I read from time to time, on this forum and others, about counterfeit DE razor blades. Is that even a thing? Considering the typical per blade retail price for these blades, the profit margins have to be so (pardon the pun) razor thin, that I can't imagine it could be very lucrative. Maybe for feathers since they tend to be pricey for a DE blade, though I'd think knockoff cartridge razor blades would probably be the way to go.
