Is this product suitable for sharpening ceramic knife blades?

I have a Boker ceramic knife. I did use the Duosharp to sharpen mine and it will definitely sharpen the knife. Is it the recommended way? Don't know. My instructions tell me to send the knife back to Boker to be sharpened. Brian

I would not recommend this! Most ceramic knives are zirconium dioxide, which is a very hard material. Unfortunately the product does not specify what carbide the course blade is, but the cheapest carbides fall above zirconium dioxide in hardness, so I'm guessing the coarse side would work for you. But the fine side with the ceramic inserts is almost assuredly zirconium dioxide as well, so you will be scratching both the knife and the sharpener, making the sharpener nearly useless pretty quickly on the one side. That said, as long as you stay with the course side and are careful, you could still make a ceramic knife sharper.

Should be fine. Those are steel blades and 16 degree angle, which is what this sharpener is for.

I have not tried to sharpen any ceramic knives and don't know if the reviewer is correct. If this is true my guess would be that the ceramic is as hard or harder than the grinding wheels in the sharpener. In most cases ceramic is very hard but brittle that's why ceramic holds an edge longer than steel but breaks or chips if side force is applied.

Yes, I do. I originally bought this to sharpen some of the Henckel knives I have, but used it on others that were not as expensive and it worked great!

Will not sharpen a ceramic knife. A ceramic knife is not able to be resharpen it is a ceramic not metal

Here's what the instructions say. "Use on alloy, carbon, or stainless steel. Not for scissors, serrated electric knives and any blade that does not fit freely in the guides." No mention of ceramic. I will say it has sharpened everything from a large cleaver to the most thin fillet knives. Hope this helps. I still give it a 5.

I have no idea. I sharpen mine on a normal knife sharpener with carbon tip blades. any normal knife sharpener would work. I sure would not use a ceramic knife sharpener. I love the knife.

I do not know, because I don't own those type of knives. However, the instructions indicate that this sharpen can be used to sharpen this type of knife.

It's not recommended. Officially, ceramic knives must be sent back to their producer to be sharpened at the factory. Fortunately, this service is typically cheap or even free.

no grooves, they're not needed when using a ceramic sharpener. this thing is a beauty: it can be used to sharpen serrated knives, such as bread knives, or slicers. on conventional knives, just use it as you would a conventional steel with grooves.

No, the sharp edge of the scissors usually is more than 45 degrees (some times near 70 degrees), and this tool has an angle of 15~20 for carbide and 30~35 for ceramic. If you are a very skilled person, you could use the rod. But for me it is not a good solution.

I don't know for certain. This sharpener works with the knife blade perpendicular to the ceramic discs. It would be impossible to sharpen the serrations of a serrated blade.

This is a pretty small knife sharpener. I use it to sharpen orchid shears. I would think you would want a little longer "stone" to sharpen knifes

Should be fine. I don't own any ceramic knives, honestly. But I'd say if you took it nice and slow and didn't crank the belt speed all the way you should probably not have any problems. Also be careful with the lower grit belts as they take off a lot of material.
