I have in mind to start a small collection of vintage razors. I don't have money to squander, so I'm looking for guidance on what to buy that is representative of countries and eras, without being ridiculously expensive. There seems to be, perhaps two or three books on the subject on Amazon, and nothing that I've found on this website. Surely the members that collect, have some guidance for the additions to their collections. I currently own only a Dovo Best 5/8" rounded. I'd want each collectable to also be in my shaving rotation. Where can I find information on what is and what is not, a desirable, moderately priced collectable razor?
