Kyocera Ceramics knives are made of the technical material zirconia. They have revolutionary characteristics in comparison to conventional steel knives. The ceramic knives are harder than any other cutting tools, except diamond and yet are lighter than steel.
They also stay sharp for considerably longer than other knives, normal household use would mean sharpening approx. every 10 years, for professional daily chef use sharpening would be needed around every 3 years.
The Ceramic blade has a smoother surface than steel, enabling it to slice through any type of food effortlessly. This smooth surface also makes Kyocera ceramic knives more hygenic. They are also corrosion free and neutral to taste making them an ideal solution in food preparation.
