HORL 3 Rolling Sharpener - The Original
Simple yet professional knife sharpening – with the HORL 3 Rolling Sharpener. The tool, whose name sounds as unspectacular as a tool from the hardware store, has revolutionized the topic of "knife sharpening" since its inception. No prior knowledge or practice is necessary for sharpening with the HORL 3 Knife Sharpener. With the HORL 3 Knife Sharpener, you can start right away, and your knives will be gently and efficiently resharpened.
The two-part tool of the HORL 3 Rolling Sharpener consists of the actual knife sharpener and the magnetic sharpening guide. This sharpening guide uses its extra-strong neodymium magnets to fix the knife at the perfect angle to the rolling sharpener during the sharpening process. This allows the knife sharpener to be guided precisely along the knife edge at all times. Only a correct and consistently maintained sharpening angle leads to a good sharpening result and is one of the main factors for successful knife sharpening.
The rolling sharpener itself has two sides: a diamond disc on one side and – depending on the model – a stainless steel or ceramic disc on the other side. The fine-grained diamond disc gives the knife a smooth and sharp edge. By honing with the stainless steel or ceramic disc, the blade is subsequently smoothed, and the burr is removed. The original HORL leather strop made of genuine cowhide ensures a perfect finish after the sharpening process.
The HORL Rolling Sharpener is available in various versions, from the basic model to the masterclass. The HORL product family also includes various interchangeable sharpening discs, stylish docking stations for storing and presenting the HORL Rolling Sharpener, a storage box, the HORL Magnifier – a magnifying glass for sharpness checking – and the resharpenable HORL Scissors.
The Origin of the HORL Rolling Sharpener
The classic knife sharpening method with a whetstone is indeed the royal road, but it requires technique and practice. The desire to find a new solution for the challenge "sharpening knives" drove the inventor Otmar Horl in the mid-90s to develop a suitable tool. The resulting first HORL Rolling Sharpener was consistently further developed by Otmar and Timo Horl, the founders of the Freiburg family startup company, in the following years. This was followed by the HORL 2 and the HORL 2 Pro, the latter already with a gear planetary drive.
In the fall of 2024, the beginning of a new era: The HORL 3 Rolling Sharpener hits the market, showcasing a new design, scoring with new features and new sharpness.
HORL block diamonds in the HORL-3 series provide up to 80% more material removal during sharpening, for even faster honing and a more consistent sharpening pattern. The new HORL Grip Pad with up to 70% more grip ensures that even small knives are better fixed to the sharpening guide.

The Functionality
Simply put: The HORL Rolling Sharpener ensures the high-quality sharpness of your knives. Period. And the handling is extremely simple. Thanks to the ingenious friction wheel drive, only the grinding discs rotate while you securely hold the handle roll and focus on guiding the rolling sharpener.
In the HORL 3 version, you have two different discs available for sharpening: The diamond-coated grinding side with a grit of #400 removes material from the blade and restores the sharpness of the knives. On the opposite side is a ceramic honing disc with a grit of #1000. This fine grit ensures less material removal and simultaneously polishes your knives.
Each 2-piece set includes the magnetic sharpening guide. This varies depending on the model (please see the detailed product description above). With the 20° sharpening angle, knife blades receive stable sharpness for daily use. The 15° sharpening angle provides a delicate sharpness for very fine blades made of high-quality Damascus steel or carbon steel. Strong neodymium magnets and a grip pad securely hold the knives during the sharpening process, regardless of whether the knives have a wide or narrow blade.
The Accessories
Since the diamond grinding side might be too coarse for very finely ground blades, HORL also offers accessories for these special blades. Instead of the regular grinding discs, the optionally available corundum grinding discs with grits of #3000 and #6000 can be quickly and easily screwed on. For a razor-sharp edge, we recommend the Kagami ceramic grinding disc with a grit of #9000. These grinding discs are especially recommended for Japanese knives. Additionally, there is a HORL leather strop made of genuine cowhide with a rough and a fine side for the final polish.
How to Sharpen with the Rolling Sharpener
In short, very simple and foolproof. Find a flat surface like a countertop, a cutting board, or a table, place the knife with the spine down on the surface, and attach the sharpening guide approximately in the middle of the blade.
Now hold the handle firmly and place the rolling sharpener on the blade. Then push the rolling sharpener back and forth with light pressure. Make sure that the entire edge is sharpened, all the way to the tip. Repeat the same procedure on the other side, and you're done.
We can't answer the question "How often?" from a distance. It depends on how dull or sharp your knives were before and how finely you want to polish them. Normally, a maximum of 10 movements is more than sufficient.
