Zirconia Ceramic blade

Zirconia Ceramic blade

Ceramic blade for kitchen knives.

Ceramic blade will not corrode in harsh environments, are non-magnetic, and do not conduct electricity at room temperature. Because of their resistance to strong acid and caustic substances, and their ability to retain a cutting edge longer than forged metal knives, ceramic blades are a much more suitable culinary tool for slicing boneless meat, vegetables, fruit and bread.
