Kentucky maintains some of the most permissive knife laws in the U.S., allowing adults broad rights to own, open carry, and conceal pocket knives without permits. Since the 2019 Constitutional Carry law (KRS 237.109), individuals 21 and older face no state restrictions on concealed carry of most knives, including those deemed “deadly weapons” except ordinary pocket or hunting knives for minors.
No blade length limits or bans on switchblades, balisongs, or automatics apply statewide, though schools and courthouses prohibit all weapons.
Ownership and Possession Rights
All knives are legal to own in Kentucky, from pocket folders to fixed blades, with no registration or purchase restrictions. Minors under 18 face no possession bans but cannot conceal “deadly weapons” beyond ordinary pocket or hunting knives, defined loosely as typical folding tools under 4 inches. Felons regain knife rights post-sentence unless violent crimes bar possession; confirm via attorney.
State preemption partially protects via KRS 65.870 and 237.104, overriding some local rules, but municipalities like Louisville may add minor ordinances.
Open and Concealed Carry Rules
Open carry of any pocket knife enjoys full legality for all ages on streets, vehicles, or businesses absent “no weapons” signs. Constitutional carry eliminates CCDW permit needs for concealed blades over 21, reversing prior bans on non-pocket knives under KRS 527.020. Under-21s limit to ordinary pockets (non-locking folders or small hunters) concealed; others risk Class A misdemeanor charges: up to 12 months jail, $500 fine.
Vehicles allow knives anywhere except immediate driver reach if intoxicated, aligning with firearm rules.
Prohibited Locations
KRS 527.020 bans all knives on K-12 school grounds, buses, or events—felony for deadly weapons, misdemeanor otherwise. Courthouses, jails, airports, and legislative buildings prohibit via KRS 237.115; postsecondary campuses permit outside classrooms. Private property owners dictate via posted notices.
Self-Defense and Use
Knives qualify for proportional self-defense under KRS 503.050-503.120’s Stand Your Ground—no retreat duty in public if reasonably fearing harm. Brandishing alone risks menacing charges (KRS 508.050) unless justified; post-use, report to police immediately. Courts upheld defenses in proportional cases, like fending off assaults.
Best Practices
Clip pocket knives visibly to skirt debates; carry 3-4 inch folders for everyday tasks. Check local codes in cities; update via Kentucky State Police site. Engrave for recovery; sheath fixed blades.
