Understanding the Legal Landscape of Pocket Knives in Ohio

Ownership: There are no state restrictions on owning pocket knives, including folding knives, automatic knives, or other common varieties.

Open Carry: Any type of pocket knife may be openly carried without significant legal risk, provided it is not displayed or used in a threatening manner.

Concealed Carry: Senate Bill 140, effective since April 2021, dramatically relaxed prior restrictions. Concealed carry of pocket knives is legal, unless the knife is used or intended to be used as a weapon.

Deadly Weapon: In Ohio, a pocket knife is not automatically considered a “deadly weapon.” However, if you use or brandish your knife as a weapon, it can be classified as such, resulting in criminal liability.

Intent Matters: Simply carrying a concealed pocket knife is not a crime unless you’re using it for harm or have the intention to use it as a weapon.

Blade Length: Ohio state law does not specify a maximum blade length for pocket knives. However, experts recommend keeping blades under 4 inches to avoid subjective interpretation by law enforcement.

Minimum Age: Generally, a person must be 21 to carry a knife, but there are exceptions, particularly for basic pocket knives used by minors for utility purposes.

Schools and School Zones: Carrying knives of any kind is forbidden on school property.

Courthouses and Government Buildings: Similar restrictions apply, regardless of knife type.

Local Ordinances: While recent state reforms preempt many local laws, some municipalities may attempt to enforce stricter rules. Always check local regulations where you live or travel.

Always carry pocket knives for work, utility, or lawful purposes—never for use as a weapon.

If questioned by law enforcement, calmly explain the utilitarian purpose of your knife.

When in doubt about local rules, check with municipal authorities or legal counsel.

Using your knife as a weapon—especially concealed—can result in both criminal charges and civil liability.
