Pocket knives are largely legal in Michigan for adults, with no state blade length limits for folding types. Restrictions target concealed carry of certain dangerous knives, and local rules still apply without preemption as of 2026.
Allowed Knives
Folding pocketknives face no statewide restrictions on blade length or open carry. Automatic knives (switchblades) have been legal since 2017 repeal of MCL 750.226a.
Open carry of most knives is permitted, including autos and balisongs. Everyday carry (EDC) folders remain unrestricted statewide.
Restricted Types
Concealed carry or vehicle possession of daggers, dirks, stilettos, and double-edged non-folding knives is prohibited under MCL 750.227(1). Blades over 3 inches presume unlawful intent if carried concealed under MCL 750.226.
Schools ban weapons per MCL 750.237a. No changes in 2026; a proposed bill for shorter double-edged knives remains pending.
Carry Rules
Local ordinances vary—check cities like Detroit.
Penalties and Localities
Violations are felonies: up to 5 years prison and $2,500 fine. No statewide preemption means municipalities enforce stricter rules.
A February 2026 bill proposes allowing double-edged non-folding knives under 5 inches, but it awaits passage.
Best Practices
Carry openly or in pockets for folders; store restricted knives in trunks. Verify local laws via city codes before travel. Michigan favors responsible ownership amid ongoing reforms.
