I just came across this site, a medical supply company, that offers what appears to be high quality razor blades that fit many razors, including some very old fashioned ones, DE's, injectors, straights, etc.
You can see the site here: http://www.emsdiasum.com/microscopy/products/preparation/blades.aspx?mm=8
