About Ceramic Knife:
Ceramic knives are a relatively new invention and always expensive. Basically, they're made out of a high-purity zirconium oxide powder that is compressed at very high pressures and heated in a furnace at temperatures over 2700°F. This results in an extremely-hard blade, nearly as hard as diamonds.
Features:
1.Special Materials: Using high-tech Zirconia crafted, high-density, high hardness, never wear, hardness (HRA87) is next to diamond, and abrasion performance is 60 times better than metal knife; 2.Healthier: Lead-free, non-toxic, acid resistance, alkali resistance, never rust, health environmental protection; keep food color, flavor, enjoy the flavor, do not have any reaction to food, real health products! 3.Excellent performance: because of its extremely high density and bright the knife is not easy to breed bacteria, cutting fish, fruits, vegetables and other clear-cut, anti-bacterial anti-fouling, easy to clean. 4.Elegant Appearance: Appearance as jade-like soft moist, fine texture, adding to the enjoyment of the noble.

Test result:
Cut one apple with a sharpened stainless steel knife and another with a ceramic knife. After 15 minutes, the apple cut with ceramic knife hardly oxidized at all (see right picture below), while the one cut with metal knife already showed some signs of discoloration. Fruits will not oxidize and turn brown so fast when using ceramic knife to cut it
