More About Slice Box Cutter Replacement Blades

What Are Box Cutter Blades?

Box cutter blades are removable components that include the cutting edge of your box cutter. Different styles of box cutter blade exist for different tools. These include snap-off metal blades and metal or ceramic one-piece box cutter replacement blades. Replacing the blade in a box cutter is a common cause of injury with standard metal blades because their edges are extremely sharp.

What Are the Important Box Cutter Safety Considerations?

When looking at safety, it's important to consider several different aspects of your tool. Dimensions are relevant not just when changing blades, but also when looking at how much blade will be exposed during cutting. How to change a box cutter blade will differ with various handle styles and is also worth considering, since accidents often happen when users switch blades in their knives. The easier the box cutter blade replacement process, the less likely you are to be injured.

Blade disposal is also important. If you're using dangerous metal blades, a sharps box is essential. With Slice's finger-friendly safety blades, you do not require a sharps disposal setup. Lastly, if safety is your most important concern, it makes sense to choose a rounded tip rather than a pointed tip. However, for some applications that require piercing to initiate the cut, a pointed tip is required. Be sure to take this into account when choosing your blade.

Why Choose Ceramic Blades?

Slice blades are designed with safety in mind. We use 100 percent zirconium oxide, which is much harder than steel. Because of its hardness and edge retention, our ceramic material doesn't need to be sharpened to excess in order to be effective. It can start out less sharp than a dangerously sharp steel blade and will retain cutting effectiveness for an average of 11 times longer. In addition, our ceramic blades are non-conductive, non-sparking, chemically inert, and never rust, making them ideal for many industrial applications.

How Often Should I Replace My Box Cutter Blade?

All box cutter blades need to be replaced as soon as they get too dull and require excessive pressure to effectively cut material. With a steel blade, this happens very quickly as steel is a relatively soft material. Slice ceramics are much harder and therefore hold their edge longer. So while your Slice blade will eventually dull, it will take eleven times longer to do so.
