🌳 Connecticut Knife Laws
Overview
Connecticut does not have statewide preemption, so local ordinances may impose additional restrictions. Both open and concealed carry face restrictions. Blade length limits apply at 4 inches in certain contexts. Switchblades and balisongs / butterfly knives have restrictions.
Quick Legal Facts
Carry Laws & Blade Length
Connecticut does not distinguish between open and concealed carry. Carrying any knife with an edged blade of 4 inches or more, any switchblade with a blade over 1.5 inches, or any dirk knife or stiletto is prohibited regardless of carry method (Class E felony). Exceptions exist for military, licensed hunters/fishers, and merchandise transport.
Statute: 53-206.
Same restrictions as open carry. The prohibition under § 53-206 applies to carrying 'upon one's person' with no distinction as to concealment. Knives with edged blades under 4 inches (excluding switchblades, dirks, and stilettos) may be carried.
Statute: 53-206.
Two thresholds apply. Any knife with an edged blade of 4 inches or more is prohibited to carry (with exceptions). Automatic/switchblade knives have a stricter 1.5-inch blade limit. Both thresholds measure the edged portion of the blade. Same limits apply for weapons in vehicles under § 29-38.
Knife Type Legality
| Knife Type | Status | Details |
|---|---|---|
| Switchblades | Restricted | Switchblades with blades over 1.5 inches are illegal to carry on one's person or possess in a vehicle. Switchblades with blades at or under 1.5 inches are legal to carry. The exemptions for long knives (military, hunters, etc.) do not apply to switchblades. Ownership at home is unrestricted. |
| Balisongs / Butterfly Knives | Restricted | Balisongs are not classified as switchblades because they lack an automatic spring release device. They are treated as ordinary knives subject to the general 4-inch edged blade length limit. Legal to carry if the edged portion of the blade is under 4 inches. |
| Disguised Knives | Unclear | Not specifically addressed in Connecticut statutes. Disguised knives are legal to own. Those with blades of 4 inches or more are prohibited to carry under the general blade length limit. Shorter disguised knives may be legal, but the catch-all provision for 'any other dangerous or deadly weapon or instrument' creates some uncertainty. Statute: 53-206. |
| Assisted-Opening | Unclear | Connecticut prohibits knives with an 'automatic spring release device' with blades over 1.5 inches, and it is unclear whether assisted-opening mechanisms qualify. No appellate court has ruled on the distinction. Connecticut has not adopted a bias-toward-closure exception. AKTI recommends avoiding assisted-opening knives in Connecticut. Statute: 53-206. |
| Ballistic Knives | Unclear | Not specifically addressed in Connecticut statutes. Not enumerated in the prohibited weapons list under § 53-206, but the catch-all provision for 'any other dangerous or deadly weapon or instrument' may apply. Federal law (15 U.S.C. § 1245) separately restricts them. Statute: 53-206. |
