blades, balisongs (butterfly knives), and Bowie knives also qualify as permissible, as Minnesota sets no blade length restrictions at the state level. Open carry remains straightforward for these items, though brandishing in a threatening way can lead to charges.
Prohibited Items
Switchblades stand out as the sole knife type named in the statute, classified as a misdemeanor with penalties up to 90 days in jail and a $1,000 fine—or a gross misdemeanor (up to 364 days and $3,000) in school, park, or public housing zones. Automatic out-the-front (OTF) knives may fall under similar scrutiny if they open automatically, though the law targets switchblades specifically.
Restricted Locations
Knives qualify as “dangerous weapons” under § 609.02, subd. 6, banning possession on school property (a felony punishable by up to 5 years), in courthouses, Capitol area state buildings, or correctional facilities. Exceptions exist for peace officers, permitted carriers in vehicles, and authorized displays. Local city ordinances may add rules, so check municipal codes for variations.
Carry Rules and Penalties
Both open and concealed carry of legal pocket knives work statewide if not for unlawful intent, supporting activities like camping, fishing, or work. Violations of § 609.66 typically result in misdemeanors, escalating based on location or circumstances. An older “peace bond” statute (§ 625.16) allows courts to require bonds for carrying “offensive and dangerous weapons” without cause for fear of assault.
Practical Advice
Carry responsibly by avoiding restricted areas and ensuring lawful purpose to steer clear of intent-based charges. For collectors or frequent carriers, consult local rules, as Minnesota’s permissive stance rewards caution.
