Connecticut’s knife laws are among the most detailed and restrictive in New England. Whether you’re a collector, outdoors enthusiast, or simply carry a pocketknife for everyday tasks, it’s crucial to understand what’s legal-and what isn’t-when it comes to knives in the state.
What Knives Are Legal to Own?
- Legal to Own: Connecticut law allows ownership of virtually all knife types, including balisongs (butterfly knives), gravity knives, switchblades (automatic knives), dirks, stilettos, push knives, Bowies, and swords.
- No “Forbidden” Knives: There are no knives outright banned from ownership in Connecticut.
Knife Carry Laws: What and Where You Can Carry
General Carry Restrictions
- Automatic/Switchblade Knives: Illegal to carry in public if the blade is longer than 1.5 inches.
- All Other Knives: Illegal to carry in public if the blade’s edged portion is 4 inches or longer.
- No Distinction Between Open and Concealed Carry: The law applies equally whether the knife is visible or hidden.
Carrying in Vehicles
- Carrying any knife with a blade longer than 4 inches, or an automatic knife with a blade over 1.5 inches, in a vehicle is a Class D felony.
- Some exceptions exist (see below), but violations can result in up to five years in prison and/or a $5,000 fine.
Carrying in Specific Locations
- Schools: It is a Class D felony to possess any knife defined as a “deadly weapon” on public or private school grounds (K–12) or at school-sponsored activities.
- Parks and Local Restrictions: Connecticut does not have statewide preemption, meaning towns and cities can enact stricter knife laws. For example, some municipalities ban knives in parks or set lower blade length limits.
Key Exceptions
You may legally carry knives exceeding the standard limits if you fall under certain exceptions, including:
- Law enforcement officers on duty
- Military personnel on duty or in parade/assembly
- Transporting knives as merchandise or for display at authorized shows
- Moving household goods
- Taking a knife to/from repair
- Licensed hunters, fishers, or trappers while engaged in those activities
- Participants in authorized historic reenactments
These are “affirmative defenses”-if charged, you must prove you qualify for the exception.
Penalties for Violations
- Class D Felony: Carrying a prohibited knife in public, in a vehicle, or on school grounds can result in 1–5 years imprisonment and up to a $5,000 fine.
Local Laws and Preemption
- No Statewide Preemption: Local governments can-and do-impose additional restrictions. Always check local ordinances before carrying a knife, especially in cities like New Haven, Hartford, or Bridgeport, which may have stricter rules.
Notable Legal Rulings
- The Connecticut Supreme Court has recognized that certain knives (like dirks) are protected as “arms” under the Second Amendment, but practical restrictions on carry still apply.
Quick Reference Table: Connecticut Knife Laws

Best Practices
- Always measure your blade: The law is strict on length.
- Check local ordinances: Towns may have stricter rules.
- Don’t carry on school property or at school events.
- If you qualify for an exception, be prepared to prove it.
Connecticut allows the ownership of most knives, but carrying is tightly regulated-especially for blade length and automatic knives. Always check both state and local laws before carrying, and remember that violations carry serious penalties.
