New Hampshire happens to be one of the most tolerant states in the entire United States. There was a prohibition that applies to switchblade knives that got repealed back in 2010. New Hampshire does not have any general prohibitions in regards to carrying, possession or ownership of knives. There is also statewide preemption in New Hampshire. There are also no local or municipal ordinances that could restrict either knife possession or ownership.

Ammunition, Firearms, and Knives: Authority Of New Hampshire

I. In regards to the extent that is consistent with federal laws, the state of New Hampshire will have authority as well as jurisdiction of the purchase, sale, use, ownership, possession licensing, transportation, taxation, permitting, or any other matter that pertains to firearms, components of firearms, ammunition, any firearms supplies or knives in the state.

II. Upon the valid date of this section, any and all municipal regulations and ordinances that are not authorized under paragraph I that is relative to the sale, ownership, purchase, use, possession, licensing, transportation, taxation, permitting or any other matter that pertains to firearms, firearm components, or the ammunition and firearms supplies or knives will be null and void.
