New Hampshire boasts some of the most permissive knife laws in the U.S., allowing law-abiding citizens broad rights to own, carry, and use knives openly or concealed. This guide breaks down key regulations, restrictions, and best practices based on current statutes as of 2026.
Legal History
New Hampshire reformed its knife laws significantly in 2010 with House Bill 1665, which removed prohibitions on dirks, daggers, stilettos, and switchblades from RSA 159:16. This change legalized possession and carry for non-felons, aligning with the state’s “Live Free or Die” motto. Statewide preemption under RSA 159:26 prevents local governments from adding stricter rules.
Allowed Knives
Virtually all knives are legal to own, buy, sell, and carry in New Hampshire, with no blade length limits. Common types include:
- Switchblades and automatics
- Butterfly (balisong) knives
- Assisted-opening knives
- Dirks, daggers, bowies, and stilettos
- Disguised knives (e.g., no bans on possession alone)
Only blackjacks, slung shots, and metallic knuckles remain prohibited under RSA 159:16.
Carry Rules
Open and concealed carry of any legal knife is permitted without a permit for eligible adults. New Hampshire’s constitutional carry status (post-2017 SB 12 repeal of RSA 159:4) extends to knives, with no restrictions by type or mechanism. Intent to use unlawfully can lead to charges, but everyday carry is unrestricted.
Who Can’t Carry
Convicted felons (especially those with crimes against persons/property or drug felonies) are banned from possessing “deadly weapons” like knives under RSA 159:3. No specific state age minimum exists for ownership, though federal rules may apply to sales, and minors should have supervision. Law enforcement and military get duty-related exceptions.
Prohibited Places
Knives qualify as “deadly weapons” (RSA 625:11, V) and are banned in:
- Courthouses (RSA 159:19)
- Schools and school events (general prohibition)
- Certain government buildings or secured areas
Parks and other public spots are generally fine, but caution is advised in volatile environments like hospitals.
Penalties
Violations like felon possession are Class B felonies, punishable by up to 7 years in prison. Unlawful carry with criminal intent may be a misdemeanor or escalate to felony based on use. Recent 2026 legislation (HB 609) strengthened preemption, blocking stricter local or agency rules on knives.
Practical Tips
Always store knives securely at home and avoid brandishing them unnecessarily to prevent misunderstandings. For reciprocity or travel, note federal bans on ballistic knives (15 U.S.C. § 1245). Check official RSA statutes or consult a local attorney for personalized advice, as laws evolve.
