Brass knuckles are not illegal to own in Ohio, but carrying them concealed on your body, in your bag, or within easy reach is a crime. Ohio treats brass knuckles as a “deadly weapon,” and a first offense is a first-degree misdemeanor punishable by up to 180 days in jail and a $1,000 fine. A prior weapons or violence conviction turns the same conduct into a fourth-degree felony.
Why Brass Knuckles Count as a Deadly Weapon
Ohio Revised Code Section 2923.11 defines a deadly weapon as any instrument capable of inflicting death that is either designed as a weapon or possessed and carried as one.1Ohio Legislative Service Commission. Ohio Revised Code Section 2923.11 – Weapons Control Definitions The statute doesn’t name brass knuckles, but courts consistently place them in the category because they exist to concentrate the force of a punch and can cause lethal injury.
Possession alone at home is not the problem. Ohio amended Section 2923.20 in April 2021 and removed brass knuckles from the list of items whose manufacture, sale, and furnishing were specifically prohibited. Buying them, selling them, and keeping them in your house are no longer restricted by that statute. The criminal exposure begins when you take them out in public.
Concealed Carry Is the Offense
Ohio Revised Code Section 2923.12 makes it illegal to knowingly carry a deadly weapon concealed on your person or concealed ready at hand.2Ohio Legislative Service Commission. Ohio Code 2923.12 – Carrying Concealed Weapons A pocket, waistband, purse, or backpack all count as concealed on your person. “Concealed ready at hand” reaches beyond your body to anything stashed nearby for quick access.
An Ohio Concealed Handgun License does not help. The license covers handguns and nothing else. It gives you no legal cover for carrying brass knuckles or any other non-firearm deadly weapon.2Ohio Legislative Service Commission. Ohio Code 2923.12 – Carrying Concealed Weapons
Brass Knuckles in Your Vehicle
The glove box, center console, and area under a seat are all places a court can treat as “concealed ready at hand.” Ohio law does contain a vehicle exception, but it applies only to firearms.2Ohio Legislative Service Commission. Ohio Code 2923.12 – Carrying Concealed Weapons Brass knuckles get no such carve-out. If a traffic stop turns them up in a reachable spot inside your car, expect a concealed weapons charge.
Courthouses and School Zones Carry Heavier Penalties
Two locations raise the stakes well above the baseline misdemeanor.
Under Ohio Revised Code Section 2923.123, knowingly bringing a deadly weapon into a courthouse or any building containing a courtroom is a separate offense, and possessing one inside such a building is also prohibited.3Ohio Legislative Service Commission. Ohio Revised Code 2923.123 – Illegal Conveyance of Deadly Weapon or Dangerous Ordnance Into Courthouse Certain law enforcement exemptions can be overridden by local court rules.
Under Section 2923.122, possessing a deadly weapon in a school safety zone is a fifth-degree felony. The zone covers the school building, the surrounding premises, school-sponsored activities, and school buses.4Ohio Legislative Service Commission. Ohio Revised Code Section 2923.122 – Illegal Conveyance or Possession of Deadly Weapon in School Safety Zone A prior conviction under the same section bumps the charge to a fourth-degree felony, and a conviction can trigger a mandatory additional two-year prison term served before the sentence for the underlying offense.
Penalties
The base charge is a first-degree misdemeanor, punishable by up to 180 days in jail and a fine of up to $1,000.2Ohio Legislative Service Commission. Ohio Code 2923.12 – Carrying Concealed Weapons5Ohio Legislative Service Commission. Ohio Revised Code Section 2929.28 – Financial Sanctions, Misdemeanor
If you have a prior conviction under the concealed-carry statute or any prior offense of violence, the same conduct becomes a fourth-degree felony carrying six to eighteen months in prison and a fine of up to $5,000.2Ohio Legislative Service Commission. Ohio Code 2923.12 – Carrying Concealed Weapons6Ohio Legislative Service Commission. Ohio Revised Code Section 2929.18 – Financial Sanctions, Felony
The jump to felony matters beyond the sentence. A felony conviction creates a weapons disability that bars you from legally acquiring, carrying, or using firearms. You can petition the court of common pleas for relief, but the court isn’t required to grant it, and any qualifying offense picked up afterward automatically voids the relief.7Ohio Legislative Service Commission. Ohio Revised Code 2923.14 – Relief From Weapons Disability
Self-Defense Does Not Fix the Carry Charge
Ohio recognizes self-defense, and since April 2021 there is no duty to retreat before using force in a place you have a legal right to be.8Ohio Legislative Service Commission. Ohio Revised Code 2901.09 – No Duty to Retreat in Residence or Vehicle Once you raise self-defense at trial, the prosecution must disprove it beyond a reasonable doubt.9Ohio Legislative Service Commission. Ohio Revised Code Section 2901.05 – Burden of Proof, Reasonable Doubt
That defense only reaches the use of force. It does nothing about the separate crime of carrying a concealed deadly weapon. A jury can acquit you of assault on self-defense grounds and still convict you for having the brass knuckles hidden on you. Anyone treating brass knuckles as a personal protection tool is building a criminal charge into the plan from the start.
Plastic, Carbon Fiber, and “Novelty” Knuckles
Material doesn’t decide the question. Ohio’s deadly weapon test asks whether an item is capable of inflicting death and whether it was designed or carried as a weapon.1Ohio Legislative Service Commission. Ohio Revised Code Section 2923.11 – Weapons Control Definitions A plastic, resin, or carbon fiber piece shaped to fit over the fingers and concentrate a punch meets both parts. Labels like “paperweight” or “novelty” don’t change the analysis if a prosecutor can show the item was carried as a weapon.
