New Hampshire maintains one of the most permissive legal frameworks for pocket knives in the United States, allowing law-abiding citizens broad rights to own, carry, and use them. This landscape reflects the state’s “Live Free or Die” ethos, shaped by key legislative reforms.
Core Statutes
New Hampshire Revised Statutes (RSA) Chapter 159 governs weapons, with RSA 159:16 prohibiting only blackjacks, slung shots, and metallic knuckles—knives of all types, including pocket knives, are explicitly not listed.
RSA 159:26 establishes statewide preemption, preventing cities or towns from enacting stricter knife rules. Felons convicted of crimes against persons, property, or drugs cannot possess knives under RSA 159:3, treating them as deadly weapons per RSA 625:11.
Carry Regulations
Open carry of pocket knives faces no restrictions for eligible adults, regardless of blade length or type. Concealed carry is equally unrestricted, aligning with New Hampshire’s constitutional carry for firearms since 2017 (RSA 159:6), which does not limit knives. No blade length limits apply statewide, and local variations are barred by preemption.
Pocket Knives Defined
Pocket knives typically include folding knives like manual folders (e.g., slip joints, lockbacks) and assisted-openers, all legal without caveat. Automatic knives (switchblades) were legalized in 2010 via HB 1665, removing bans on stilettos, daggers, dirks, and switch knives from prior RSA 159:16. Disguised or ballistic knives remain unregulated unless used criminally.
Prohibited Locations
Knives qualify as “deadly weapons” and are banned in courthouses (RSA 159:19). Schools, airports, and government buildings often prohibit them via federal or policy rules; private property owners can post no-knife signs. Prisons bar knives as “implements for escape” (RSA 642:7).
Historical Reforms
Pre-2010, New Hampshire banned switchblades and similar blades, but Rep. Jenn Coffey’s HB 1665 (effective 2011) repealed these, making it the first state to fully deregulate knives. HB 1178 (2017) further shields against federal knife restrictions. These changes prioritize individual rights over prior restrictive norms.
Federal Overlaps
Federal law bans interstate transport of switchblades (15 U.S.C. § 1241-1245), but New Hampshire ignores enforcement of conflicting federal rules per HB 1178. Switchblades over 2 inches remain federally restricted for mail, though intrastate possession is state-governed. Travelers must check destinations like Massachusetts, where rules tighten sharply.
Exceptions and Penalties
Law enforcement and military get duty-based exemptions. Minors face no sales bans specific to knives, unlike BB guns. Violations like felon possession or unlawful intent carry misdemeanor charges, fines, confiscation, or jail; intent to harm elevates penalties.
Practical Advice
Verify non-felon status before carrying; store securely at home if prohibited. For EDC (everyday carry), opt for compact folders under 4 inches to minimize misinterpretation elsewhere. Consult NH statutes directly or a local attorney for updates, as laws evolve. Cross-state travel demands awareness—NH’s freedom contrasts neighbors’ restrictions.
