Is it legal to possess a pocket knife in Ohio?

Columbus, OH – Ohio has recently made significant changes to its knife laws, aligning with the growing trend of loosening regulations on bladed instruments. These updates have important implications for both residents and visitors, as they provide clearer and more consistent guidelines in what used to be a complex legal environment.

Recent Legislative Developments

Governor Mike DeWine signed Senate Bill 140 on January 11, 2021, which brought about a significant change in Ohio’s knife regulations. This new legislation, effective from April 12, 2021, repealed the ban on the manufacture and sale of “switchblade,” “spring blade,” and “gravity” knives. As a result, Ohio expanded the range of knives that can be legally sold and owned within the state, while also creating new opportunities for businesses involved in knife manufacturing.

SB 140 made a significant change in its definition. Now, a knife, razor, or cutting instrument is only considered a “deadly weapon” or “weapon” if it is used as one. This means that simply possessing a knife no longer automatically categorizes it as a weapon. This modification addresses the previous legal ambiguity surrounding the possession of knives.

Statewide Preemption and Uniformity

On September 13, 2022, a significant milestone was achieved with the passing of the Knife Rights’ Ohio Knife Law Preemption bill. This legislation sought to address the issue of inconsistent knife laws that differed greatly among various municipalities in Ohio. Certain cities, such as Cleveland and Rocky River, had strict local ordinances pertaining to knives, which posed potential legal complications for both residents and visitors who were unaware of these variations. However, with the implementation of the preemption bill, these localized regulations are now superseded, ensuring a consistent application of state-level knife regulations throughout Ohio.

Implications for Knife Carrying and Use

Ohio residents have the freedom to carry a range of knives, including switchblades, gravity knives, and butterfly knives, which were previously restricted. The legality of carrying these knives is based on their intended use. As long as the knife is not used as a weapon, it is legal to possess and carry, whether openly or concealed.


Location-Specific Restrictions

Although there have been some relaxations in the rules, certain restrictions related to specific locations still exist. For example, it is considered unlawful to have a “deadly weapon” as outlined in § 2923.11 (A) within areas designated as “school safety zones” or “courthouses.” This includes any knife that meets the criteria of a deadly weapon in these particular settings. Therefore, it is important to exercise caution when carrying knives in or around schools and court facilities.

Law Enforcement and Military Exceptions

Law enforcement officers and military personnel in Ohio have the permission to carry concealed knives while on duty, acknowledging the unique requirements and responsibilities that come with their professions. Certain exemptions also allow them to carry concealed knives when they are off-duty.


Ohio has recently made legislative changes to its knife laws, which signals a noteworthy step towards creating a more knife-friendly environment. This shift aims to strike a balance between upholding individual rights and ensuring public safety. It highlights the changing perspectives on knife ownership and usage in the United States, aligning with broader trends in criminal justice reform and the protection of individual liberties.
