Knife Laws By State 2021

Certain knives are used mostly for protection, for hunting, and for handyman work.

Owning a knife is not illegal within the United States. However, each state has different regulations on the types of knives that people can have. They also explain how legal knives should be carried and used.

California

In California, the knife laws are considered some of the strictest in the country. Throughout the state, it is considered legal to purchase and carry any knife that is under two inches in length. Some other knives that are legal within the state include:

  • Bowie knives
  • Large knives (no restriction in size)

California also has a list of restricted knives that people cannot possess, buy, or use. These knives are typically above two inches in length and include:

  • Knives that cannot be detected by metal detectors
  • Misleading knives (cane knives, zobi-tsues, belt knives, pen knives, air gauge knives, and lipstick knives)
  • Dirks, stilettos, and daggers
  • Ballistic (throwing) knives

Texas

In Texas, there are two different types of knife types distinguished by the length of the blade: a simple ‘knife’ or a ‘location restricted knife.’ A knife that has a blade of 5½ inches or less is considered as the regular ‘knife’ term. A ‘location restricted knife’ is a knife with a blade above 5½ inches. As for legality concerns, people in Texas can own, carry, and purchase the following types of knives:

  • Throwing stars or any type of throwing knife
  • Dirks, daggers, stilettos, and other stabbing knives
  • Bowie knives
  • Swords or spears
  • Switchblade knives
  • Pocketknives
  • Balisong, or butterfly knife

As for knives that are illegal, any ‘location restricted knives’ should not be possessed or carried by people within the state.

Florida

In Florida, the law allows for people to bear certain weapons, including knives, to protect themselves from any danger they may face. However, there are certain limitations to the types of knives that can be owned by people in the state. For instance, the knives that people in Florida are freely able to own are:

  • Balisong knives
  • Belt knives, cane knives, and other disguised knives.
  • Bowie knives and other large knives
  • Throwing stars and throwing knives
  • Undetectable knives (knives that will not set off metal detectors)

Despite this freedom to own, there are specific limitations to what kind of knives people can carry with them. The knives that are acceptable for concealed carrying include:

  • Box cutters, multi-tools, and other work knives
  • Common pocketknives with a blade less than 4 inches (in some cases)
  • Knives with a blade over 4 inches for people with permits

There is one type of knife that is illegal to have throughout the state, though: ballistic knives. No one should carry, purchase, or own one of these knives or there will be serious consequences.

Ohio

In Ohio, it is legal to own any type of knife. Instead of basing their laws off knife lengths, they base theirs on what is considered a “deadly weapon. By definition, a deadly weapon in this state is “any instrument, device, or thing capable of inflicting death, and designed or specially adapted for use as a weapon, or possessed, carried, or used as a weapon.” In this state, people are allowed to own and carry the following types of knives:

  • Switchblades or gravity knives
  • Balisong (butterfly) knives and Balisong trainers
  • Ballistic knives
  • Dirks, daggers, or other stabbing knives
  • Bowie knives
  • Stilettos

There is only one type of limitation to concealed carry within the state: any knife that is considered a “dangerous ordnance” cannot be concealed. This statute makes it illegal to conceal carry any dangerous knife out there, which can include all the knives listed above.

Illinois

In Illinois, people have the right to carry specific knives for their own protection and more. The only limit that they explicitly express is that the person carrying the knife cannot use it to harm anyone (without good reason) or to break the law. Knives that people can be owned within this state include:

  • Balisong knives
  • Disguised knives (cane knives, belt knives, and lipstick knives)

Michigan

In Michigan, people can carry certain knives for many reasons. If people are not using certain knives for malicious intent, they can freely carry them openly and through concealment.

New York

In New York, knife laws are more confusing since knives can be considered dangerous even if the person owning them has no criminal intent in mind.

  • Hunting knives

The following knives are illegal for any New York resident to own:
