Utah boasts some of the most permissive knife laws in the U.S., allowing open and concealed carry of virtually any knife without blade length limits or type restrictions. Statewide preemption (Utah Code § 53-5a-108) prevents local governments from adding stricter rules, ensuring uniformity. As of 2026, no changes apply—knives are legal tools for all non-restricted adults 18+.
Core Carry Rules
Open carry is unrestricted for any knife—fixed blades, folders, or large sheaths—anywhere not prohibited. Concealed carry legalized statewide via 2021 HB 60, amending § 76-10-504 to exclude knives from “dangerous weapon” bans (now firearms-only).
No permit needed; pocket knives or sheathed blades qualify as concealed legally. “Knife” undefined broadly, avoiding bans on autos, balisongs, or dirks.
Dangerous Weapon Definition
A knife becomes a “dangerous weapon” (§ 76-10-501) only by intent or use: brandished threateningly or in crimes. Peaceful carry—even 12-inch bowies—stays legal. Restricted persons (felons, domestic violence convicts per § 76-23-102) face felony possession if “dangerous,” but everyday knives often exempt via case law (State v. Ames).
Allowed Knife Types
All common varieties legal:
- Switchblades, autos, OTFs.
- Butterfly/balisong.
- Disguised (belt buckle, cane).
- Daggers, dirks, bowies.
- Gravity knives.
Federal switchblade ban lifted 2018 (18+); Utah defers. No blade length cap statewide.
Prohibited Locations
Carry bans in sensitive spots (§ 76-10-530):
- Schools (K-12, 1000 ft radius for blades ≥2.5″).
- Courthouses, prisons.
- Airports (TSA zones).
- Secure government buildings.
- Posted private property.
Permitless firearm carriers exempt some; knives follow suit indirectly.

| Aspect | Rule | Statute |

Age and Restricted Persons
18+ general carry; minors ok with parental tools but schools zero-tolerance. Felons/prohibited avoid “dangerous” knives—hunting blades often ok per courts. CFP holders (firearm permit) exempt extra restrictions.
Self-Defense Applications
Knives qualify as arms (§ 76-2-402); proportional force justified against threats. No duty to retreat in public. Brandishing alone risks § 76-10-506 charges if menacing.
