The Rare Earth ceramic knives are made from diamond hard zirconium oxide which is 40% stronger than steel. This high-purity zirconium oxide powder is compressed at very high pressures and heated in a furnace at temperatures of over 2700°F. This results in an extremely-hard blade, nearly as hard as diamonds and the abrasion performance is 60 times better than a metal knife. 

Additional features include:

• Health: lead-free, non-toxic, acid resistant, alkali resistant, never rusts.  
• Excellent performance: because of its extremely high density and brightness the knife does not easily breed bacteria, ensuring it is anti-bacterial, anti-fouling and easy to clean.
• Sharpness: the materials that make up a ceramic blade are very hard. It’s the second hardest material, ranked after diamonds. After it’s sharpened, it can keep its razor sharp edge and will not wear out.
• No metallic taste or smell: ceramic material is not very porous at all. This keeps the blade from transferring odours from one food item to another. 
• Sanitary: the density of ceramic blades is very high, and the blades have very little pores. A quick rinse in warm water can give your ceramic knife a good clean, rather than a thorough scrubbing on a metal knife.
• Lightweight: ceramic material is very light weight. Density of steel is 7.85g/cm3, ceramic knife's is 6.0-6.1g/cm3. The lighter the weight is, the less strain on your arms and shoulders.
• Rustless and no magnetism: There is no metal, so there is never rust and magnetism.
