I have often been annoyed when filleting fish in Norway on dull knives because just when filleting cod suffer all knives and even the more expensive. Sharpening stone and steel, and the knives were everything, but not sharp. Therefore, the Internet researched and found the Vulcan was needed! Fact which is as good as it is described and requires no great exercise. Already at the first attempt, the knives were sharp, whether hard or soft steel. Funtioniert properly and is easy to clean, but unfortunately do not come cheap!
