Ceramic knives
Ceramic knives have become popular in recent years due to their outstanding ability to maintain sharpness and a good resistance to corrosion and acids. Ceramic knives are made of zirconium oxide which is compressed at very high pressure and hardened in an oven at about 1500 degrees Celsius. The result is an extremely hard blade that is comparable to the hardness of a diamond. The sharpness of the ceramic knives is very good and the knives keep sharp for a very long time.
