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.
