Utility knives and box cutters are versatile, sharp tools that can come equipped with replaceable or retractable razor blades. They can be used in an office, warehouse or home, or when working on creative arts and crafts projects. They are mainly used for slicing through cardboard, opening shipping packages and packaging along with trimming materials like drywall, rope, paper, plastic wrap, vinyl, carpeting and more.

While utility knife and box cutter are terms often used interchangeably, there are differences between the two. Box cutters are lightweight, disposable or inexpensive tools that are mainly designed to open cardboard and cut through tape. They usually feature a fixed or snap-off blade. Utility knives are heavy-duty knives that are used for more precise and controlled cutting, such as construction tasks, working with craft supplies and DIY projects.

When you’re shopping for the best box cutter, start by looking for one that has a comfortable, ergonomic handle that’s easy to grip, a secure blade-locking mechanism for safety and blades that are easy to replace. Also, depending on the materials you’re cutting, make sure the box cutter you want has the right blade size. We carry box cutters with 9 mm blades, 18 mm blades and 25 mm blades.

To safely snap off a dull box cutter blade, extend the blade by one extra segment and use the built-in slit in the cap of your knife to bend and break the blade. Make sure the break line extends slightly past the handle and wear safety glasses while you do it. When you’ve broken off the dull blade, safely dispose of it by wrapping it in tape to prevent someone from cutting themselves and placing it immediately in the garbage.
