Knowing the pocket knife rules and laws for each U.S. state is essential for anyone who carries or collects knives. At KBS Knives Store, we emphasize responsible ownership and informed carrying practices. Understanding the nuances of state and federal regulations will help you avoid unnecessary legal issues and ensure you can confidently carry your knife within the law.
We provide the latest available information, but knife laws can change quickly—always confirm with your state’s current statutes. In addition, remember that many public spaces, such as schools, airports, theaters, amusement parks, and certain government buildings, prohibit pocket knives regardless of size or type.
How Pocket Knives Are Defined & Classified
Not all knives are created equal. Pocket knives vary in design, purpose, and legality. Common types include:
-
Folding Knives: Compact, portable, with a pivot mechanism that folds the blade into the handle. Often equipped with locking mechanisms.
-
Fixed Blade Knives: Sturdy, non-folding knives, ideal for hunting, camping, and survival tasks.
-
Multi-Tool Knives: Pocket knives with additional tools like pliers, screwdrivers, and can openers—perfect for all-around utility.
Blade Shapes & Their Uses
-
Drop Point: Strong and versatile for a wide range of cutting tasks.
-
Clip Point: Designed for precision and piercing.
-
Tanto: Inspired by Japanese blades, ideal for tactical and self-defense applications.
Legal Definition of Pocket Knives
The legal definition of a pocket knife differs by jurisdiction but often considers:
-
Blade Length: Many states limit carry based on size.
-
Opening Mechanism: Assisted or automatic openings may be regulated.
-
Intended Use: Knives marketed for self-defense can face stricter scrutiny.
Federal Knife Laws
-
Federal Switchblade Act of 1958: Prohibits interstate commerce and importation of switchblades but does not ban possession in states where they are legal.
-
TSA Regulations: Carry-on knives must be under 2.36 inches, without fixed or locking blades. Larger knives must go in checked luggage.
-
Federal Property Restrictions: Many federal buildings prohibit pocket knives entirely.
State-by-State Pocket Knife Laws
Every state has unique rules on possession, blade length, and carry method. Some, like Kansas and Texas, are very permissive, while others, like New York and Washington, impose strict limitations. For example:
-
California: Allows open carry of most knives; switchblades over 2 inches are banned.
-
Utah: Permits nearly all knives for lawful adults.
-
Washington State: Bans switchblades and certain concealed carry knives.
