Have you come across utility knives on your kitchen items? Now wondering “What is a utility knife used for?” To find out, you first need to know  “What is a utility knife?” So let’s get started.

Simply put, a utility knife is a 4“ to 7”  long versatile knife used for various food prep tasks around the kitchen. It is mainly designed for a wide variety of slicing fruits and vegetables, tender pieces of meat, fish, or sandwiches.

Legal Considerations for Utility Knives:

Regarding utility knives, being aware of all legal considerations before buying them is a must. In this case, I always suggest that everyone check the federal, state, and local laws, blade length and type restrictions, and concealed and open carry laws.

Federal, state, and local laws:

First of all, federal law doesn’t prohibit carrying any knives, it just addresses where you can carry them under the Switchblade Knife Act of 1958. However, the federal government banned certain types of knives such as switchblades or ballistic knives from interstate shipment, sale, importation, or possession. That means it restricts the sale and transportation of knives, while state and local laws address specific restrictions on blade length, certain types of knives, or possession in certain locations you can carry.

Restrictions on blade length and type:

Restrictions on blade length and type for utility knives can vary depending on the jurisdiction. Many jurisdictions impose restrictions on the maximum length of blades that can be carried in public. The maximum allowable blade length can vary significantly, ranging from 2 to 4 inches or more. But they don’t allow to carry Switchblades, Balisong (Butterfly) Knives, thrusting knives, Double-Edged Blades, and Automatic Knives.

Concealed and open carry laws:

Concealed carry and open carry laws prohibit the carrying, of either concealed or open certain types of knives. But they don’t address utility knives. However, it can vary depending on the jurisdiction. So research and understand concealed carry and open carry of utility knives in your jurisdiction.


Whether it is cutting, trimming, scraping or opening, utility knives perform well in all tasks. So, you can do all the tasks easily and more efficiently. However, just like other knives utility knives also require proper maintenance to ensure both effective performance and personal safety.
