Ceramic knife

Suzie Mar 30, 2007 04:46 AM

Does anyone have an opinion out there on them? I would like to buy one but there seems to be so many in the market place. I am a little hesitant about buying one on line ( I like to see how it feels in my hand) but at least I could start with some research on ones that are recommended.

    They are a fun "add-on" to have, though not a necessity. If you already have good quality knives for the basics (chef's knife, slicing knife, paring knifes) and have filled a need for specialty items (fillet/boning knife, cleaver) it is a fun high-tech addition. The edge on some is like a scalpel, and the super smooth surface can give an almost lubricated feel to certain kind of cutting tasks.

    I have had a ceramic peeler for over five years and it still peels like new, a ceramic grater is probably almost as old and it too has not dulled a bit. I have had a santoku for about two years and it is basically a 5 and half inch long razor...

      I do have a great set of knives but I LOVE gadgets so I am sorta looking at this addition more as a cool gadget (slicing tomatos etc) but I want to make sure I invest in a good one. Thanks for all your help!

        I have 4 ceramic knives and love them. The oldest is 5 years old and still slices tomatoes paper thin. My knives are Kyocera. The chef knife is my workhorse.

      I've owned two, both received as gifts and I did like them, the inability to resharpen them myself and the relative fragility of the blade edge eventually relegated them to the back of the collection. I think I'd spend my money on a really good conventional knife I'd worry less about.

        I love going to visit my mother in law just to slice tomatoes with her ceramic knife. I haven't found one I like anywhere near me, but I keep hinting so hard to her that I really like how hers works and wish I had one.

        She smiles and ignores me a she hands over another tomato. :)

        By all means, get one. They shouldn't NEED sharpening if you take good care to store it, cut only certain things (veggies, let's avoid de-boning or such), and store it properly.

          Suzie, don't do it. It's impossible to sharpen at home and while the manufacturer will resharpen it for you, it's a pain to wrap it up and send it in because the blade is so fragile. That being said, I have a Kyocera 6" Santoku and I like it. The coeffiecient of dynamic friction between the blade and what you are cutting is lower than it is for a metal knife. In other words, the side of the blade is naturally slippery so it appears to cut more easily.

            They can be easily sharpened with diamond bench stones.

              Really? Is that the way you do it?

                I didn't think that was possible??

                  Diamond is harder than ceramic. You have to finish with very light pressure on a high grit to avoid chipping the blade.

                  looks like my edit didn't work...

                  what I meant to say in my first post is just that diamond easily removes material from the edge... HOWEVER getting a fine finished edge is trickier than with a steel knife due to chipping.

                  testing another edit here...
