Wyoming Knife Law – The Complete Guide (In Plain English)

This article was created to be a brief synopsis of the law according to my understanding and is not legal advice. Knifeade is not a legal service provider. Using this site does not create a client/lawyer relationship. Because knife laws can be interpreted differently by different people and entities it is recommended that you consult legal counsel for specific information and guidance.

Do you live in Wyoming? Are you interested in knives? If so, this article is for you! Here we will cover the basics of knife law in the state of Wyoming. This includes what types of knives are legal, who can carry them, and how old you have to be to buy and possess knives.

Is There Statewide Preemption?

A statewide preemption is a law that prohibits individual municipalities from enacting their own laws (knife laws in this case). In other words, the state legislature has decided that all firearms and weapons regulations will be uniform across the entire state.

Wyoming does have a statewide preemption statute, which can be found in WYO Stat § 6-8-104(a). This law states that it is a misdemeanor to carry a concealed deadly weapon in Wyoming, with a few exceptions. It is worth noting that this statute does not mention knives specifically, but rather refers to ‘deadly weapons’.

Because it is vague, most laws specifically referring to knives are made at the city or county level.

Who Can Buy And Carry A Knife In Wyoming?

There are no age requirements to buy or possess a knife in Wyoming. This means that both adults and minors can purchase and carry knives without any legal restrictions.

The only time there is a legal restriction is when the person looking to acquire a knife is doing so with the intent to harm or injure another person.

Concealed Knife Carry Laws In Wyoming

For a state without many knife laws, the concealed carry knife laws of Wyoming are a bit confusing.

The short version is: if you’re eligible for a concealed carry permit (you don’t actually have to have one) and are not looking to harm anyone with your knife then you should be fine to conceal it.

To meet the criteria, you:

  • Have to be 21 years of age or older.
  • Have to be a resident of the United States and a resident of Wyoming for a minimum of six months.
  • Haven’t abused controlled substances within the past year.
  • Haven’t been convicted of a felony ever.
  • Haven’t been convicted for a misdemeanor in the past year
  • Are not legally incompetent.   
  • Haven’t been committed involuntarily to a mental hospital.

At the same time, you also would have to carry a photo ID issued by the state while carrying the knives in a concealed state. This is done in order to prove your residency. As far as non-residents of Wyoming are concerned, they have to obtain and possess a license for concealed weapons from a state that shares reciprocity with the state of Wyoming.

Wyoming doesn’t impose any statutory prohibitions on the general possession and ownership of knives. However, it does provide prohibitions for carrying and wearing a concealed deadly weapon. It is still a subject of dispute as to whether knives are considered deadly weapons or not in this state.

§6-1-104 defines deadly weapons “(a)(iv) Deadly weapon means but is not limited to a firearm, explosive or incendiary material, motorized vehicle, an animal or other devices, instrument, material or substance, which in the manner it is used or is intended to be used is reasonably capable of producing death or serious bodily injury.”

In Conine v. State, a frying pan was considered a deadly weapon since Conine used it to hit the victim during a fight. When Conine appealed his conviction, it was found by the Supreme Court of Wyoming that for an instrument to be considered a deadly weapon, it doesn’t have to cause serious injury to the body; it being capable of doing so is reason enough.

To put it simply, residents of Wyoming are free to carry knives both openly and concededly as long as they fulfill the qualifications for a license of a concealed weapon.  It should be noted that it is not mandatory to own a license, it’s enough to simply qualify for one.

Moreover, there are also no restrictions on buying, selling, giving, and receiving as gifts, and manufacturing of knives.

What Kinds Of Knives Are Legal In Wyoming?

Wyoming has no laws specifically prohibiting or regulating the ownership of any type of knife other than switchblades. This means that all knives, including daggers, dirks, stilettos, and other so-called ‘dangerous’ knives are legal to own and carry in the state.

For clarity, it is legal to own the following types of knives:

  • Folding Knife – It is basically an umbrella term for a pocketknife that has single or multiple blades that can be folded inside a handle while still being small enough to be carried in a pocket.
  • Stiletto – It is a type of dagger or knife that has a needle-like point and a long slender blade. It is basically used as a stabbing weapon.
  • Dagger – It is a type of knife that has two sharp edges, alongside a sharp point. It is designed to be used as a stabbing or thrusting weapon.
  • Dirk –A long thrusting dagger, it was extensively used as a personal weapon by officers of yesteryears who engaged in naval hand-to-hand combats during the Age of Sail.
  • Poniard – This long thrusting knife is known for its lightweight feature. Historically, it was used by upper-class noblemen.
  • Bowie Knife – A fighting knife that has a fixed-blade pattern that was popularised in the 19th century.
  • Balisong, or Butterfly Knife – Also known as a Batangas knife or a fan knife, it is a folding pocket knife. It is marked by the latch on its handle. It is often used as a pocket-utility knife.
  • Switchblade – Also known as an ejector knife, Sprenger, Springer, flick blade, flick knife, pushbutton knife, and automatic knife, it is known for incorporating a locking blade.
  • Gravity Knife – This blade opens its blade located in its handle by using the force of gravity. It is different from a switchblade because it uses a spinning motion to push out the blade from the handle.
  • Lipstick Knife – A rather new invention, it has the body of a lipstick tube and contains a knife inside.
  • Hunting Knife – Evident from its name, it is used during hunting for cutting up the meat and skinning an animal.
  • Sword – Used for thrusting or slashing, it is a melee weapon and consists of a hilt to which the long blade is attached.
  • Push Knife – Also known as a gimlet knife, push dirk, punch dagger, T-handled knife, and Stoßdolch (German), it is a type of dagger that has short blades.

It is important to note that these are only the maximum penalties for each offense. The actual sentence imposed will be determined by the judge based on the severity of the offense and the criminal history of the offender.
