Kyocera Ceramic Knife

I got a new knife. It's one of those Kyocera Ceramic knives. Apparently, the only thing harder than the type of ceramic that these knives are made of is diamond, so it's supposed to stay really sharp. And it is really sharp! It also doesn't stick to things like meat (maybe chese, but I haven't tried) like steel knives do, so it just slips through. It was really cheap too compared to the US; about $18USD, but in the US, they are around $40 -$60 for the small one I have, and more than a hundred for the bigger ones. One site said that this is due to a huge import duty that the US has on them. I really needed a new knife, my old one was a $5 one that I used as a can opener once.
