Yes, butterfly knives (balisongs) are legal to own and carry in Kansas under state law, but local ordinances and federal restrictions may apply.
Kansas statute K.S.A. 21-6304 prohibits concealed carry of any knife with a blade over 3.5 inches without a permit, while open carry remains unrestricted. Local jurisdictions like Wichita and Kansas City, KS, may impose additional blade-length limits or restrictions on possession in public buildings. Federal law under the Switchblade Knife Act (15 U.S.C. § 1244) does not classify balisongs as switchblades, but transportation across state lines requires compliance with TSA guidelines.
Key Regulations for Butterfly Knives (Balisongs) in Kansas
- Blade Length Restrictions: Open carry is permitted regardless of blade length, but concealed carry of knives exceeding 3.5 inches requires a valid Kansas Concealed Carry Weapon (CCW) permit.
- Local Ordinances: Cities such as Wichita and Overland Park may enforce stricter blade-length limits (e.g., 2.5 inches) in municipal buildings or parks.
- School and Government Property: Possession of any knife, including balisongs, is prohibited on K-12 school grounds and state/county facilities under K.S.A. 21-6306.
Federal regulations under the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) classify balisongs as “non-switchblade” knives, exempting them from the Switchblade Knife Act’s restrictions. However, transporting them in checked luggage requires secure packaging to prevent accidental deployment. Kansas law does not mandate blade locking mechanisms, but law enforcement may scrutinize balisongs if used in a threatening manner. Always verify municipal codes before carrying in urban areas.
