If you live in or plan to visit Ohio and carry a knife—whether for work, outdoor activities, or self-defense—it’s very important to understand the state’s knife laws. Ohio has specific rules on what knives are allowed, how they can be carried, and under what conditions they become illegal.
This guide breaks down Ohio’s knife laws in simple terms so you can stay informed and avoid trouble with the law.
Basic Overview of Ohio Knife Laws
According to Ohio Revised Code, a knife may be legally carried—but under certain conditions.
In general:
- Open carry of knives is legal in Ohio.
- Concealed carry is more regulated, especially for knives seen as “deadly weapons.”
A knife may be considered a deadly weapon if:
- It is specially designed for combat or violence (like ballistic knives).
- It is used or intended to be used to cause harm.
Even simple pocket knives could be treated as deadly weapons if used in a threatening way.
Open Carry vs Concealed Carry in Ohio
The difference between open carry and concealed carry is key.
- Open Carry: You can legally carry most knives openly in Ohio. There’s no law stopping you from wearing a knife on your belt or carrying it visibly.
- Concealed Carry: Things change when a knife is hidden from view. If the knife is considered dangerous or if you’re carrying it for self-defense without a proper reason, it may be illegal to carry it concealed.
Police may judge differently based on the situation, so being cautious is smart.
Types of Knives Regulated in Ohio
Not all knives are treated the same. Here’s how Ohio handles specific knife types:
Legal (with some conditions)
- Folding knives (like pocket knives)
- Fixed blade knives
- Automatic/switchblade knives – These are now legal after Senate Bill 140, but concealed carry still has conditions.
Still Restricted
- Ballistic knives
- Gravity knives – These remain under tight control due to their easy deployment mechanism.
What Did Senate Bill 140 Change?
Senate Bill 140, which took effect in April 2021, changed Ohio’s knife laws significantly.
Before 2021:
- Knives like switchblades and butterfly knives were banned for manufacture and sale.
After SB 140:
- These knives are now legal to own, sell, and carry, especially for utility purposes.
- However, concealed carry of any knife is still judged based on intent and context.
This law brings Ohio in line with many other states that have relaxed rules on common knife types.
Legal Consequences of Breaking the Law
If you’re caught carrying an illegal knife or using any knife to threaten or harm someone, it becomes a serious legal matter.
- A knife can be classified as a deadly weapon.
- You could face fines, criminal charges, or even jail time depending on the case.
That’s why it’s important to:
- Know what you’re carrying.
- Understand how and when to carry it legally.
- Never use a knife in a threatening or dangerous manner.
Ohio knife laws have become more relaxed in recent years, especially with the passing of Senate Bill 140. Still, it’s crucial to stay informed and carry your knife in a way that keeps you safe and on the right side of the law.
Whether you’re a knife collector, a worker, or someone who carries a knife for personal safety, knowing the rules about open vs concealed carry and the types of knives allowed will help you avoid legal trouble and stay protected.
