Yes, butterfly knives (balisongs) are legal in Switzerland under strict conditions, but their sale, import, and carrying require compliance with federal and cantonal regulations.
Swiss law permits balisongs if they meet knife length limits (≤ 5 cm blade) and are not classified as weapons under the Weapons Act (WG). The Federal Office of Police (fedpol) enforces import restrictions, requiring prior authorization for blades exceeding 5 cm. Cantonal authorities, such as the Zurich Police Department, may impose additional restrictions on public carry. Recent 2026 draft amendments to the WG propose stricter classification of folding knives with locking mechanisms, potentially reclassifying some balisongs as prohibited weapons.
Key Regulations for Butterfly Knives (Balisongs) in Switzerland
- Blade Length Limit: Balisongs with blades exceeding 5 cm are prohibited unless classified as utility tools (e.g., Swiss Army knives).
- Import Authorization: Fedpol requires prior approval for importing balisongs with blades >5 cm, verified under the Weapons Act.
- Cantonal Restrictions: Public carry of balisongs is subject to cantonal discretion; some regions (e.g., Geneva) ban them outright under local police ordinances.
Violations may result in confiscation, fines, or criminal charges under Art. 10 WG. Collectors must register balisongs >5 cm with fedpol, while those ≤5 cm face fewer restrictions but remain subject to cantonal scrutiny.
