Butterfly knives (balisongs) are legal to own and carry in Vietnam if they meet specific criteria under the 2023 Law on Firearms, Explosives, and Combat Tools. The Ministry of Public Security (MPS) classifies balisongs as “other tools” under Decree 102/2023/ND-CP, exempting them from weapon restrictions if blades are under 9cm and non-locking. However, concealed carry or use in public remains prohibited under Penal Code Article 321, with violations punishable by fines or confiscation. Recent 2026 compliance directives emphasize stricter enforcement for knives exceeding 5cm in urban areas.
