As far as cutting tools go, ceramic knives rank right up there among the best and sharpest knives. It is highly popular not only because it is sharp as hell, but perhaps more well known to be able to maintain it far longer than knives made from other materials. Reading the reviews about ceramic knives, Kyocera ones in particular, has perked my interest in buying one to try and experience it myself. The only thing though is to convince my wife to buy a knife that costs several times as much as a normal knife is asking for.
