The Ceramic Utility Knife is a completely non-metallic zirconia ceramic razor blade that can be used in any “Stanley” style blade holder. The carbonized ceramic blade goes through a 2-stage sintering process that increases hardness, strength, and sharpness, over standard white ceramic blades. With its corrosion resistance, edge retention, non-magnetic, and non-conductive properties, the Ceramic Utility Knife can be used in situations where a traditional steel blade would not be desirable.
