Kentucky’s knife laws are among the most permissive in the U.S., allowing ownership, open carry, and concealed carry of virtually any knife type for adults 21 and older under constitutional carry rules. No blade length limits or bans on switchblades, balisongs, or daggers exist statewide as of 2026, making it a knife-friendly state.
Ownership and Types Allowed
Kentucky bans no knives—switchblades, automatic knives, ballistic knives (federal exception), dirks, bowies, balisongs, and undetectable blades are all legal to own and buy without registration.
KRS 500.080 defines “deadly weapons” as any knife except an “ordinary pocket knife or hunting knife,” but this classification affects only concealed carry for minors, not ownership. Minors can possess knives openly without age restrictions.
Open Carry Rules
Open carry of any knife is unrestricted for all ages, anywhere not specifically prohibited—belt sheaths, hip straps, or visible pockets qualify as open. Even a cavalry saber on your hip is legal in Louisville streets, per case law and statutes like KRS 527.020 focusing solely on concealed carry. Schools ban deadly weapons (Class D felony under KRS 527.070).
Concealed Carry Guidelines
Since KRS 237.109 (Constitutional Carry, effective June 27, 2019), adults 21+ can conceal any knife—including deadly weapons like autos or daggers—without a permit, treating them like firearms. A pocket-clipped folder partially hidden under a shirt counts as concealed but remains legal post-2019. Under 21: Limited to ordinary pocket/hunting knives concealed; other types require a CCDW permit (KRS 237.110).
Restricted Locations
- Schools, universities, and K-12 grounds: Deadly weapons prohibited (felony).
- Courthouses, jails, airports, and posted private property.
- Federal facilities follow TSA rules (blades under 2.36″ for carry-on irrelevant here).
Vehicles: Full constitutional carry applies—no glovebox restrictions for 21+.
Penalties for Violations
No civil forfeiture for mere possession errors.
Key Definitions
- Ordinary Pocket Knife: Folding knife with everyday utility, no fixed blade—courts assess case-by-case.
- Hunting Knife: Fixed blade for field use.
- Preemption: State law overrides local bans since 2019.
