Butterfly Knife laws in Minnesota

In Minnesota, butterfly knives (also known as balisongs) are subject to restrictions under state law. While Minnesota Statutes section 624.711 defines "dangerous weapon" broadly to include knives with switchblade or automatic spring mechanisms, it does not explicitly name butterfly knives as prohibited *per se*. However, the *manner* in which a butterfly knife is possessed or carried can lead to legal consequences. Generally, concealed possession of any "dangerous weapon" is prohibited under Minnesota Statutes section 624.713, which classifies such a violation as a gross misdemeanor. Open carry of a butterfly knife may be permissible, but this is subject to interpretation and local ordinances. Violations related to the possession or carrying of a butterfly knife, depending on the specific circumstances and classification under dangerous weapon statutes, can result in penalties ranging from fines to jail time. A gross misdemeanor conviction under Minnesota Statutes section 624.713 for illegal possession or carrying of a dangerous weapon can carry a maximum penalty of one year in jail and a fine of up to $3,000. It is crucial to note that local municipalities may have their own ordinances that further restrict or prohibit the possession of specific types of knives, including butterfly knives, even if state law is less explicit. While there are no explicit statutory exemptions for butterfly knives in Minnesota, a key practical consideration for residents and travelers is the distinction between concealed and open carry. The Transportation Security Administration (TSA) prohibits butterfly knives in carry-on luggage, though they may be permitted in checked baggage if properly secured. Travelers are advised to check TSA regulations thoroughly before flying. Furthermore, enthusiasts or collectors should be aware that butterfly knives are often treated similarly to switchblades in legal contexts, meaning possession and carry laws that apply to one may apply to the other. Staying informed about both state and local laws is essential to ensure compliance.
