There is another older one also to I can't find again yet has some good Micro-Graphs
"Two types of razor blades were used to establish a standard that could be used tocompare blades produced in these experiments. The first blade was a Gillette doubleedged stainless steel blade produced in the early 1980s, when double edge blades werestill used in disposable razors. Figure 7 presents SEM micrographs of this blade in the 3orientations discussed for Fig. 1. Analysis of the edge width (EW) was done at 3 randomlocations along the edge at magnifications of 3000 to 10000x and values of EW varied onaverage between 0.35 and 0.45 microns (µm). "
There is the part on DE Blades Looking for the Old stuff on the SR's
