Connecticut Knife Law – The Complete Guide (In Plain English)

Despite how short and liberal Connecticut Knife Laws are, they leave a fair amount of latitude and confusion about the specific types of knives that can be owned or carried in the state.

So let’s take a deep dive and see if we can make things a bit more black and white.

Quick Notes Version Of Connecticut Law

Legal Knives

In general, Connecticut has very few laws regarding what types of knives can be owned.

Legal knives include:

  • Balisong/butterfly knives
  • Switchblades
  • Gravity knives
  • Dirks, stilettos, daggers, and push knives
  • Bowie knives (or other large fixed blade or folding knives)
  • Disguised knives eg. belt buckle knives, cane knives, lipstick knives, etc.

Long story short, basically any type of knife that you can think of is legal to own if all you’re going to do with it is have it in your home. There are, however, laws that make certain knives illegal for carrying in public.

Illegal Knives

Connecticut knife law has several restrictions about the length of knife that can be carried.

These laws apply whether you are carrying the knife openly or concealing it. In other words, do not leave your property with the following knives:

  • Automatica knives (including switchblades) over 1.5″
  • Stilettos (OTF knives)
  • Knives 4″ or over with a single cutting edge (meaning a 4.00″ blade is illegal)
  • Double edge knives over 1.5″

Note that lengths refer to the EDGED PORTION of the blade, not the length of the overall knife or blade. Blade length is supposed to be measured using the AKTI Protocol (with a 1/8″ variance allowed) but law enforcement is not required to observe the variance.

Other Regulations To Be Aware Of

Because the penalty for breaking many of Connecticut’s knife laws is a felony (meaning a fine and jail time) you’ll want to be aware of a few more things so you can keep your nose clean:

  • Transport of “Illegal Knives” Knives of the “Illegal” list that are techincally legal to own can only be carried or used on private land with the permission of the land owner. If you are going camping on private land, any knives that are not legal for carry must be transported in the trunkn where they cannot be accessed.
  • Age limit. There is no age limit for owning or carrying knives in the state of Connecticut. However, most stores will not sell a knife to a person under 16 years old without a parent present.
  • “Lisence” to carry. Knives with a blade longer than 4″ can be carried if you have a fishing or hunting lisence and are activity engaged in the sport.
  • Automatic knives. In Connecticut, automatic knives are categorized as having a “spring release device.” This leaves it a big ambigous about whther assisted knives without a spring release are legal but most consider them to be fine only if the blade is under 1.5″ Automatic knives can be carried by firefighters and first responders that carry ID with them.
  • Schools are off-limits. Any sort of “dangerous weapon” cannot be carried at schools K-12 (either public or private) or at any school-sponsored activities.

As a finishing note for our summary, I will say that just because a knife is “legal” does not mean you won’t get in trouble for carrying it. While you might be fine in court, ornery police officers can make your life miserable. Do your best to stay as far within the laws as possible.

State Knife Law of Connecticut

According to the constitution of Connecticut, Article 1 (Section 15) every citizen has the right to bear arms for self-defense. If you have a CCW you can carry pretty much any gun you want.

Knives, however, are a different story.

The ownership of a knife or a blade is unrestricted in Connecticut as long as it is in your home. Selling and buying are also permitted but you need to know some basic legislation for carrying the knives in different places. Moreover, you cannot hide knives or blades while traveling.

A minor under 18 years cannot buy, sell or carry blades and knives without legal permission.
