So I was poking around my antique store finds, and decided to pry the old used blades out of an empty pack to see what they were. I found some gillette blue blades and one craftsman DE blade. I didn't realize craftsman made DE blades. My first thought was that it was for a hand tool rather than a razor, but the old owner ran out of blades and made use of the craftsman. Does anybody have any info about old craftsman DE blades?
