No, switchblades are illegal in New Hampshire under RSA 159:20, which prohibits the manufacture, sale, or possession of automatic knives with blades exceeding 3.5 inches. Local law enforcement, including the New Hampshire State Police, enforces these restrictions, and violations may result in misdemeanor charges. Federal law (15 U.S.C. § 1245) aligns with state restrictions, further limiting interstate transport.
Key Regulations for Switchblades in New Hampshire
- Possession Ban: RSA 159:20 criminalizes possession of switchblades, regardless of blade length, unless exempt under specific exceptions (e.g., law enforcement).
- Manufacture & Sale Prohibition: RSA 159:21 bars the production or distribution of switchblades within the state, with penalties including fines up to $1,000 and imprisonment.
- Transport Restrictions: Federal law (15 U.S.C. § 1245) and state regulations prohibit transporting switchblades across state lines unless for official use, with strict penalties for non-compliance.
Recent legislative scrutiny in 2026 has reinforced enforcement, with the New Hampshire Attorney General’s Office prioritizing crackdowns on illegal knife possession in urban centers like Manchester and Nashua. Courts have upheld convictions under these statutes, emphasizing the state’s zero-tolerance policy. Exceptions exist for antique switchblades over 100 years old, but documentation proving age is mandatory. Consult local ordinances, as some municipalities impose additional restrictions.
