Zirconia Knife

Zirconia knife is a type of cutting tool made from zirconium dioxide (ZrO2) ceramic material. Zirconia knives are known for their hardness, sharpness, and resistance to wear and corrosion. They are typically used in food preparation and other applications where a precise and sharp cutting edge is required. Zirconia knives are also known for their lightweight and non-reactive properties, which make them an attractive alternative to traditional steel knives.
