Features of HORL Pro Knife Sharpener: Ex Works Finish The microscopic comparison is based on a high-quality Solingen standard kitchen knife ex works. Microsection HORL®3 Pro Corresponds to the result with the HORL® 3 Diamond Grinding Disc The industrial diamonds we use are suitable for efficiently sharpening all knife steels of any degree of hardness without water. When used properly, the HORL® Diamond Standard never needs to be replaced. The grain size of 46 μm grinds efficiently and precisely. A high-quality sharpening result achieved in just a short time. Ceramic Honing Disc After processing with the HORL® Diamond Standard, the ceramic honing disc significantly refines the grinding result. You need only a few movements for this. The result is a smooth, clean, and filigranely sharpened knife edge. Angles: 20° Grinding Angle For Stable Sharpness The 20° grinding angle delivers new sharpness in the shortest time. The knife also retains its sharpness for a long time due to the stable cutting edge and is suitable for the widest range of cuts in daily kitchen life. Outdoors, also provides many pocket knives with a stable cutting edge and excellent sharpness for everyday use. 15° Grinding Angle For Precise Sharpness With the 15° grinding angle, exceptionally fine blades made of Damascus and high-quality carbon steel attain filigrane sharpness. You can sharpen knife edges very delicately and maintain their stability. Superior Efficiency Industrial diamonds are considered one of the most durable and effective abrasives on the market. The monocrystalline diamonds are harder than any knife steel. By using a galvanic process, the diamonds in the HORL® Diamond Standard are fixed to approx. 55% in a nickel bed. After the first grinding process, the initially rough surface will become finer and the HORL® Diamond Standard reaches its ideal grinding surface. Timo and Otmar Horl, the father-and-son duo behind HORL 1993 had a singular vision: bring professional standards of knife sharpening to the home cook, simplified. What began at a home cellar is now a fully-staffed workshop in Germany’s Black Forest where every aspect of the manufacturing process is done locally, from steel melding to laser engraving.
