For those not confident using a whetstone, let us introduce the HORL 2 PRO knife sharpener. The HORL 2 PRO is not only easy to use; it requires no soaking and gets the perfect angle every time. This advanced model has a planetary wheel mechanism that lets it work 3x faster than the HORL 2. You can sharpen to 15 or 20 degree angles. The 15 degree side for Japanese knives and the 20 degree side for western knives. Each sharpener comes with a diamond grinding disc and a ceramic honing disc (with the Premium Sharpening Set also available as an extra which includes interchangeable #3000 and #6000 discs with a leather finishing strop). The HORL 2 PRO comprises of two parts: a magnetic angle support bar and the roller which houses the discs. To use, the knife is placed upside down against the support bar and held in place by strong magnets, the disc roller is then rolled up and down the length of the blade. For smaller knives you will place the knife higher on the support bar so the sharp edge of the knife will always be touched by the roller. The roller and support bars have a dark bronze aluminium finish and are manufactured in-house by HORL in Germany’s Black Forest region. Care – keep both the sharpener and the angle support dry. You can clean the diamond grinding disc with an eraser to remove dust or for larger deposits, soak the surfaces in a hot water bath with dishwashing liquid and remove with a brush. The diamond steel disc will become less coarse after approximately 20 uses; this is intentional, and works as intended in subsequent uses
