So many Red Imps!

I was just looking at the Classifieds, and it looks like there are at least 3 Red Imps for sale that have different manufacturers. Some were made in Germany; I have a Red Imp 133 blade that was made in USA by Case.

So what gives with Red Imps? How does one razor have so many manufacturers?
