A question for the old timers(or any timers), have any of you demolished an older house that had a safety razor disposal slot built into a bathroom medicine cabinet? Was dealing with the dispised blades any more difficult than usual?

    Since your restricting answers to old timers I'll just comment that they fell to floor and I swept them up. No problem. Commented May 16, 2021 at 14:27

  • As a child I always imagined there would be millions of blades back there, but in the half dozen or so i've explored, there's usually none or a few dozen max.

  • There's a cute (ancient) SciFi short story where this problem is solved by installing a gadget in the back of every medicine cabinet that sends the used blades "elsewhen." Commented May 17, 2021 at 18:43

1 Answer 1


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.

    Thanks Ed, I had thought through the caution part but hadn't realized the need to consider safe disposal.

    +1 for the magnet. I place a piece of cardboard, (think cereal box) between the magnet and the blades. Slide the cardboard off the magnet and you have a no contact release.

    I think you mean WW1; a cat's whisker crystal set. They had mass-produced superheterodyne receivers by WW2...
