Kyocera 5.5-in. Ceramic Santoku Knife, Pink  Product Reviews

"I've been using this knife frequently for over a year now and it is still razor sharp and the first knife I reach for whenever I cook. Ceramic knives do have some problems though, the first is that they are fragile. I broke my first knife in half when the tip got stuck in a peach pit and I tried to pull it out. The other problem is that they are extremely light, so not good for say, butchering a whole chicken. This is NOT a heavy duty knife. But when cared for and used properly, no steel blade can slice cleaner or faster than these Kyocera ones. Also remember that these knives can't be sharpened. Their cutting edge last 10x longer than steel ones but they have to be sent back to Kyocera to be sharpened, don't try to hone them either."

"I absolutely adore these Kyocera knives, they are the sharpest things I have ever seen. I ordered this through Witbecks, and the first one got lost in the mail -- that can always happen. When I contacted Matt Witbeck he responded immediately (that night, from home) and the next day sent me a replacement. I have never had such prompt and unquestioning customer service, and so I want to recommend Witbecks to anyone."
