What a good edge looks like

How the Knifemate Excels

The problem with sharpening ceramic knives is that ceramic blades are very brittle. Ceramic has a hardness of 9.5 (as opposed to steel with a hardness of 6.5). If you apply too much pressure to the side of the blade, it could easily snap. Also, the only material hard enough to sharpen ceramic is diamond, with a hardness of 10.

When you are sharpening ceramic, a burr will not form when you’ve reached the proper point on the edge. When sharpening a steel knife on a stone, you can sharpen it until you feel the burr by running your finger in the direction of the blade. Without the burr forming, it may be difficult to know when you’ve completed the task.

Hints & Tips

 If your knife is dull, we suggest you to start with the medium grit stone.

Colour the edge of the knife with a felt-tip pen. You can check your progress in sharpening and the angle the knife by observing where the colour is removed.

Start by laying the blade flat on the stone, raise the blade spine approximately the thickness of the blade, and start moving the knife in circular motions.

After restoring the edge to the original shape, de-burr the edge lightly with the diamond stone in order to get a razor-sharp edge.

Serrated edges

The Common Problem

To sharpen a serrated knife edge, consider doing so with a round sharpener or a similar style stone. Lay the diamond shaft in the serration and file up and down in each serration along the entire blade.

When sharpening of a serrated blade is sufficient, a burr can be felt on the flat, or reverse side of the knife blade (you can feel the burr with your fingernail). This burr should be removed by rubbing that side of the knife with the Diamond Knife Sharpener with a circular motion. If no burr appears, then the angle was too small and the work on the grooves must be repeated using a larger angle.
