Yes, butterfly knives (balisongs) are legal to own and carry in Wisconsin as of 2024, with no statewide ban. However, local ordinances in cities like Milwaukee or Madison may impose additional restrictions, and concealed carry laws still apply. The Wisconsin Department of Justice has not classified balisongs as prohibited weapons under state statute 941.23.
Key Regulations for Butterfly Knives (Balisongs) in Wisconsin
- Ownership Permissibility: Balisongs are not listed as restricted weapons under Wisconsin Statute 941.23, meaning possession is legal without a permit. However, municipalities may enact stricter local rules.
- Concealed Carry Restrictions: Carrying a balisong concealed in public is prohibited under Wisconsin’s concealed carry laws (Wis. Stat. 941.23(2)), unless the carrier holds a valid concealed carry permit.
- School and Government Property: Federal and state laws prohibit carrying balisongs on school grounds or in government buildings, per 18 U.S. Code § 930 and Wis. Stat. 943.13(1m).
Local Compliance Note: Cities like Milwaukee have historically enforced local ordinances against “dangerous weapons,” though balisongs are not explicitly banned. Always verify municipal codes before carrying. The Wisconsin DOJ’s 2026 regulatory review may introduce further clarifications.
