This article was created to be a brief synopsis of the law according to my understanding and is not legal advice. Knifeade is not a legal service provider. Using this site does not create a client/lawyer relationship. Because knife laws can be interpreted differently by different people and entities it is recommended that you consult legal counsel for specific information and guidance.
Minnesota is home to fishers and hunters who often use knives as a tool. However, the use of knives within gangs and other criminal activities has forced the government to regulate the use of knives. Knife laws are mainly a state issue, and each state has its own rules.
In Minnesota, knife laws are fairly strict, especially concerning automatic knives. To ensure that you remain on the right side of the law, here is what you need to know about knife laws in Minnesota.

Is There A Statewide Preemption For Knife Laws In Minnesota?
Statewide preemption refers to a state law that prevents local jurisdictions from enacting or enforcing their own, potentially stricter, regulations on a particular subject. When a statewide preemption exists, this ensures a uniform set of rules across the entire state, creating consistency and eliminating potential confusion or legal pitfalls as individuals move from one local jurisdiction to another.
Minnesota does not have a statewide preemption for knife laws. This means local cities, towns, and municipalities are free to enact and enforce their own knife laws that can be more restrictive than state laws.
