Can You Legally Carry a Knife in Minnesota? Everything You Need to Know

Knives are more than just tools—they’re essential for outdoor enthusiasts, collectors, and those who rely on them for work or personal protection. But if you live in or plan to visit Minnesota, it’s crucial to understand the state’s knife laws before slipping one into your pocket or glove compartment. Minnesota’s knife laws may not be as strict as in some other states, but there are still clear regulations around what you can own, carry, and use—and where.

This guide breaks down Minnesota’s knife laws in simple terms, covering legal ownership, carry restrictions, prohibited places, and more.

What Knives Are Legal to Own in Minnesota?

Minnesota law does not outright ban the ownership of most knives. You can legally own many common types, including:

• Folding knives and pocketknives
• Fixed-blade knives
• Bowie knives
• Hunting and fishing knives
• Throwing knives
• Machetes
• Daggers and dirks

However, the law becomes stricter when it comes to switchblades (automatic knives). According to Minnesota Statute § 609.66, possessing a switchblade knife is generally illegal unless you fall under specific exceptions, such as law enforcement or military personnel with official use.

Carrying Knives in Minnesota: What’s Allowed?

Open Carry vs. Concealed Carry

Minnesota does not distinguish between open carry and concealed carry of knives. That means carrying a knife either visibly or concealed is generally allowed, as long as you are not carrying it with unlawful intent.

The key legal phrase in the statute is whether the knife is being carried “with intent to use it unlawfully against another.” If law enforcement suspects you intend to harm someone, even a legal knife can be grounds for arrest.

Blade Length Limits

Interestingly, Minnesota does not have a blade length restriction in its state statutes. However, local jurisdictions—like Minneapolis or St. Paul—may impose their ordinances regarding blade length. It’s always wise to check local laws before carrying.

Where You Can’t Carry a Knife

Even if a knife is legal, some places are strictly off-limits. These include:

• Schools (K-12 public and private): Possessing a knife on school property is a serious offense and could result in felony charges.
• Courthouses and government buildings: Knives are prohibited, regardless of intent.
• Airports and airplanes: Federal laws prohibit knives of any size or type in carry-on luggage.
• Private property with posted restrictions: If a business or property posts “no weapons” signs, you must comply.

Knife Use and Intent

Possession alone isn’t always the issue—the intent to use the knife unlawfully is what typically triggers legal consequences. If you threaten, intimidate, or harm someone with a knife, the penalties can be severe. Even carrying a legal knife could become a felony charge if prosecutors believe it was used or intended to be used as a weapon.

Common Charges Involving Knives:

Charge Type	Penalty
Possession with unlawful intent	Gross misdemeanor or felony
Possession on school grounds	Felony, possible jail time up to 5 years
Assault with a deadly weapon	Felony, with enhanced sentencing

Minors and Knife Possession

Minnesota does not specifically prohibit minors from owning or carrying knives, but the context matters. If a minor is caught with a knife at school, or using it in a threatening way, the legal consequences can be severe—even if the knife itself is technically legal.

Parents should exercise caution and educate their children on safe and lawful knife use.

Self-Defense and Knife Use in Minnesota

Minnesota does allow for self-defense, but you must prove that your actions were reasonable and necessary. Using a knife in self-defense could still lead to charges if the force is considered excessive or if the threat was not immediate.

In short: A knife may be a legal tool for defense, but use it only as a last resort and when justified.

Final Tips to Stay on the Right Side of the Law

• Avoid carrying knives on school or government property.
• Never carry a knife with the intent to harm or intimidate.
• Keep your knives secured in vehicles and not easily accessible to minors.
• Check for local ordinances in cities like Minneapolis or Duluth.
• When in doubt, consult with a legal expert or local law enforcement.

Conclusion

While Minnesota’s knife laws are more relaxed than those in many other states, they still come with important limitations. Understanding where and how you can legally carry a knife—and what types are restricted—is essential for staying out of legal trouble. Whether you’re a hunter, tradesperson, or everyday carrier, being informed and respectful of the law is your best protection.
