HORL is a German brand behind the popular rolling sharpener, which makes it easy to keep your knives sharp – without years of training on a whetstone. With a fixed 15° or 20° sharpening angle and diamond-coated sharpening discs, you maintain the edge quickly and consistently. HORL is the perfect complement to the whetstone and an obvious choice for anyone who wants to avoid dull knives without compromising on results.
