    • Hi Catherine, Thank you for taking the time to leave a kind comment! :) 

      Hopefully you won't need a replacement blade for a while--our double sided Slice ceramic blades lasts an average of 11 x longer than steel blades. You can learn more about this at the following article:  How Long do Slice Ceramic Blades Last? 
      Thank you!-- //SLICE Team//

More About Our Auto-Retractable Safety Box Cutter

What Is a Box Cutter Used For?

As the name suggests, box cutters are often used to open corrugated material but they can also handle a wide variety of other materials such as clamshell packaging, tape, card stock, and plastic film. Be sure you choose the right blade tip (rounded or pointed) for your application.

Why Buy a Box Cutter From Slice?

Slice's award-winning J-hook design changed ideas about how to use a box cutter. Not only does the wrap-around handle protect the user from staples and other debris, but the angle of the blade housing reduces unnecessary blade exposure. The handle also acts as a built-in guide, giving the user more control over the angle of the cut. Simply put, the Slice box cutter is a safety box cutter, from its finger-friendly ceramic safety blade to its innovative tool design.

What About Replacement Blades?

When searching how to put a blade in a box cutter, you'll find all kind of complex procedures involving screwdrivers and safety gloves. Not so with Slice's safe box cutters. Our tool-free blade replacement and patented finger-friendly edge make blade changes easy and safe. And because our blades last 11 times longer than steel, you'll be replacing blades less often.

For most applications, the Slice 10404 rounded-tip blade adds extra safety protection, but for jobs that require a piercing action to initiate the cut, try the 10408 pointed-tip blade.

Which Slice Box Cutter Is Right For Me?

Slice manufactures two styles of J-hook tool: the retractable box cutter and the manual, or fixed-position blade, box cutter. The manual box cutter is ideal for users that are cutting constantly with few breaks in between strokes. The retractable box cutter has an added layer of safety because the retracting blade prevents the user from accidentally leaving the blade exposed when the knife is not in use.

Both Slice box cutters can handle material depths up to and including double-walled corrugated. If you're cutting something thicker, like triple-walled corrugated, we recommend one of our utility knives.
