This device is an "electric water-cooled" blade sharpener that can sharpen various blades, including kitchen knives, knives, scissors, carving knives, and chisels. The main unit measures approximately 12 cm wide × 18 cm deep × 8 cm high. It weighs about 840g, making it small, lightweight, and easy to handle. The grinding wheel rotates at approximately 210 rpm. The grinding wheel uses aluminum oxide (grit #400). Compact and lightweight — Its small width and depth make it easy to place in a home kitchen or workspace, and it's easy to put away after use. Because it's a water-cooled type, there's less worry about annealing the blade like with dry grinders, allowing you to sharpen while maintaining the blade's hardness. This is generally considered an advantage of water-cooled sharpeners.
