Windmühlen sharpening rod "Corundin"

Sharpening

Draw the cutting edge of the knife across the sharpening rod from the bolster to the blade tip. For our knives manufactured using the ”Solingen-Dry-Fine-Grinding®“ process (hand-sharpening method used in Solingen), 2 to 3 strokes on each side of the blade are perfectly sufficient. Try to use the whole length of the ceramic rod. The cutting edge should be placed on the ceramic rod at an acute angle. You will hear whether the cutting edge is in proper contact with the rod through a gentle, sandy sound and you will feel how the blade “engages”. The sound of the cutting edge contacting the rod may neither be scratchy nor overly smooth. Do not use too much force – it is better to repeat the sharpening process in order to achieve the desired result.

Cleaning

As with all ceramic materials that are used for sharpening, a little bit of steel – which is abraded from the blades – remains on the rod. This causes the ceramic surface to become too smooth and the sharpening power therefore decreases. With the rod in a wetted state the supplied abrasive-eraser can be used to easily remove the steel deposits, just like using a rubber eraser. The sharpening rod is then fully ready for use again

Repairability

Should you ever drop your sharpening rod and the ceramic becomes damaged or broken, you can send it for repair. In contrast with other sharpening steels, the ceramic element of the Corundin® sharpening rod can be replaced, thereby saving costs and conserving materials.
