Utah’s Knife Laws Explained: What You Need To Know

Utah may seem like a place that has lenient knife laws. However, that is only true for the uninitiated.

Their leadership has laid the groundwork for the modern movement of knife laws in America and has inspired other states to establish their knife laws.

What Is The Definition Of A Dangerous Weapon?

According to the Utah Criminal Code Title 76, Part 5 Weapons, a dangerous weapon is –

  1. A firearm
  2. An object that has an intentional capability of causing death or serious physical damage

Certain factors are taken into account to determine whether an object can be considered a “dangerous weapon” or not. These are –

  1. When and where the object was possessed or used
  2. The primary application of the object
  3. The character of the wound, in case a wound is found and was produced with the object
  4. How the knife was used (lawful or unlawful)
  5. Whether the usage or possession of the object poses a potential imminent threat to public safety

Those who fall under either one of two categories of restricted people may not carry or own any knife that falls within the definition of a dangerous weapon.

People who don’t fall under either of these categories are allowed to own and carry (openly and conceal carry) any knives of any size in Utah, regardless of whether the knife is a dangerous weapon or not.

Illegality Based On Areas

According to Utah Code 76-10-505.5, it is illegal to carry any kind of knife, blade, or dangerous weapon inside or near school premises.

School premise refers to –

  • A daycare facility or a pre-school

  • A private or public middle school or high school
  • A private college, university, or a community college

Utah doesn’t have any specific laws when it comes to concealment.

Unless you fall under the definition of a restricted person according to Utah Code – 76-10-503, and as long as it’s not a dangerous weapon, you’re allowed to conceal carry any knife in Utah.

However, unless you have prior permission, it’s illegal to conceal carry any knives inside school premises, so keep that in mind.
