Yes, butterfly knives (balisongs) are legal to own and carry in New Hampshire as of 2024, with no state-level restrictions. Local municipalities, however, may impose additional ordinances, and federal law prohibits interstate transport of balisongs with blades exceeding 2.5 inches without proper licensing. The New Hampshire Department of Safety has not issued specific advisories on balisongs, but recent 2026 legislative proposals suggest potential future scrutiny under concealed carry regulations.
Key Regulations for Butterfly Knives (Balisongs) in New Hampshire
- No State Prohibition: New Hampshire RSA 159:26 does not classify balisongs as prohibited weapons, allowing ownership and open carry without restrictions.
- Local Ordinance Risks: Cities like Manchester and Portsmouth may regulate blade lengths or carry methods via municipal codes; compliance requires checking local statutes.
- Federal Transport Rules: Under 18 U.S. Code § 930, transporting balisongs across state lines with blades over 2.5 inches without a license violates federal law, even if state laws permit them.
