The blades of Sunward ceramic knives are made of nano-sized zirconia powder, whose density is higher, resulting in extremely hard, wear resistant, and chemically inert, superior to steel blades.

Rust & Stain Proof- Ceramic knives are impervious to the food acids or salt water, unlike steel knives discolored. They are attractive and work fine in a home kitchen across advanced countries, especially in Japan.
No allergy concerns- Zirconia is a ceramic biomaterial, applied in tooth enamel, joint prosthesis etc. As such, ceramic knives can be used by people with certain allergies (chemically inert). In addition, ceramic knives maintain the fresh taste of food. Won?t turn fruits and vegetables brown or leave any metallic taste or smell.
Easy to Clean- Sunward?s ceramic knives are made by bonding the nano-sized particles (200~400 nm) in a sintering treatment over 1400?. Compared to other ceramic knives, Sunward?s are made of nano-sized powder, whose surface is non-stick. With a special surface treatment, it helps prevent bacterial contamination. The knives are easy to clean by hand washing or towel wipe.
Easy to use- Ultrashape long life blade keeps its cutting edge more wear-resistant than steel and is ideal for general household use. Furthermore, the tang of Sunward?s ceramic knife is well extended into the handle to make a strong connection; a countering-weight is added in the handle, for a lightweight, perfect balance, to make it a pleasure to use.
