Utility knife uses include cutting and piercing a variety of materials, such as carpet, clamshell packaging, triple-walled corrugated and vinyl. The materials a utility knife can cut will depend on its exposed blade length and general durability.

Keep in mind, there are different utility knife blade types suited to different kinds of cuts. Any material that requires a piercing action to initiate the cut is best suited to a pointed-tip blade, such as the Slice 10528 blade. Rounded-tip blades, like Slice’s 10526 blade, offer added protection against accidental injuries.

Although Slice knives are much safer than typical steel blades, any knife is potentially dangerous. Make sure that you learn how to use a utility knife safely by following common sense precautions: cut at an angle away from the body, reduce distractions, and cut in one smooth motion where possible.

A Slice knife is a safety utility knife by design. Most companies consider only the handle when they try to make a safer knife. Their best option, the auto-retracting utility knife, still doesn’t address the part of the knife that actually cuts you: the blade.

Why are typical blades so dangerous? Steel is a relatively soft material, so to extend a steel blade’s working life, manufacturers sharpen it to an unsafe level. This workaround sacrifices user safety. Slice uses 100 percent zirconium oxide, an extremely hard material that holds its edge, so we don’t need to over-sharpen our blades in order to make them effective. Our proprietary grind cuts materials effectively but resists cutting skin. So a Slice knife has a smarter handle and a safer blade.

Slice’s Smart Retract feature adds another layer of safety to an auto-retracting utility knife. Where most auto-retracting knives pull the blade into the housing once the user lets go of the button, Smart Retract engages as soon as the blade loses contact with the cutting material. This safeguards against accidental slips while the blade is engaged. This new level of utility knife safety raises the bar, promising to redefine the question of, “what is a utility knife?

Most slider buttons require the user to push with the thumb while pulling the knife in the direction of the cut. These opposing forces cause a certain amount of strain that can be avoided with a design like Ergo Pull™, where the user pulls both the slider and the knife in the same direction.

This may seem like a small adjustment, but the results are impressive, especially when considering cutting tasks repeated over long shifts where there is a potential for cumulative strain injuries. In testing done by United States Ergonomics (an independent third-party testing agent), Ergo Pull™ technology resulted in less forearm effort, upper arm effort, and hand muscle strain than the standard push-blade lever utility knife.
