I wouldn't be surprised if the ebay sellers noticed that some razors were making alot of money (much more then they picked them up for at the estate sales where they buy them for resale) and decided to start picking up more razors and selling them. I saw something similar at an antique mall that I go to occasionally. When I was going there alot and picking up straight razors, the number of razor kept increasing everytime I went back. Unfortunately, so did the price.
