I reached out to Dovo Solingen the makers of the famed Merkur Vision 2000 razor and learned that the only difference between the Merkur Vision and the Merkur Vision 2000 is the name. They explained that the same razor has been marketed with the 2000 in some areas but in other areas the 2000 was left off. I would leave it at that but I have seen others explain that there is a difference between the original Merkur Vision because it has a set screw which disappeared in later models. Can anyone direct me to the history of this DE? Thanks!
