However, when sharpening is needed, they cannot be resharpened the same way as steel blades, which are often sharpened with a ceramic whetstone. To sharpen the edge of a blade a material harder than the one that is being sharpened is required, and ceramic knives are usually sharpened with industrial grade diamond sharpeners.2.Health (Not rust): Our ceramic knife is made of biomedicine material,not including nickel,lead and other heavy metal elements. it will not bring allergic reaction. After 1600 degres high temperature sintering,the blade is entire compact,non-hole,not-magnetism,non-conductive,non-slabby,and easy to clean. Ceramic material has strong chemical stability,anti-corrosion,no chemical reaction with food,keep food fresh and tasty. Their chemical inertness to both acids and alkalis,and their ability to retain a cutting edge upto ten times longer than forged metal knives, makes them a very best culinary tool for slicing and cutting through boneless meat,vegetables and fruits etc..Disadvantage: Since they are very tough they cannot be used for chopping iron or cutting bones or prying open things which may cause the cutting edge to chip off or the blade to break free. The tips of these knives are resistant to rolling and pitting but may break when dropped to ground.Production: These knifes are generally produced by compacting Zirconia powder using high pressure presses which apply a pressure of around 300 tons to produce blade shaped blank.These blanks are very brittle and fragile which can be shattered by a slight blow and special binders are used to retain the shape of the blank till the firing process. Like all ceramics these are hardened by firing at around 1600 degree celsius for about 2 days in kilns. the result is a very tough and blunt blade which needs to be sharpened by hand to get the desired cutting edge.The blades are sharpened by grinding the edges with a diamond dust coated grinding wheel.For more information,pleasecontact us!www.fairwayfinechina.com
