These knives have applications for collectors, hobbyists, sports enthusiasts, and anyone looking for a tool for self-defense. If you’re a knife lover, and you want to invest in a well-crafted automatic knife, you’re probably wondering, “Are switchblades illegal?”

These knives are some of the more controversial blades available, with varying levels of legality across the United States. If you’re confused by your state’s knife laws, you’re not alone! Knife legislature is both confusing and ever-changing. In this article we’ll discuss the legality of different kinds of knives across the United States, so read on to learn more!

The Different Kinds of Knives

Knife enthusiasts will already be familiar with many different kinds of knives. However, it’s important to recognize the specific distinctions between fixed, folding, and switchblade knives because carry and conceal laws vary based on these three types. 

Fixed Blade

A fixed blade knife is a knife that has no moving parts. The blade does not fold or slide. You can cover the blade by placing it in a sheath.

Fixed blades are often very strong because the metal of the blade runs down the length of the handle and creates a spine of stability through the knife. 

Bowie knives and daggers are considered fixed blades, as all these knives are entirely immobile. However, due to their nature as weapons, these blades will sometimes have different carry restrictions. 

Folding Blade

Folding blades are so named because the blade folds into the handle for storage. A great example is a simple pocket knife.

To open a pocket knife, you must manually pull the blade out, and push it back inside to close it. The blade is mobile, but not automatic. 

Switchblade

The Federal Switchblade Act of 1958 defined switchblades as any knife that has a blade that opens automatically. The act prohibits the importation and interstate commerce of all types of switchblades. 

However, the Federal Switchblade Act has no restriction on purchasing or carrying switchblade knives. These regulations vary state by state or even county by county. 

Gravity blades have a button or trigger that unlocks the blade so gravity can pull the blade from the handle. Other switchblades have a trigger or button in the handle that springs the blade out. These are known as OTF knives, where the blade is sprung “out the front.” 

Knife enthusiasts use them either in trade work or carry them as tools for self-defense. Knife collectors also keep them as curios, because many switchblades feature beautiful craftsmanship and ingenuity.

Knife Laws

Knife laws have three different categories: ownership law, carry law, and conceal law. Each of these laws varies depending on the state and the type of knife. 

  • Ownership law is the basic regulation of whether or not it’s legal to own a type of knife
  • Carry law is the regulation of whether or not it’s legal to carry a knife on your person outside of the house 
  • Conceal law is the regulation of whether or not you can conceal a knife on your person outside of the house

Where Are Switchblades Illegal? 

Regardless of the state, all knives are prohibited in schools, courts, federal buildings, and other state and local government buildings. Also, it is illegal to carry knives at airports and on planes.

The remaining restrictions vary state by state. Some states still define knives as a deadly weapon, and generally, these states have stricter regulations. Other states made explicit commitments to defending the right to bear arms and allow you to carry and conceal more types of knives.

Let’s get into the nitty-gritty.
