Why Ceramic Blades? Hardness & Sharpness.

On the Mohs hardness scale, Metal blades are rated 5.5 vs. Ceramic blades at 8.2, second only to diamonds. Harder edges maintain sharpness longer, cut better, and require replacement far less frequently. In fact, depending on use, you can go weeks or months without having to replace a single ceramic blade. They also last up to 10x longer!

A single Slice ceramic blade is equivalent up to 10 high-end double-sided metal blades or up to 20 high-end single sided metal blades. In terms of safety, less blade changes also mean less risk of injury.

What makes your product special?

Our proprietary blade manufacturing process combines a unique sharpening angle and thicker ceramic material, resulting in a very unique patented blade that’s safer to the touch vs. metal, and requires pressure to initiate the cut — via our handles. Hence, general blade handling and blade-replacement with Slice ceramic blades is infinitely safer vs. those same activities with traditional metal blades, yet still allows for a wide range of cutting applications.

What has been the best part of your experience?

You can’t simply duplicate a metal blade in ceramic material and achieve what we have created with our current products. There’s a tremendous amount of engineering required on not only the blades and handles individually, but there’s also an incredible amount of engineering required on the combination of the handles and the blades working together in order to produce the desired balance of safer-usage and cutting capability. Even today, for our next generation of products that are currently under development, we spend the majority of our time finding the right balance between handle and blade through trial and error and what seems like endless prototypes. The best part definitely has to be seeing peoples first-time reactions when cutting cardboard with Slice and they realize how awesome the Slice ceramic blade is.
