Florida Knife Laws Explained

Florida has one of the most vague concealed carry knife laws of all 50 states. This means that you must read case precedence to see what is legal and what is not. Don’t worry, we did all the hard work for you. Below is what Florida law says about knives in everyday English. It includes excerpts from the law as well as case decisions.

What is Legal to Own

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

The law does not limit individuals from owning, selling, or buying any knife except for ballistic knives.

Limits on Carry

  • You can open carry any knife.
  • Box cutters, multi-tools, and other work knives are legal to carry concealed.
  • In most cases, conceal carry of a common pocket knife with a blade of less than 4 inches is legal.
  • Anything outside of this has not been expressly banned or allowed.

What the Law Says

Fla. Stat. § 790.01 (2012)

§ 790.01.  Carrying concealed weapons

[A] person who carries a concealed weapon […] on or about his or her person commits a misdemeanor of the first degree, punishable as provided in s. 775.082 or s. 775.083.

“Concealed weapon” means any dirk, metallic knuckles, slungshot, billie, tear gas gun, chemical weapon or device, or other deadly weapon carried on or about a person in such a manner as to conceal the weapon from the ordinary sight of another person.

“Weapon” means any dirk, knife, metallic knuckles, slungshot, billie, tear gas gun, chemical weapon or device, or other deadly weapon except a firearm or a common pocketknife, plastic knife, or blunt-bladed table knife.

It is a crime to carry a concealed weapon. Concealed weapon means any deadly weapon that is outside of sight of others. Courts have found that deadly weapons are weapons that can cause death or grave bodily harm. So, what kinds of knives counts as deadly weapons? What is a “common pocket knife? Well, the law doesn’t say so it is up to the courts to determine.

The case of Porter vs. State in 2001 found that a pocket knife is a “common pocket knife” only if the blade is less than 4 inches in length and the knife is in the closed position. Police found Porter with a 4 inch folder knife in the open position in her purse. She was arrested for possession of a weapon by a convicted felon and found guilty. She appealed stating that the knife is a common pocket knife but the appeal court turned down her appeal. This means that, if a pocket knife is over 4 inches and in the open position, it is a weapon and excluded from being a “common pocket knife.”

However, if the pocket knife has too many features, it might not be a “common pocket knife.” The case of F.R. vs State in 2012 found that 3 inch pocket knife with serrations, a notch grip, hilt guard, and locking mechanism does not count as a “common pocket knife.” If his knife did not have serrations, a notch grip, hilt guard, and locking mechanism, it might of been a “common pocket knife.”

If the knife was designed for utility and not harm, it is not a deadly weapon. In the case of Holley v. State in 2004, it was found that a box cutter or razor knife does not qualify as a deadly weapon because it was designed for utility not bodily harm.

In addition to the physical characteristics of the knife, the courts also decided that how the knife was used and handled needs to be taken into account as well. In the case of Mims v. State, Mims was found guilty of carrying a concealed weapon for having a pocket knife in his pocket during a robbery.

These cases still do not present that clear of a picture of what type of knife is a weapon and the case of Bell vs. State in 1996 found that it is up to the jury to decide if a knife is a deadly weapon given the definition of a deadly weapon, the knife, and how the knife was used into consideration. Judges can not make the decision.

The case of Hardy vs. State in 1992 found that a knife inside of a vehicle is not concealed if the knife and sheath is visible from the outside. Having a knife in the vehicle usually counts as having a concealed weapon but, if it is visible threw the windows, it is not concealed.

What does this all mean? It means that you should stick to a plain 4 inch pocket knife, multi-tool, or box cutter. Any other type of knife can be illegal.

Ballistic Knife Ban

Fla. Stat. § 790.225 (2012)

§ 790.225.  Ballistic self-propelled knives; unlawful to manufacture, sell, or possess; forfeiture; penalty

(1) It is unlawful for any person to manufacture, display, sell, own, possess, or use a ballistic self-propelled knife which is a device that propels a knifelike blade as a projectile and which physically separates the blade from the device by means of a coil spring, elastic material, or compressed gas. A ballistic self-propelled knife is declared to be a dangerous or deadly weapon and a contraband item. It shall be subject to seizure and shall be disposed of as provided in s. 790.08(1) and (6).

Ballistic knives are also illegal under federal law so it is best to stay away from them.

Conclusion on Florida Knife Laws

For the most part, Florida knife laws are easy. You can own any knife as long as it is not a ballistic knife and, if you keep your knives at home, you should be fine. You can also open carry any knife you want. You can conceal carry any box cutter, multi-tool, or 4 inch pocket knife. Conceal carry of any other type of knife can or can not be considered carrying a concealed weapon so watch out.

There are also local laws outside of this so look up the laws in your city as well. Most cities in Florida have clearer guidelines on what is legal and illegal than the state law.

    How does this impact people who wear a knife as part of a regalia, national costume, etc?
    For example.. I’m Scots, and, if I dress “full formal”, I wear a short, non- folding blade tucked in my sock. Traditionally, you put it there so it’s on display, as a courtesy… But I was told I needed a CC permit to wear it in a public park….

  • Robert

    I would like to know the specifics for Kabar TDI knife. It is solid blade knife approx 2-3″ blade that is carried in a sheath mounted on your belt , hung around the neck or around the ankle.

  • Ben

    I usually have a knife I’ve measured to be 3.5 in. long with a seatbelt cutter and a glass breaking point on the end. When I’m in my car I have it in either the cup holder between the two front seats, in the hand grip on the door, or the area at the bottom where napkins or other small things can be kept for organizational purposes. I’m not positive that my methods are legal so where could/would I go to confirm or deny this?

    • Michael Dunning

      Hi I am a police officer and I just want to let you know that yes if your knife is in the cup holder you are fine. We as officers are able to see it through your window. But if you do get pulled over what you need to do is as soon as you roll down your window put both hands on your steering wheel and tell the officer you have a knife in the cup holder and ask him/her how they would like to proceed
