Brass knuckles are not illegal in Kentucky. You can own them, keep them at home, and if you’re 21 or older and can lawfully possess a firearm, carry them concealed without a permit. The state does classify them as a deadly weapon, though, so the same rules that limit where you can take a handgun apply to brass knuckles, and violating those location restrictions can be a felony.
How Kentucky Classifies Brass Knuckles
Kentucky statutes use the term “artificial knuckles.” Under KRS 500.080, artificial knuckles made from metal, plastic, or similar hard material are a “deadly weapon,” grouped with firearms, certain knives, and clubs.1Kentucky Legislative Research Commission. Kentucky Revised Statutes 500.080 – Definitions for Kentucky Penal Code That label is what pulls them into the state’s concealed carry rules, location bans, and enhanced penalties.
Keeping Them at Home
No Kentucky statute bans possession. KRS 527.020 expressly exempts anyone carrying a concealed deadly weapon on property they own or lease, or on property owned by a spouse, parent, grandparent, or child.2Justia. Kentucky Code 527.020 – Carrying Concealed Deadly Weapon Storing them in your house, on your land, or at a business you own is not a crime. The rules tighten once you leave your own property.
Carrying Brass Knuckles
Concealed Carry at 21 and Older
Kentucky is a permitless carry state. Anyone 21 or older who can lawfully possess a firearm may carry a concealed deadly weapon without a license, and the Kentucky State Police confirm this extends to “any deadly weapon, as defined by KRS 500.080.”3Kentucky State Police. CCDW FAQs Brass knuckles are covered.
Under 21
People under 21 cannot carry a concealed deadly weapon in Kentucky. The State Police put it directly: someone under 21 “may be eligible to possess a firearm, but are not allowed to carry the firearm (or other deadly weapon) concealed in Kentucky.”4Kentucky State Police. Permitless Carry Concealed brass knuckles carried off your own property before that age is a criminal offense.
Open Carry
Kentucky has no general open-carry ban for deadly weapons. According to the State Police, the only open-carry statutes involve weapons on school property and loaded firearms in businesses selling alcohol by the drink.3Kentucky State Police. CCDW FAQs The alcohol restriction applies to loaded firearms, not to brass knuckles, so the school ban is the main open-carry rule that reaches them.
The Vehicle Exception
A deadly weapon stored in any factory-installed enclosed compartment of a vehicle is not considered “concealed on or about the person.” The glove box, center console, and seat pockets all qualify, whether locked or not.2Justia. Kentucky Code 527.020 – Carrying Concealed Deadly Weapon Someone under 21 keeping brass knuckles in the glove box is not carrying them concealed under the statute. The exception only covers factory-installed compartments, so an aftermarket lockbox may not qualify.
Where You Cannot Take Them
Even adults who can legally carry face location restrictions, and several carry felony penalties.
Schools
KRS 527.070 makes it illegal to possess any deadly weapon on school property, whether openly or concealed. The ban covers school buildings, buses, campuses, athletic fields, and recreation areas of any public or private school. A violation is a Class D felony, punishable by one to five years in prison and a fine of up to $10,000. No prior conviction is needed for the felony charge, which catches some people off guard.
Jails and Prisons
KRS 527.020 prohibits carrying a concealed deadly weapon in a detention facility without permission from the warden, jailer, or person in charge. The statute defines “detention facility” to exclude courtrooms and premises used by the Court of Justice, though courthouses often restrict weapons through other provisions.2Justia. Kentucky Code 527.020 – Carrying Concealed Deadly Weapon
Government Buildings
KRS 237.115 lets state, city, county, and urban-county governments prohibit or limit concealed deadly weapons in buildings they own, lease, or control. Any restricted area must be posted at the entrance.5Kentucky Legislative Research Commission. Kentucky Revised Statutes 237.115 – Construction of KRS 237.110 That is the mechanism police stations, city halls, and courthouses use to ban weapons on site.
Federal Buildings
Federal law adds a separate layer. Under 18 U.S.C. ยง 930, knowingly possessing a dangerous weapon in a federal facility is a federal crime regardless of state law, and brass knuckles fit the statute’s definition of “dangerous weapon.” Basic possession carries up to one year in prison; possession with intent to commit another crime, up to five years; possession in a federal courthouse, up to two years.6Office of the Law Revision Counsel. 18 USC 930 – Possession of Firearms and Dangerous Weapons in Federal Facilities
Penalties for Illegal Carry
A first offense of carrying concealed brass knuckles unlawfully, with no relevant prior felony, is a Class A misdemeanor. That means up to 12 months in jail7Justia. Kentucky Code 532.090 – Sentence of Imprisonment for Misdemeanor and a fine of up to $500.
If you have a prior felony conviction in which a deadly weapon was possessed, used, or displayed, the charge becomes a Class D felony.2Justia. Kentucky Code 527.020 – Carrying Concealed Deadly Weapon A Class D felony carries one to five years in prison and a mandatory fine between $1,000 and $10,000.8Kentucky Legislative Research Commission. Kentucky Revised Statutes 534.030 – Fines for Felonies The prior does not have to involve brass knuckles; any felony where a deadly weapon was part of the offense triggers the enhancement.
Carrying brass knuckles onto school property is charged separately under KRS 527.070 as a Class D felony from the start, with the same one-to-five-year range and up to $10,000 in fines.
Self-Defense Considerations
Kentucky’s self-defense law is favorable to the defender. Under KRS 503.050, you may use deadly physical force when you reasonably believe it’s necessary to protect against death, serious physical injury, kidnapping, or a felony involving force, with no duty to retreat.9Kentucky Legislative Research Commission. Kentucky Revised Statutes 503.050 – Use of Physical Force in Self-Protection
Brass knuckles are contact weapons, so any situation where you can use them is close enough that the line between justified force and excessive force gets blurry fast. Because they are classified as a deadly weapon, striking someone during a fistfight that started as a verbal argument can turn an assault charge into assault with a deadly weapon. The legal right to carry them is not a legal right to use them in every confrontation.
