A ceramic knife is a knife made out of very hard and tough ceramic, often zirconium dioxide (ZrO2; also known as zirconia). These knives are usually produced by dry pressing Zirconia powder and firing them through solid-state sintering. The resultant blade is sharpened by grinding the edges with a diamond-dust-coated grinding wheel. Zirconia is 8.5 on the Mohs scale of mineral hardness, compared to 4.5 for normal steel and 7.5 to 8 for hardened steel and 10 for diamond.
The very hard edge rarely needs sharpening.
Ceramic knives ideal for slicing fruits, vegetables and boneless meats.
Ultra sharp ceramic blades stay sharp 10x longer than steel.
Won't brown foods or transfer metallic taste or smell.
Rust-proof, stain-proof and germ resistant.
Comfortably ergonomic and perfectly balanced.
