FAQ

Why a Ceramic Blade?

Because ceramic cutlery remains near razor sharp far longer than any steel blade does.  Under normal home kitchen use ceramic blade sharpness can last years without ever needing sharpening.

What are the main advantages of the ceramic knives?

The superior hardness, superior corrosion resistance, chemically inert, and a naturally non-stick surface are the main property highlights of ceramic knife blades.  In your kitchen these properties relate to a long lasting sharp edge, that will not rust or stain.  Ceramic blades are far more hygienic than metal - they will not react with your fresh food (will not turn food brown like metal knives) or alter the taste by depositing metal ions.  Ceramic blades rinse clean under running water (soap and water is recommended after cutting meat or fish).

What are ceramic knives made of?

These knives are made of Ceramic Zirconia, processed into Zirconium Oxide (white) or Zirconium Carbide (black), also called "modern ceramics".  Zirconia is second in hardness only to diamond and was originally developed for industrial applications where metal components failed.  Zirconia is extremely hard, wear resistant, and chemically inert.

How can I wash my ceramic knife, peeler, sheers, or scissors?

Ceramic knives are very easy to clean with a quick wipe since food does not stick to them. We do not recommend washing them in a dishwasher since the dishwasher may cause the knives to constantly bang against other utensils and eventually this could cause a chip to the cutting edge. Violent motion against other objects, especially hard plates, could chip the objects and/or the ceramic blade.  Ceramic blades rinse clean under running water (soap and water is recommended after cutting meat or fish).

How can I avoid damaging my ceramic knife?

You can chip the edge if you cut into bones or use on frozen foods. You can also break off the tip or snap off the handle if you use it to pry. Please handle the blade carefully. Only wooden surfaces or the new plastic cutting boards are recommended. Surfaces of marble, glass, china or steel will be cut (scored) by these blades and in time may impair the sharpness of the blade.  Bottom Line: Don't drop the blades on hard surface floors or use them as can openers and these ceramic blades will remain sharp for years of normal daily use.

How fragile are the ceramic knives? 

If the knives are dropped a small chip or knick along the cutting edge can result -- this much is true.  A dropped ceramic knife will usually not be damaged at all.   Modern ceramic materials are certainly not fragile.

The BIG difference is that metal knives quickly become dull with normal use while ceramic blades can remain sharp for years of normal daily use without sharpening

And, this would not be possible if the ceramic blade material was fragile...  Try one free for 30-days to see for yourself!

What should I choose--a white blade or a black blade?

Both white and black blade ceramic knives are made of Zirconia.  The white blades are composed of Zirconium Oxide.  The black blades are Zirconium Carbide.  They are made through the same manufacturing process except that the black blades are subjected to an extended final firing process that includes a precise "sintering" to produce the exotic Zirconium Carbide material.  The black, Zirconium Carbide blades can be up to twice as hard as the white blades -- but both are at least 7 to 10 times as hard as the common steel knife blade.

White is the natural color of Zirconia.  Manufacturers can also put white blade ceramic knives through a “carbon-infiltration” process to make the blade into black color to cater to consumers’ different preferences.  

All URI Eagle black blades are Zirconium Carbide -- a far more exotic and valuable material than the Zirconium Oxide.

Zirconium Carbide is naturally black in color.  One look at our Zirconium Carbide black blades and you'll be able to tell the difference between our Zirconium Carbide and the other brands' less valuable black colored Zirconium Oxide blades.  

Bottom line: Our exotic Zirconium Carbide blades are priced lower than many of our competitor's blades made from Zirconium Oxide -- so now you may choose the color you like without over-paying for the Zirconium Carbide -- (if you like the black blades and want the very best make sure they are Zirconium Carbide!).   They are both capable of the same long lasting sharpness and either is very durable -- both our white and black blades are covered by the same 5-year manufacturer's warranty and in-warranty sharpening service.
