The legal landscape for pocket knives in Minnesota is relatively permissive compared to many other states. Most types of knives, including pocket knives, hunting knives, utility blades, and even specialized knives like butterfly (balisong) and Bowie knives, are legal to own and carry. The significant exception in Minnesota law is the switchblade or automatic knife—these are explicitly prohibited from manufacture, sale, possession, or transfer within the state. Carrying a switchblade is a misdemeanor that can lead to fines up to $1,000, 90 days in jail, or even gross misdemeanor charges if the offense occurs in places like schools or public housing zones, wich may raise penalties to up to one year in jail and a $3,000 fine.
For most knife types, including pocket knives, the law does not set a blade length limit at the state level. Both open and concealed carry are generally allowed as long as the knife user does not possess or carry the knife with unlawful intent. The law becomes more restrictive based on intent—if a knife is carried for the purpose of harming or threatening others, or is used in a threatening manner, it may be classified as a “dangerous weapon” and subject to more severe penalties. Importantly, even legal knives can be deemed illegal if used in a crime or in a threatening way.
There are strict location-based restrictions to remember. Carrying knives of any length is banned on school property (including buses), in courthouses, and certain state buildings. Many parks and public spaces have local ordinances that add further restrictions, sometimes limiting blade length (e.g., Ramsey County prohibits knives with blades of three inches or longer in parks). Thus, it is essential to check specific municipal rules when traveling or carrying knives in densely populated areas.
Minnesota law does not require special permits or training to carry a pocket knife, and there are no age restrictions for mere possession. Nevertheless, individuals with criminal convictions, especially violent offenses, can be subject to additional scrutiny or prohibitions. The broad definition of a “dangerous weapon” means that knife users must exercise common sense and discretion—brandishing or threatening with a knife can bring criminal charges even for otherwise legal knives.
Pocket knives are legal to own and carry in Minnesota for utility or self-defense purposes, provided they are not switchblades and are not carried into restricted locations like schools or courthouses. Responsible, lawful use is key, and checking local ordinances ensures full compliance with the law.
