Cutting Safety and Ceramics: Blade Design Matters

By TJ Scimone

Every safety manager is looking for safer tools to protect their workers. Perhaps you’ve heard that ceramic-bladed cutting tools are safer. Don’t fall into the trap of believing that, because not all ceramic blades are created equal.

In fact, most of the ceramic-bladed cutting tools on the market are manufactured in the exact same way as metal-bladed cutting tools, making them just as dangerous. When you add in their tendency to break under force, using traditional ceramic blades in your cutting tools can be a costly accident waiting to happen.

Take a look at this video to see the differences between metal blades, typical ceramic blades, and Slice’s® safer ceramic blades:

The Slice Safety Blade Difference

Only Slice manufactures a true safety blade, using a proprietary double-angle grind that produces a finger-friendly® blade edge. This edge is safe to touch, making you less likely to suffer a laceration injury from incidental contact either during tool use or blade replacement. This grind is so unique that Slice has a patent pending on it.

What makes our blades so different and how do they add an additional safety measure to our cutting tools? We developed our safety blades by considering the nature of human skin. It’s flexible, yet tough on the outside, while being soft on the inside. In order to avoid piercing the skin, we used a thicker zirconium oxide ceramic blade and applied a grind that shortens the initial cutting zone of the blade. It’s this zone that does the actual cutting.

In metal blades, and traditional ceramic blades, the steep angle of the grind creates a long, sharp initial cutting zone. Stainless steel is comparatively soft, so it dulls quickly. Steel blades are made excessively sharp in an attempt to extend the working life of the blade. Ceramic blade manufacturers typically copy this process, even though it isn’t necessary for advanced ceramics, which are stronger than stainless steel.

Our wider angle displaces the downward force of the blade against your skin. Our blades bend the skin away from the edge:

As a result, it takes more force to pierce your skin with a Slice blade than it does with a traditional metal or ceramic blade. If piercing does occur, our blade is unlikely to cut as deeply as a traditional blade. When external force is applied to extremely narrow traditional blades and their long cutting zones, the force has nowhere to go but into your skin.

Does this mean that Slice tools can’t cut you? Of course not! They’re cutting tools, after all. If they couldn’t cut, they wouldn’t be installed in over half the Fortune 1000’s facilities. Although our finger-friendly blades are safer to touch, you should always exercise caution when using any blade.

Safer Tools for Every Cutting Task

From our micro-ceramic blade knives to our scissors, Slice applies our safer, yet effective, grind to the blades on all our tools. We also design with ergonomics in mind, making tools that are more comfortable to use and less likely to cause repetitive strain injuries. We feature auto-retractable versions of most of our cutting tools, limiting blade exposure and reducing the likelihood of accidental lacerations.

All our tools that use replaceable blades ship with rounded-tip blades, because the rounded tips are less likely to cause puncture injuries. Pointed-tip blades are also available, as these are preferable for some applications where you initiate the cut with a puncture. We make a complete line of replacement blades. Many of our blades are compatible with multiple handle designs, making our tools more versatile, as well as safer and more economic than other tools on the market.

Eye-Catching and Functional Designs

Slice also recognizes that the appearance and functionality of a tool can affect how quickly workers adopt it as part of their preferred tool kit. Take the award-winning design of our 10503 Auto-Retractable Box Cutter:

This innovative box cutter design positions the tool as a natural extension of your wrist and forearm, making it more comfortable for extended use. At the same time, the blade’s cutting depth is perfectly designed to work with corrugated materials, allowing a worker to open a box without damaging the contents.

For more innovative designs, check out our 10580 Precision Knife that moves with your finger, giving you superb cutting control, our mouse-shaped 10200 Safety Cutter that is handy for thin materials, and our 10514 Auto-Retractable Mini Cutter with its convenient built-in magnet. For routine cutting needs, Slice makes a comprehensive line of utility knives, box cutters, and precision knives, as well.
