Knife Laws in New Jersey: Is It Illegal to Carry a Knife in New Jersey?

Knife laws in New Jersey are quite complicated as compared to other regions in the US, such as Illinois, Michigan, New York, etc. At the same time, New Jersey has some strict laws regulating knife possession and use.

Knife enthusiasts and regular individuals who are not aware of those laws can find themselves in great trouble, including a long prison time or/and a good amount of fine.

The only thing that can save them is not to educate them about all the knife laws within the state. Such as which knives are illegal and which are legal to possess, lawful use and intent, prohibited from certain places.

Following these laws and keeping them in mind when possessing a knife can save them from criminal charges and fines – not to mention the lawful use of knives. Therefore, let’s begin with the knife laws.

Types of Knives Regulated in New Jersey

New Jersey law defines a knife as “any instrument or device capable of cutting, stabbing, or causing other physical injuries.” In simple terms, any device having a sharp edge or sharp blade that can be used to cut, stab, or cause severe injury to others is a knife. For instance, pocket knives, gravity knives, switchblade knives, ballistic knives, etc.

In New Jersey, almost all types of knives are found. But not all of them are legal to possess, carry, sell, or manufacture. On the other hand, not all knives are prohibited either. Let’s take a look at which knives are legal and which are not.

Knives Legal to Possess in New Jersey

  • Pocket knife.
  • Butterfly knife.
  • Hunting and fishing knives.
  • Lipstick knives.
  • Swords
  • Swiss army knives.
  • Throwing stars.
  • Bowie knives.
  • Any knife with an explainable and lawful purpose except prohibited knives.

Knives Illegal to Possess in New Jersey

As per 2C:39-3, these knives are prohibited in New Jersey and prohibited from possession:

  • Gravity knives.
  • Switchblades.
  • Daggers.
  • Dirks.
  • Ballistic knives.
  • Stilettoes.
  • Razor blade embedded in wood.
  • Any knife without any explainable and lawful intent or use.

Preemption Restrictions in New Jersey

New Jersey knife laws may be very strict, but the good thing is that this state doesn’t have statewide preemptions. I assume you are not aware of the term “Preemption Law.” Well, no preemption laws mean that if cities came up with stricter laws regulating knives, then the state law that regulates knife laws can stop the enforcement of the laws that cities pass.

An example would make things easier for you. New Jersey State law regulates knife possession and use. And according to state law, five inches is the maximum blade length for all legal knives. But if a city passes an ordinance where it is illegal to carry a knife with a blade length of 3 inches, then state law can cancel the ordinance.

Federal Restrictions

In New Jersey, Federal laws also regulate the possession and sale of certain types of knives, which are:

  1. Switchblade and ballistic knives are illegal.
  2. Federal Switchblade Act prohibits the possession, carry, sale, transport, shipment, and distribution of switchblade is prohibited.
  3. Ballistic knives are also prohibited to possess and sold.
  4. Transportation of any folding knife that has a blade longer than 5 inches are illegal (Note: Written permission may allow transporting).

Possession and Carrying of Knives New Jersey

Possession of certain knives may be allowed in New Jersey. But carrying them can be an issue and put you in a lot of trouble if you are not aware of the laws regarding knife possession and carry, which are:

Open Carry

It’s not an issue in New Jersey to openly carry a knife. An individual can open carry any knife as long as the knife is not prohibited and the blade length doesn’t exceed 5 inches or the knife size overall 10 inches. At the same time, the knife holder must be at least 18 to carry a knife.

Conceal Carry

As per Section 133.02, it is illegal to conceal or carry any knife. But if you have a license for activities such as hunting, fishing, and other recreational activities, you can conceal carry knives. However, all prohibited knives are not included in this law – meaning concealed carrying of prohibited knives is illegal as well.

Lawful Possession

It is legal to carry knives except prohibited ones to carry if you have an explainable lawful intent and use, according to 2C:39-3. This section states that one can carry a knife if that individual has a lawful intent and purpose to possess the knife. For example, hunting, fishing, self-defense, etc. But all prohibited knives are illegal to carry even if your intentions are lawful.

Unlawful Possession

As per State Law 2C:39-3 and 2C:39-4, it is illegal to possess and use knives unlawfully. As I mentioned earlier, the unlawful possession of a knife is illegal. Likewise, using a knife for lawful purposes, such as robbing, assaulting, and harming others, is illegal as well.

Knife Used as Weapon

According to the New Jersey State Law 2C:39-1, a “Weapon” refers to “anything that is readily capable of lethal use and inflicting serious bodily injury.” The law further states a knife can be a weapon, and gravity knives, switchblades, daggers, dirk, stilettoes, ballistic knives, and any knife with unexplainable intent are considered weapons.

Since certain knives are considered weapons, possessing and carrying those knives are illegal, as well as using them as weapons.

As per 2C:39-4, if anyone uses a knife for unlawful purposes against others or other’s property, it will be considered a crime of the third degree.

On the other hand, 2C:39-5 states that using a knife knowingly against someone in a circumstance that is not manifestly appropriate is also illegal and considered a crime of the fourth degree.

Knife for Self-Defense

In New Jersey, it is legal to possess and use a knife for self-defense. Since self-defense is lawful – thus, as per 2C:39-3, 2C:39-4, 2C:39-5, it is legal to use a knife only for lawful activities that include self-defense. At the same time, 162 A.3d 270 (2017) states that one can carry and possess a knife at home for lawful purposes such as self-defense.
