Crafted in Japan, Zirconia Z206 is Kyocera’s proprietary advanced ceramic. This one-of-a-kind advanced ceramic material has very dense particles and extremely tight molecules, which leave minimal voids. This translates into a stronger, denser blade that holds an edge longer than other ceramic knives. The thinner blade on a Kyocera Advanced Ceramic knife, slicer, or peeler means minimal resistance. Clean, precise, less-intrusive cuts, using less pressure, are what make the Kyocera ceramic utensil so unique.
