Concealed Carry

The Law in Detail

Key statutes: Minn. Stat. §§609.66, 609.02 subd. 6

Minnesota's switchblade restriction under §609.66 carries up to 90 days and $1,000 generally, rising to one year and $3,000 in public housing, park, or school zones. In In re Welfare of C.R.M., 611 N.W.2d 802 (2000), the Minnesota Supreme Court required proof the student knowingly possessed the knife before a felony school-zone conviction could stand. There is no statewide preemption, and an odd result of the statute is that automatic knives on school grounds can draw lighter penalties than ordinary folders there.
