New Hampshire State Knife Laws

New Hampshire is a remarkably good state for knife ownership and carry since a major overhaul of their laws beginning in the second decade of the 21st millennium.

In fact, except for one quibbling potential restriction on knives with integral “D” handguards or knuckleduster handguards you may own and carry absolutely any other kind of knife you would like to in the state.

To say that this is a breath of fresh air among all the other stereotypically restrictive New England states is an understatement!

The laws concerning knives in New Hampshire really only concern themselves with criminal activity using a knife, not defining and restricting any particular kind of knife do two features, action, blade length or anything else.

There are a few minor laws that you would be wise to learn and remain cognizant of, particularly when it comes to selling and transferring knives, but these are all minor affairs.

To top it all off, New Hampshire also has strong preemption laws meaning you will be dealing with one set of rules throughout while in the state. We will get to the good news just below the break!

What You Need to Know

  • What Kind of Knives Can I Own?: Any kind of knife.
  • Can I Carry a Knife Concealed Without a Permit?: Any kind of knife that does not have a full “D” or knuckle duster guard.
  • Can I Carry a Knife Concealed With a Permit?: Any kind of knife that does not have a full “D” or knuckle duster guard.
  • Can I Carry a Knife Openly?: Any kind of knife that does not have a full “D” or knuckleduster guard.

General Ownership

New Hampshire references knives in their definition of “deadly weapon”, specifically any knife that is used, intended to be used, or threatened to be used and is capable of producing death or serious bodily injury, with serious bodily injury being defined as harm to the body which causes severe, permanent or protracted loss or impairment of health or the functionality of any body part.

To this end, any knife of any kind is a deadly weapon in New Hampshire, but this is not a blanket prohibition; New Hampshire is concerned with how dangerous tools are used as weapons in the commission of crime, not with banning everything under the sun in a misguided attempt to reduce criminality

This is incredibly sane in a region that is known for invasive Big Brother government policies.

That being said, no felon may be in possession of a knife or other deadly weapon as defined above and in the statutes. This applies for felons charged and prosecuted in the state of New Hampshire as well as those who have felony records from elsewhere.

Is also worth being aware of New Hampshire’s prohibition on metallic, or brass, knuckles, and that whosoever has them in their possession, sells or transfers them, or carries them on their person is guilty of a misdemeanor.

I mention this only because there are a few kinds of modern and vintage knives that have an integrated, large handguard that wraps around the hand and some old military knives with knuckleduster style finger guards. These knives are potentially illegal in New Hampshire.

But the good news keeps on coming, as New Hampshire has very solid preemption rules concerning knives, and no municipality will be able to enact laws that are more stringent than the state laws governing the ownership and carry of knives and other edged weapons.

Concealed Carry, No Permit

A person may carry any kind of knife they desire concealed in New Hampshire without benefit of a permit so long as they are not carrying it or using it for any criminal purpose.

Concealed Carry, With Permit

New Hampshire makes no distinction between carry of any knife with a permit as opposed to without a permit, and you may carry any knife you choose that so long as you are not using it for any criminal purpose or carrying it with criminal intent.

Open Carry

Open carry of all kinds of permitted knives is completely legal in New Hampshire.

Prohibited Places

There are no explicitly forbidden places that will keep you from carrying a knife in New Hampshire, but now as always it is usually in your best interest to exercise a certain amount of care before taking a blatant weapon into any sensitive area like a school, government installation, hospital, courthouse and so forth.

Assessment

There is at least one state in New England that still believes in freedom and that state is New Hampshire. New Hampshire has excellent knife laws by any state’s standards, not just New England’s, and you can carry virtually any kind of knife you want openly or concealed with no permit necessary.

Aside from a questionable restriction on any knife that has an integrated hand and closing or knuckleduster handguard you won’t have any issues whatsoever when it comes to knives in this state.
