Wusthof Two Stage Knife Sharpener
The blade is guided precisely thanks to the pre-set angle of the carbide and ceramic slats. Sharpening is easy even if you are not used to it. The ergonomic shape of the handle and the non-slip base ensure comfortable and safe handling. With this sharpener, the knife is simply drawn through the guiding notches a few times - the coarse side is used to sharpen blunt blades and should only be used on the dullest knives, while the fine notch is more gentle and can be used with a little more frequency on moderately sharp blades.
