Yes, butterfly knives (balisongs) are legal to possess and carry in the Philippines, provided they meet specific regulatory standards. The Philippine National Police (PNP) and the Bureau of Firearms and Explosives (BFAR) classify balisongs as “bladed weapons” under the Comprehensive Firearms and Ammunition Regulation Act (RA 10591) and PNP Memorandum Circular No. 2021-001. While ownership is permitted, concealed carry requires a valid permit-to-carry (PTC) from local PNP offices. Recent 2026 compliance shifts emphasize stricter verification of blade length (under 3 inches) and manufacturing standards to curb unauthorized use.
Key Regulations for Butterfly Knives (Balisongs) in Philippines
- Blade Length Restrictions: Balisongs with blades exceeding 3 inches (7.62 cm) are classified as “deadly weapons” under PNP guidelines, requiring registration and a permit-to-carry for public transport.
- Manufacturing Standards: Only balisongs produced by licensed manufacturers (e.g., registered under the Department of Trade and Industry) are legally marketable; homemade or imported units must undergo BFAR inspection.
- Public Carry Permits: Open or concealed carry in urban areas (e.g., Metro Manila, Cebu City) mandates a PNP-issued Permit-to-Carry (PTC), with renewals subject to background checks and local ordinances.
