The knife sharpener can be reached only moderate sharpness. Some of my knives were less sharp than previously after treatment with the AnySharp. My previous sharpener branded Herbertz worked on exactly the same principle, but I got here a far better sharpening result. In addition, the AnySharp takes a disproportionate amount of material from the knife blade away, so for expensive knives already utterly unsuitable. Therefore, may be issued for the AnySharp not advise!
