Congratulations on your good shave and your good razor find. I'll give you the same advice a fellow gave me about collecting tobacco pipes many years ago. Go slow until you learn a little bit about what you are doing. It is easy to let the RAD take over and get a bunch of stuff you won't be happy with or be able to get your money out of.
If you go to
this part of the razor forum you will get an idea of what razors forum members hold in high regard. In the Wiki at the toolbar above there is a section on razors to avoid. I will let you look around and find that. Lots more good info in there while you looking. :tu
