Hi, I found the Sharpening of Wüsthoff an Internet knife test. Since I do not umbedingt 40 - - 60 - wanted to pay euros for a good steel, I have decided to Wüsthoff steel. So, I have already tried some steels; but the steel of Wüsthoff is just great. Exactly where did I searched for. Highly Recommended. Greeting Hans-Gerd
