Why Understanding Knife Laws Matters

If you carry an EDC knife, it’s important to know and follow the laws in your area. Knife regulations in the United States are not the same everywhere, and what is acceptable in one place may be restricted in another.

This article doesn’t list laws or attempt to cover every situation. Instead, it explains the types of rules that often exist so you can make sure you’re informed before you carry.

1. Laws About Blade Size

Many areas set limits on how large a knife blade can be. Because these rules can vary widely, it’s essential to know how your city, county, or state defines and measures blade length.

2. Rules for Different Types of Knives

Some places treat certain types of knives—such as folding knives, fixed blades, or knives with assisted-opening mechanisms—differently. These differences can affect where and how you’re allowed to carry.

3. Concealed Carry and Open Carry Restrictions

Carrying a knife where it can’t be easily seen (concealed) is sometimes treated differently than carrying it openly. Be sure you understand the expectations in your area.

4. Prohibited Locations

Even if a knife is legal to carry, there are usually certain places where knives are never allowed. Always be aware of where you are and follow any posted regulations.

Regulations can change from one town or county to the next. It’s important not to assume that laws are the same everywhere, even if you are in the same state.

6. Traveling with an EDC Knife

If you’re going somewhere new, take the time to learn what’s allowed at your destination. Laws can change dramatically once you cross into another city or state, and travel hubs like airports often have their own strict regulations.
