Butterfly Knife laws in Connecticut

In Connecticut, butterfly knives, also known as balisongs, are generally considered illegal to sell, offer to sell, deliver, possess, or transport under Connecticut General Statutes Section 53-206. This statute defines illegal weapons to include any knife that "can be opened by a flick of the wrist or by mechanical contrivance" and prohibits the possession of such weapons with intent to use them unlawfully. While the statute does not explicitly name "butterfly knife," its mechanism of opening generally falls under this definition. The law further specifies that possession of an illegal weapon is a class D felony. Violations of Connecticut's illegal weapon statutes can result in significant penalties. A class D felony conviction is punishable by imprisonment for not more than five years, a fine of not more than five thousand dollars, or both. It is important to note that intent to use the weapon unlawfully is generally a component of the offense, however, possession alone may be viewed critically by law enforcement. Furthermore, specific local ordinances in Connecticut municipalities may impose additional restrictions or prohibitions regarding the possession and carrying of such knives. While Connecticut law generally restricts butterfly knives, there might be nuances regarding open carry versus concealed carry. However, the overarching prohibition on possession is the primary concern for residents. For travelers, it is crucial to be aware that butterfly knives are prohibited by the Transportation Security Administration (TSA) from being carried in carry-on luggage on aircraft. Residents and visitors should exercise extreme caution and consult with local law enforcement or legal counsel for the most current and specific interpretations of the law, as well as any local ordinances that may apply.
