Sharpening a Ceramic Knife

This video demonstrates how to sharpen a ceramic knife using the Work Sharp Knife and Tool Sharpener. A ceramic knife is made from Zirconium Dioxide, also called Zirconia. It is much harder than steel and will stay sharper longer than most steel, but is also brittle and can chip or break. Diamond abrasive belts in two grits, #180 and #1500, are used in sharpening this knife. Only diamond is harder than ceramic, so only these diamond belts will work.

only ignorant people use ceramic knives
steel knives are more versatile, easier to maintain & sharpen, more reliable.
and steel knives can stay sharp (actually sharper) just as long as a ceramic

Good video….. It was nice to see those diamond belts go to work. I know they don’t recommend the diamond belts on steel, but I wondered if maybe you have given it a try? I think it’s most likely due to the aggressiveness of the diamonds.

Zirconia goes through a phase change when force or heat is applied, therefore it is good to use cooling when working on zirconia. The different phases of zirconia have different sizes and changing phase puts a strain on the material.
