I tried one. My wife broke it, and not soon enough.

I've had a Kyocera for a long time. It was a gift something of a novelty or me . It gets used a couple times a year. Sharpening it will be a challenge , best accomplished with diamond plates, and like all knives, they will dull... and chip, and maybe crack.

I have a Chinese (Shenzhen) paring knife. It's pretty sharp, and should stay that way for a while. It didn't cost much, so if it gets dropped and breaks, or chips, it wouldn't upset me that much. It's a little thicker than I would like, but probably needs that for strength.
