This sharpener is an extremely effective accessory to restore an impeccable edge to all your knife blades, especially those of high-hardness closing knives. This sharpener has 2 sides. The first side is intended to make a roughing with a coarse grain (#360), the other allows you to finish the work with a fine grain (#600) for a perfect result.
For best results, keep the machining slopes of the original sharpening.
