I'm very impressed with the ceramic blade of this Kyocera knife. You can see here on Amazon that Kyocera is making a submarket with this ceramic technology. It really delivers -- it's sharp, light, and seems strong in the up/down direction. I've used a lot of different knives across the price spectrum for a broad range of cooking tasks, and this one slices cleaner, faster, easier than any knife I've ever used.
I never *really* imagined using a knife this sharp. It's what I imagine a hand-crafted Spanish Toledo steel sword or Samurai blade would be like. Except smaller. And lighter. And white.
However, be careful! Because it is both very lightweight and very sharp, the knife handles differently than any knife I've used before. And it is sharp enough to do real damage quite quickly. For instance, I received one of these knives as a gift from a friend who had recently got one for herself. It turns out that we *both* cut our fingers in the first few weeks of using our fancy new knives! In each case, we sliced through a fingernail that with a less-sharp knife might have afforded some protection. (I'm typing now with a bandage on my index finger.) I will be very attentive while using this knife from now on!
But, you know, it is a really nice, sharp knife.
The knife comes with care instructions that emphasize the the brittleness of the blade to lateral forces: don't knck the edge against anything hard, don't smack the flat of the blade to crush garlic. No dishwasher.
The special care is a small price for having such a unique knife in the kitchen!
