Michigan knife laws favor responsible ownership and open carry for most blades, with strict limits on concealed carry of certain types. Key statutes MCL 750.226 and 750.227 prohibit dangerous weapons carried with unlawful intent or concealed, treating violations as felonies.
Ownership Rights
Adults 18+ can own nearly all knives, including switchblades legalized in 2017 via Public Act 96 repeal of MCL 750.226a. No blade length limits exist statewide for possession; fixed blades, folders, and autos are fine at home or on private property.
Minors face restrictions, and schools ban all knives under MCL 750.237a without authorization.
Open Carry Rules
Open carry is legal statewide for pocketknives, fixed blades, and autos absent unlawful intent. MCL 750.226 only criminalizes arming with daggers, dirks, stilettos, or blades over 3 inches if meant to harm—no general ban applies.
Private property, courts, and schools override this; always get permission.
Concealed Carry Limits
Concealed carry risks felony charges for daggers, dirks, stilettos, double-edged non-folding stabbers (MCL 750.227). Pocketknives under 3 inches avoid presumption of intent; longer blades or fixed types need caution.
Vehicle storage counts as concealed unless in trunk/out of reach—same rules apply.
Prohibited Types
Double-edged fixed blades draw heaviest scrutiny as “stabbing instruments,” banned concealed or in vehicles. Ballistic knives remain illegal federally, but Michigan focuses on intent over type.
Local ordinances in Detroit and Lansing cap public blades at 3 inches—check city codes, as no preemption exists.
Penalties and Defenses
Felonies under MCL 750.226/227 carry up to 5 years prison and $2,500 fines. Defenses include lawful purpose (hunting, work), dwelling/business exceptions, or lack of intent—document use.
Practical Tips
Carry openly or pocket folders visibly. For EDC, opt for single-edge <3″ blades. Verify locals via municipal sites; apps like Knife Rights aid compliance.

Stay legal by prioritizing intent and visibility—consult attorneys for edge cases.
