Ceramic blades can only be sharpened against something that is harder than it is. I would recommend sending it back to the manufacturer for sharpening if needed. Typically it is done using a very hard abrasive wheel because of the risk of the blade breaking, you do not want to do this without proper safety equipment. |

While ceramic knives will stay sharp for quite awhile, there is no such thing as "never needs sharpening". In our knife shop we use a diamond system that we developed to bring these knives back to their original sharpness. (or sometimes sharper!) One could try one of the diamond block type, sharpeners on the market but the ceramics are difficult to get the edge right. |

You can definitely sharpen a ceramic blade and do it by yourself. But due to the fact that the ceramic is super hard material you'll need more patience than with steel. Get a DMT or Lansky sharpening guide and diamond stones. You can use the diamond stones on either type of knife and the guides will keep you at the correct angle on both side of the blade. You can find several guides at this site http://www.sharpeningsupplies.com/Knife-Sharpening-Guides-C16.aspx |

Yes ofcourse Cary. Try using diamond steel, and check out this amazing video from Chef Phil for some more detauled instructions on how to do such. Hope it will help. |

Basically, no. Ceramic is super hard, harder than sharpening steels, and most sharpening stones. I guess diamond is harder, and you probably could sharpen on a diamond stone or diamond sharpening steel. But thats a very tricky skill to master, and a very delicate operation, not for the unskilled hand. The whole point in buying a ceramic knife is that you don't have to sharpen. With proper care ( e.g. Dont drop) it should last you a lifetime for home use. |
