Depending on the quality of the steel, every knife will become blunt at some time, so it has to be sharpened. The sharpness of Nesmuk knives can be maintained for a very long time with the help of the Nesmuk strop. However, even the most resistant blades can become so dull due to hard contacts, lateral sliding over cutting pads or excessively long care intervals that you have to remove a little more material from the cutting edge in order to get the blade sharp again. We have developed the Nesmuk sharpening stick precisely for this purpose. In most cases, conventional sharpening sticks have relatively coarse grinding wheels that roughen the surface of the cutting edge too much during sharpening.
