Know Your Knife Laws

In an era where virtually everything is a crime, it is important to know the law. This is especially true with regard to knife laws which vary tremendously. They not only vary state to state but from municipality to municipality as there are few state preemption laws with regard to knifes.

The infographic below from is a good start and presents the info in an easily understood form. I'd also suggest becoming a member of Knife Rights as they are taking the fight for knife rights to both the court house and the state house.

One example of how fast knife laws are changing is the info below on which states make automatic or switchblade knives illegal. It lists both Kansas and Missouri as prohibiting them. Thanks to Knife Rights, this was recently changed and they are now legal there.

Infographic removed due to inaccuracies.

If you'd still like to see it, go to See comments below as to some of the inaccuracies. Alternatively, go to Liston's website here.

  1. The switchblade law in Missouri was changed back in 2012. No longer illegal.

    1. Ditto the switchblade law in Florida, amended in 2005.

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

      The pertinent part is "(2) This section shall not apply to:
      (a) Any device from which a knifelike blade opens, where such blade remains physically integrated with the device when open."


    2. Correction: amended in 2003

  2. These guys are clowns. All three graphics are wrong about NC, the last one hilariously so. It is not illegal to possess a switchblade, ballistic knife, or in fact, any kind of knife at all. It's not even illegal to carry them. It's only illegal to carry them concealed. As for the last graphic, the law that bans concealed weapons says very specifically

    § 14-269. Carrying concealed weapons.
    (d) This section does not apply to an ordinary pocket knife carried in a closed position. As used in this section, "ordinary pocket knife" means a small knife, designed for carrying in a pocket or purse, that has its cutting edge and point entirely enclosed by its handle, and that may not be opened by a throwing, explosive, or spring action.

    KnifeUp needs to do better research. Apparently their current research consists of "make shit up."

  3. Yep, appears they did NO research on Massachusetts. We have the 4" law for carrying a knife, also ballistic knives are illegal here. I don't know if it counts, you can OWN a switchblade, but you can't carry it outside your home.

    Yeah everybody should take these maps with a grain of salt.

  4. As of Sept 2013 gravity knives and switchblades, the only knives ever criminalized in Alaska statute in any way and 2 of only three weapons called out by name or description (the remaining one being "metal knuckles"), are now perfectly legal to manufacture, possess, and carry openly or concealed for those over 16 years of age. We also have knife preemption so local entities can no longer restrict knife possession, sale, or carry beyond state law.

    Knives in general in schools are still subject to some unchanged restrictions, primarily involving students.

  5. We should know our rights and follows the rules regarding to uses and carry of knife weapons where we live in .Some states which consider it is legal, and some states illegal. So better in this era of crime we should know about that.

  6. Michigan laws are more grey then anything for sure, and I know there has been a new bill presented in 2013. So I have been looking to see if it has passed. I have never been hassled when wearing my hunting knife or my filet knife when outdoors. My folding knife is always in a case on my side and has been 4 inches since the day I got it, when I was 12 years old (47 now). It's gone through 8 cases and the blade is now probably legal but the laws in Michigan are very grey when it comes to knives. It's funny to I wore it to school never got in trouble. It was always on my belt, every teacher knew I had it. But man now a days!!! YIKES!!!.. anyways I'll shut up now.

  7. Our nation recognize each of our protection under the law along with employs the policies with regards to for you to employs along with hold involving cutlery tools wherever many of us are in. A number of claims which in turn contemplate it can be authorized, and a few claims outlawed. Consequently greater within this years involving criminal offenses our nation be familiar with that will.
