HORL®3 knife sharpener, walnut

The HORL®3 sharpener is an innovative and simple way to sharpen knives. Made in Germany. 

Otmar Horl originally conceived of this knife sharpening method in 1993. The Horl sharpening system has two pieces: a magnetic angle support and a rolling sharpener. The magnetic angle support features a 15° sharpening angle for Japanese knives on one side, and a 20° sharpening angle for Western knives on the other. The rolling sharpener has two abrasives, a diamond grinding disc and a ceramic honing disc. The newly developed assembly design incorporating ball bearings give it a smooth rolling feel.

To use Horl, put the magnet on a flat surface, hold it in place with one hand for stability and stick a knife on the angled side you want to use. Next, set the roller on the counter next to the knife blade roll the coarse abrasive slowly along the edge of the knife. Next, remove the knife, flip the magnet around and attach the knife so the other side of the blade is facing out. Finally, repeat the process with the ceramic side of the roller. The whole thing takes about four minutes per knife.
