The HORL®3 Pro is a high-precision rolling knife sharpener built for serious users who demand speed, versatility, and control. This model introduces a built-in planetary gear mechanism speeding up sharpening - each rotation yields results three times faster than previous versions. It offers six selectable grinding angles (10°, 13°, 15°, 20°, 22°, 25°), letting you fine-tune the edge for delicate blades or tougher steels. The sharpening system uses a diamond grinding disc for efficient metal removal and a ceramic disc to hone and refine the edge, while a "Quick Lock" system makes changing discs fast and tool-free. The upgraded grip pad ensures stable contact with the blade during use, and the overall design is engineered to deliver professional-level sharpness with reduced effort.
