This set is ideal for sharpening kitchen and outdoor knives, based on a standard sharpening process with a 1000 / 6000 combined waterstone. Includes the KME base, which allows one-handed working. With the stone thickness compensator, you can easily even out abrasives with different thicknesses, so that the same grinding angle can be kept throughout the sharpening process. The included Sinensis camellia oil protects newly sharpened carbon-steel blades against rust. It is also food-safe, so you can also use it for kitchen knives.
