How to Sharpen Ceramic Knives
Unlike metal knives, ceramic ones do not absorb any oils or acids. They don’t leave even the slightest metallic taste. They are also said to be twice as sharp as steel knives. Ceramic blades are harder that steel ones, so they don’t need to be sharpened as frequently. In fact, you can sharpen a ceramic edge ten times less than you would sharpen a steel one. The only thing harder than ceramic are diamonds. That is why ceramic knives are sharpened with diamond sharpeners. A well-made ceramic knife is also lightweight. A steel blade weights twice as much as a ceramic one. However, as any porcelain such blades can be easily damaged. You should only use them for cutting boneless meat, fruits and veggies. Be extra careful when cutting raw foods like apples or potato. If the product is difficult to cut, never try to twist your blade from side to side. You may simply break it. Another important issue is storing. A ceramic knife cannot be stored with metal tools or cutlery. You should keep it separately, preferably in a box. And try not drop in onto hard surfaces because, like a porcelain cup, it will break into pieces.
