Kyocera ceramic chef's knife

Ceramic knives are deceptively powerful: compared to steel, the zirconium oxide blade is 50% sharper and holds its edge roughly 10 times as long. They are also deceptively light, especially in the hands of one used to a steel blade. This makes the cutting process less tiring and often more enjoyable, since the blade cuts more cleanly than one's other knives. This reduced weight, however, requires a focus on accuracy instead of on speed, since speed is much more of a given yet the swift blade can nip a finger or ingredient not meant to be further cut.

Unfortunately, ceramic knives are not as all-purpose as metal tools, meaning one still sometimes needs a different knife if cutting through bones or tough vegetables (although I've successfully used mine to cut up a butternut squash). They also don't set off metal detectors, except that manufacturers often add a small piece of metal to the handle to ensure they do. And cutting against a ceramic plate or surface is not advised, as it can sometimes damage the knife. Nonetheless, for its weight and sharpness, my ceramic chef's knife is a tool I rarely cook without.
