Now there are some cheap ceramic knives in Aliexpress， it is made of aluminium oxide， but the seller still claim it is zirconium oxide. The price of zirconium oxide is 25 times expensive than aluminium oxide. Aluminium oxide is not hard as zirconium oxide， worst of all， aluminium oxide is harmful to health.

We promise all of our ceramic knives are made of zirconium  oxide， if not true， refund all money.








Ceramic Knives are modern innovation designed to improve your culinary experinces. The hardness， strength and corrosion resistance of Zirconia (ZrO2) Ceramic， provides significant advantages compared to traditional stainless steel knives: the ceramic blade will hold its edge much longer than regular steel， go literally years without re-sharpening when you use these stain and rust proof knives， impervious to food acides that eventually discolor steel products， ceramic knives do not leave hehind any metallic taste of smell， helping to maintain each food?s taste. It is perfect for cutting vegetables， fruits， meat， fish etc.

Your Ceramic Knife is an environmental， friendly， chemically stable product， which is rust-free and non-corrosive.

The non-stick surface is easier to clean than steel and will not tarnish or absorb food odors， they are easy to care for by rinsing in warm water， and they do not need to be fully dried when stored.  


About Ceramic knife

Ceramic knives are a relatively new invention and always expensive. Basically， they're made out of a high-purity zirconium oxide powder that is compressed at very high pressures and heated in a furnace at temperatures over 2700°F. This results in an extremely-hard blade， nearly as hard as diamonds.


SHARPNESS - The materials that make up a ceramic blade is very hard. It?s the second hardest material， ranked after diamonds. After it?s sharpened， it can keep its razor sharp edge and will not wear out.

NO METALLIC TASTE OR SMELL - Ceramic material is not very porous at all. This keeps the blade from transferring odors from one food item to another. You can cut something spicy， give it a quick rinse and then cut something else. The spiciness won?t transfer to the next food item.

SANITARY

The density of Ceramic blades is very high， and the blades have very little pores. Just like your face， the fewer pores there are， the less dirt and grime can get into the pores. A quick rinse in warm water can give your ceramic knife much clean than a thorough scrubbing on a metal knife.

LIGHTWEIGHT - Ceramic material is very light weight. The lighter the weight is， the less strain on your arms and shoulders. You can rip through all you?re cutting like a pro.

RUSTLESS -There is no metal， so there is never rust.


Test:
Cut one apple with a sharpened stainless steel knife and another with a ceramic knife. After 15 minutes， the apple cut with ceramic knife hardly oxidized at all (see right picture below)， while the one cut with metal knife already showed some signs of discoloration. Fruits will not oxidize and turn brown so fast when using ceramic knife to cut it.
