Is There Statewide Preemption?

Statewide preemption is a law that prevents individual municipalities from enacting their own laws (knife laws in this case). It means that the state legislature has the primary jurisdiction over firearms and weapons regulations, promoting uniformity across the entire state.

In Wyoming, there is a statewide preemption statute under WYO Stat § 6-8-401, which states that the regulation of firearms, weapons, and ammunition is preempted by the state, thus ensuring uniformity across Wyoming.

Who Can Buy And Carry A Knife In Wyoming?

There isn’t a state-level age restriction to buy or possess a knife in Wyoming, although individual retailers may have their own age restrictions. The only state-level restriction pertains to possessing a knife with the intent to harm or injure another person.

Concealed Knife Carry Laws In Wyoming

In Wyoming, the laws around concealed carry of knives can appear confusing at first. Wyoming law provides that it is an offense to wear or carry a “concealed deadly weapon” unless one possesses a valid weapon permit or is otherwise eligible to hold a weapon permit. In general, persons at least 21 and not convicted of a violent crime or drug offense are eligible. However, knives are not generally considered deadly weapons, and the concealed carry of a deadly weapon is not an issue for persons at least 21 who are not ineligible to hold a weapon permit.

The criteria for eligibility include:

  • Being 21 years of age or older
  • Being a resident of the United States and a resident of Wyoming for a minimum of six months
  • No substance abuse within the past year
  • No felony convictions
  • No misdemeanor convictions in the past year
  • Not being legally incompetent
  • No involuntary commitment to a mental hospital (though this can vary based on the specifics of the commitment)

Remember, while carrying the knives in a concealed state, you would need to have a photo ID issued by the state to verify your residency. Non-residents of Wyoming would need to obtain and possess a license for concealed weapons from a state that Wyoming recognizes.

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

Wyoming knife laws are quite lenient due to the lack of specific regulations surrounding knives. The ambiguity in the law tends to work in favor of knife enthusiasts as it doesn’t technically define the types of knives to be carried in a concealed manner in the state of Wyoming; therefore, most are regarded as legal to be carried.
