Also known as zirconia.
What are ceramic knives made of.
In december 2014 we have done a new comprehensive test with ceramic knives of multiple manufacturers.
A ceramic knife is a knife designed with a ceramic blade typically made from zirconium dioxide zro 2.
First of all they aren t magnetized so you can t store them on a magnetic strip.
In this test we have compared the ceramic knives with comparable kitchen knives made out of steel.
It has its popularity for its hardness.
Clearly it is basically a knife made of tough and durable ceramic.
These knife blades are usually produced through the dry pressing and firing of powdered zirconia using solid state sintering.
Yes they re really made of ceramic.
We have tested the knives on sharpness how long they remain sharp user friendliness how it holds under pressure and how it reacts to sharpening.
The reason is that kyocera blades are made from zirconium oxide which is a state of the art ceramic material that is wear resistant and extremely durable.
Ceramic knives are a fantastic cutting option for those who do a lot of chopping and dicing in the kitchen and don t want to fuss with the sharpening requirements of metal blades.
It s very hard significantly harder than stainless steel or carbon steel.
Storing your knives is a whole other conversation but there are some things worth knowing about ceramic knives.
The most common ceramic for knives is zirconium oxide also known as zirconia.
The mohs scale of mineral hardness of ceramic is 8 5 while steel is just 4 5 while diamond as the top of the list is 10.
But this isn t the same ceramic that s used to make your coffee mug.
Second since they re both super sharp and super brittle a protective cover is a good idea for your fingers and for the knife.
The material is also called zirconium dioxide and zirconia.
