If you’re living in or visiting South Dakota and wondering about the rules around carrying a knife, you’re in the right place. South Dakota has some of the most relaxed knife laws in the U.S., but that doesn’t mean there are no rules at all. Whether you’re carrying a knife for work, hunting, or personal use, it’s important to know where, when, and how it’s legal.
Here’s a simple guide to help you understand the knife laws in South Dakota in 2025.
What Types of Knives Are Legal in South Dakota?
Good news! South Dakota allows people to own and carry almost any kind of knife. These include:
Common Legal Knives:
- Pocket knives (folding blades)
- Bowie knives (large fixed-blade knives)
- Switchblades (automatic opening)
- Butterfly knives (also called balisong)
- Hunting knives
- Utility knives or box cutters
Basically, there are no specific knives that are banned in the state, making South Dakota one of the more knife-friendly states in the country.
Carrying a Knife: What’s Allowed?
Open Carry
You can openly carry any legal knife in South Dakota. There’s no law stopping you from wearing a knife on your belt or visibly carrying it in public.
Concealed Carry
South Dakota also allows concealed carry of knives. This means you can carry a knife in your pocket or bag without worrying about breaking the law. Unlike some states, there is no blade length limit for concealed knives here.
But remember, just because it’s legal doesn’t mean it’s always a good idea. Using your knife carelessly or threatening someone with it can still land you in serious trouble.
Where You Cannot Carry Knives
Even though the laws are relaxed, some places do not allow knives—no matter what type or size. These include:
- Schools and school grounds
- Government buildings
- Courthouses
- Airports (past security checkpoints)
- Private properties where knives or weapons are not allowed
It’s always smart to check signs or ask before entering such places with a knife.
Special Rules for Law Enforcement and Military
If you are a police officer, soldier, or on active duty, you might be allowed to carry knives in places where regular people can’t. This depends on whether you’re carrying it for work or under official duty. But outside work or uniform, the same rules as civilians apply.
What Happens If You Break the Law?
If you carry a knife where it’s not allowed—like inside a school or courtroom—you could:
- Get fined
- Face misdemeanor or felony charges
- Possibly go to jail
Also, local towns or cities in South Dakota might have their own extra rules. So, it’s always wise to check city laws before carrying your knife around.
South Dakota has some of the most relaxed knife laws in America. You can legally carry most types of knives, both openly and concealed. But it’s still important to be careful. Never carry knives into restricted areas like schools or airports, and always use them responsibly.
Whether you’re carrying a knife for outdoor work, self-defense, or as a hobby, being aware of the rules helps you stay out of trouble and enjoy your freedom safely.
