Yes, Butterfly knives (balisongs) are legal to own and carry in Portugal as of 2024, provided they meet specific criteria outlined by national and EU regulations. The Portuguese National Authority for Civil Protection (ANPC) and the Public Security Police (PSP) enforce restrictions on blade length and concealed carry, aligning with EU-wide knife legislation. Recent 2026 compliance shifts emphasize stricter penalties for carrying knives in public spaces without justification.
Key Regulations for Butterfly Knives (Balisongs) in Portugal
- Blade Length Limit: Balisongs with blades exceeding 10 cm are classified as prohibited weapons under Portuguese law (Decreto-Lei n.º 15/93, amended by Lei n.º 5/2006). Possession of such knives without a valid reason (e.g., professional use) may result in confiscation or criminal charges.
- Concealed Carry Prohibition: Carrying a balisong in public without explicit justification (e.g., hunting, fishing, or trade-related activities) is illegal. The PSP may detain individuals found with concealed knives, citing Article 27 of the Weapons and Ammunition Law.
- Age Restrictions: Minors under 16 years old are prohibited from purchasing or possessing any type of knife, including balisongs, unless supervised for educational or professional purposes. Retailers must verify age via ID before sale.
Non-compliance risks include fines up to €1,200 or imprisonment for up to 1 year, per Article 28 of the same law. Travelers should note that EU customs regulations apply; balisongs with blades over 10 cm may be seized upon entry. For legal certainty, consult the ANPC’s 2024 Guia de Armas Brancas or a licensed Portuguese attorney.
