Safety Razor Disposal in Medicine Cabinet
Many homes had the slot to drop used razors into. I use a magnet to pick up the old razors. Even rusty they can be sharp.
I used to wrap them in a newspaper so they would not cut through the trash bags.
Today I would probably put them in some cardboard because we always have Amazon boxes to recycle.
If you find old Gillette razor blades, the coating on the blades makes a makeshift diode if you want to experiment and make a WW2 radio out of a coil of wire, an ear bud and razor blade - or that’s what my dad said. I was a sparky and we were told to rip out components, but that probably would only work on Hogan's Heroes.
