Yes, Michigan law permits butterfly knives (balisongs) for possession and carry, provided they meet state blade length limits. Local ordinances in cities like Detroit or Grand Rapids may impose additional restrictions, so compliance with municipal codes is essential.
Key Regulations for Butterfly Knives (Balisongs) in Michigan
- Blade Length Limit: Legal balisongs must have blades under 3 inches. Knives exceeding this are classified as dangerous weapons under MCL 750.226a.
- Open Carry Restrictions: While possession is legal, openly carrying a balisong in public may violate local disorderly conduct ordinances or Michigan’s concealed weapon laws if deemed “dangerous.”
- School Zones & Government Property: Federal and state laws prohibit balisongs on school grounds or in courthouses, regardless of blade length.
Michigan’s 2026 legislative session may introduce stricter regulations, as proposed bills aim to reclassify balisongs as “switchblades,” potentially aligning with federal restrictions. Monitor updates from the Michigan State Police (MSP) and local law enforcement for enforcement shifts.
