Kyocera knives have unique blades made of zirconium oxide, which will hold their edge much longer than steel, will never rust and will not alter the color or taste of food. Your Kyocera advanced ceramic knife will bring you many years of trouble-free use when you follow these instructions.
Ideal for straight cuts of fruits, vegetables and boneless meats.
Always use with a plastic or wood cutting board. Avoid cutting on marble, stone, glass, plates and tile.
Use your conventional steel knives for carving, prying, boning, and cutting frozen foods and cheeses. These applications involve twisting and flexing, which require a more flexible material than ceramic.
Hand-wash with water and liquid dish soap; do not wash in the dishwasher.
For discolorations not removed by normal washing, wash only the blade with a mild bleach solution.
Dropping on hard surfaces.
Hitting against china or flatware.
Putting the blade in open flame (ceramic conducts heat).
Scraping hard surfaces.
Turning the blade on its side to smash garlic or other items.
Applying force to the side of the blade.
Store in a knife block, sheath, tray or in a dish drain.
Use care when storing and removing the knife from a knife block to avoid tip damage.
Storing any knife upright (sharp edge up) or sideways in a knife block reduces wear to the knife edge.
All knives dull over time. A soft metal blade (stainless steel) “rolls” as it becomes dull. Harder metals (such as high carbon steels, titanium, or carbide) hold their edge longer, but dull differently. As the material hardens, it becomes less forgiving and tends to slightly chip instead of roll. Advanced ceramic blades are simply the next and final step on this hardness scale, harder than any metal.
Ceramic starts out sharper and stays sharper longer. In time, you may notice micro abrasions or nicks on the blade’s edge. This is the normal process by which any hard material blade will dull. The existence of microchips does not necessarily mean the knife is dull. You will find that it performs well for quite some time. When the knife becomes too dull to use, Kyocera’s re-sharpening process will “flatten out” the edge of the blade (removing all chips) and then reestablish a new sharp edge. Larger chips and broken tips can often be corrected by re-sharpening as well.
