Try your best not to drop a ceramic knife. Unlike metal knives, ceramic blades are extremely brittle and can chip or break if handled too roughly.
Double check that the electric sharpener is for ceramic blades, as the sharpening mechanism is different from metal knife sharpening tools. There are ceramic knife sharpeners that run on batteries or are manual. These are similar to using an electric sharpener; just make sure they’re designed for ceramic knives.

Keeping the knife’s blade between a 16- and 21-degree angle follows the natural curvature of the blade. [9] X Research source Be gentle when applying pressure on the blade. Ceramic knives are extremely brittle, and too much pressure could cause the blade to snap or crack. [10] X Research source
Sharpen each side 6 times. Counting each drag of the blade can help you keep track. [12] X Research source
If your file doesn’t come with a holder, use your non-dominant hand to hold the blade at a 20-degree angle.
Ceramic knives are very brittle, so use gentle pressure when filing to avoid chipping or cracking your knife. [18] X Research source
