With this sharpener I paid 8.50 euro on amazon I sharpens my knives with ALL REAL sharpening razor. My big Chef of professional knife. My bushcraft knife Mora robust. My table knives. My opinels. My Laguioles. My tactical hunting knife thick blade. The blades are smooth or toothed (serated). And of course my 3 Swiss knives. It sharpens absolutely everything as a razor. It does not seem to wear yet. I trained before with a piece of saw blade I sharpened into a knife blade. Well I got to shave with! A truly amazing sharpener made in germany.
