Kyocera knives feature advanced ceramic blades. Ceramic's strength and density allows it to be ground to a microscopically precise, rock-hard edge; Stays razor-sharp 10 times longer than conventional high-carbon steel blades. Ceramic blades never rust and are impervious to acids, oils, and salt, so they never absorb flavors or alter food's taste, smell, or appearance. Typically half the weight of their steel counterparts, ceramic knives are exceptionally comfortable to use, even for lengthy, repetitive cutting tasks. Made in Japan.
