How do you sharpen a ceramic vegetable pealer?
Ceramic knives and vegetable/fruit peelers:- They are made of an advanced, high-tech ceramic called zirconium oxide (also called zirconia). This material, which is second in hardness only to diamond, was originally developed for industrial applications where metal components failed. Zirconium oxide is extremely hard, wear resistant, and chemically inert. Zirconium oxide has a hardness of 8.2 mohs (vs. steel at 5-6 mohs and diamond at 10 mohs)Unlike traditional steel cutlery, ceramic knives and vegetable/fruit peelers generally do not need to be sharpened at all.
to sharpen any ceramic utensil it must be sent back to the manufacturer. there are no sharpening devices made to sharpen ceramic, you will only ruin it. i had to send my ceramic pocket knife back to the manufacturer to get sharpened twice not because it got dull but because the knife's edge chipped, they have a special diamond dust coated wheel
