Kyocera advanced ceramic blades offer superior edge retention, holding their edge at least 10 times longer than other professional blades, including high carbon steel.
Brand new ceramic, high carbon and stainless steel knives were put into a Honda “sharpness testing” machine. The tester holds each blade with a constant force against a stack of paper and then slides the blade 3.5 inches to produce a slicing action. Paper was used because it’s much more abrasive than vegetables. As the test is repeated 1,000 times, the ceramic blade stays sharper longer than the other two blades.
Not all ceramic knives are created equal. These unretouched photos show a Kyocera advanced ceramic blade and another ceramic brand magnified 562 times. Kyocera’s micro-grain ceramic is more dense, and its cutting edge is sharper – just two reasons that Kyocera is the undisputed worldwide leader in ceramic cutlery.
