New Hampshire Knife Laws

Broadly permissive · read 2026-09-04

New Hampshire is one of the more permissive provinces in the union for edged steel. Broadly permissive with preemption.

New Hampshire sets no statewide blade-length ceiling on concealed carry. That does not mean any blade may be concealed — intent, pattern and place still govern, and a court will read all three.

Open carry carries no statewide length ceiling in New Hampshire. Sheathed, visible and plainly for work or display is the safest posture anywhere in the union.

New Hampshire preempts local ordinance. One rule governs the whole province, and a city may not write a stricter one.

Can this house ship steel to New Hampshire?

Shipping is possession, not carry — most provinces permit ownership of what they forbid on the street. Warborn Blades ships to buyers of age in the United States and Canada, and the counter refuses a barred road before a card is ever touched.
