People often ask: can you sharpen ceramic knives? Well, you certainly can! But don’t use that old sharpening rod or triangle that you use for your steel knives. It is not recommended, as it may chip the blade and ruin the knife.
So, how do you sharpen a ceramic knife?
Manufacturers oft recommend sending ceramic knives to professionals for sharpening. Which you can do. Brands like Kyocera even offer free lifetime sharpening (though you may need to pay for transport costs).
However, you can sharpen the knives yourself at home. (Always check the warranty to make sure that you are not voiding it by sharpening the knife yourself.)
You use a similar technique to that practiced on steel knives, but for ceramic knives, it’s essential you use a diamond coated surface, whether it’s a sharpening stone, file, rod or another sharpening system.

#2. Kyocera Advanced Ceramics Knife Sharpener Review
With this item, there is a roller assisted guide to help you to control and aid precision sharpening.
The beauty of this item is that there is no mess, as the grinding dust is contained within the safety cover.
Though some would consider it a convenience (like with outdoor activities), a downside some is that the unit runs on batteries (4 × AA) — not included in the package, loses power over time. Using high-quality rechargeable types can help with the replacement issue.Click here to see the latest price on the Kyocera Advanced Diamond Knife Sharpener
#3. Barbestar Knife Sharpener ReviewWhat’s good about this 2 stage diamond coated sharpening design is the large handle (and it’s price). It sits flat and sturdy on the bench and has a slot specially designed for ceramic knives (fine grade grinding). The other slot (coarse) can be used for steel knives, including fishing, hunting, and pocket knives.
How? Insert your ceramic knife into the ‘fine’ grade slot and pull the knife through the slot from heel to toe with proper and uniform intensity, repeating this action 3-5 times. Always clean the knife with water and let dry before use.
Possibly the best buy for the price…Probably not suited to your most expensive ceramic knives, however. It is best to spend in line with the expense of your knives and your budget, of course.Click here to see the latest price on the Barbestar Knife Sharpener
