The main difference between Slice knives and other safety knife manufacturers is that the Slice cutting tools have a ceramic blade that is durable and designed with patented finger-friendly technology. The company claims that their ceramic blades reduce the consequences of accidents with a safety knife, and especially protection against accidental cuts.

Slice claims that its ceramic zirconium oxide safety blades last 11 times longer than other blades. In addition ceramic safety blades are chemically inert and will not rust. They are also non-conductive and antimagnetic. 

But despite the positive properties of ceramic blades, they are not suitable for everyone. Ceramic blades can chip off and therefore should absolutely not be used in food and pharmaceutical production facilities. They are not magnetic and will not show up on x-rays.

The blade instantly self-retracts when it loses contact with its cutting material
