Folding Knife Laws: State-by-State Guide

By Michael JacksonApril 1, 2026

Folding knives, with their convenient and compact design, have become a staple in many people's everyday carry. However, the legality of carrying and using these knives varies greatly from one jurisdiction to another. Understanding your local laws is crucial to ensure you're in compliance and avoid potential legal issues. Let's delve into the intricacies of folding knife laws across different regions.

Before we dive into specific laws, it's essential to understand the fundamental distinction between fixed-blade and folding knives. Fixed-blade knives have a blade that is permanently attached to the handle, while folding knives have a blade that folds into the handle when not in use. This difference is often the basis for legal distinctions.

United States Folding Knife Laws

The United States has a complex patchwork of knife laws, with significant variations at the federal, state, and local levels. Here, we'll provide an overview of some key aspects, focusing on folding knives.

At the federal level, the Switchblade Knife Act of 1952 prohibits the interstate commerce of switchblade knives, which are defined as knives with a blade that opens automatically by hand pressure applied to a button or other device. However, this law does not prohibit the possession or carrying of switchblades within a single state.

State Laws

State laws on folding knives vary widely. Some states, like California and New York, have strict restrictions on switchblades and other automatic knives. In California, for instance, it's illegal to manufacture, import, sell, or possess switchblades without a valid reason, such as being a law enforcement officer or a collector.

Other states, like Texas and Florida, have more lenient laws. Texas allows the carrying of folding knives with a blade length of 5.5 inches or less, while Florida has no specific restrictions on folding knives, only on switchblades and dirks (knives with a dagger-like blade).

Local Ordinances

In addition to state laws, many cities and counties have their own knife ordinances. For example, Chicago has a ban on carrying any knife with a blade over 2.5 inches, while New York City prohibits the carrying of gravity knives, which are defined as knives that open by the force of gravity or the application of centrifugal force.

It's crucial to research and understand the specific laws in your city or county, as they can often be more restrictive than state laws.

International Folding Knife Laws

International laws on folding knives also vary significantly. In the United Kingdom, for instance, it's illegal to carry a knife in public without a valid reason, and any knife with a locking blade is considered a prohibited weapon. In contrast, many European countries have more lenient laws, with some allowing the carrying of folding knives with blade lengths up to 12 centimeters (about 4.7 inches).

In Australia, the laws on folding knives vary by state. Some states, like Victoria, have restrictions on the carrying of knives with blades over 100mm (about 3.9 inches), while others, like Western Australia, have no restrictions on folding knives.

Canada

Canada's Criminal Code prohibits the carrying of concealed weapons, which can include folding knives. However, the code also provides exemptions for knives carried for legitimate purposes, such as hunting, fishing, or camping. The specific laws can vary by province, with some provinces having more restrictive laws than others.
