From what I understand, there are two or more types of Wilkinson blades. I have only used the black case ones from Germany. They are great blades maybe not the smoothest, but I did enjoy using them and would be happy to use them again. To give my comment some context - I would only consider repurchasing about 50% of the blades that I have tried thus far.
