Kyocera Gen series kitchen knife with black handle and 12.5 cm micro-serrated blade

Chef's knife with a 12.5 cm high-tech ceramic blade (zirconium oxide) and a micro-serrated edge.
The blade material is the second hardest known material, surpassed only by diamond. To achieve this razor-sharp edge, Kyocera has undoubtedly entrusted the knives to the skilled hands of traditional artisans, who hand-sharpen them.
Because it is made of ceramic and contains no steel, this knife does not oxidize food, does not impart odors or flavors, and its edge stays sharp up to 10 times longer than that of conventional steel knives.
