In terms of safety, steel blades start out far too sharp. It's important to reiterate that Slice blades do not start out as sharp as steel blades or ceramics from other manufacturers. And, because of their safer edge, Slice's recyclable blades do not require special sharps disposal boxes.Īs with any cutting tool, you need to bring out a blade replacement as soon as your edge is too dull. Slice's longer lasting blades also reduce potentially dangerous blade handling, as they don't need to be switched nearly as often as steel. It’s important to note, though, that the safety edge is unique to Slice and doesn’t apply to other ceramic blades. Steel blade manufacturers sharpen their edges aggressively-way beyond what's needed to cut materials-in order to compensate for the softer metal's rapid dulling. Zirconium oxide's natural edge retention allows for Slice's proprietary finger-friendly ® grind, which is designed to be safer to touch while maintaining its cutting performance. Slice takes advantage of this property to create craft blades, utility blades, box cutter blades, and more that stay sharp 11 times longer than steel. It measures 8.2 on the Mohs hardness scale, compared with 4.5 for steel. Our blades are safe up to 1600 degrees Celsius and therefore ideal for sterilization and laboratory settings.Īnother defining property of zirconium oxide is its hardness. Zirconium oxide is non-sparking, non-conductive, non-magnetic, chemically inert, and never rusts. Slice replacement blades are made with 100 percent zirconium oxide, an advanced ceramic material that combines a number of useful features to set it apart from typical steel blades.
