how many here remember the medicine cabinets with a razor blade slot? my younger brother who is a professional carpenter was remolding a house that was built in the 50s he tore the bathroom wall out and to his surprise the wall had a ton of old double edge razor blades in it. him and the home owner was stumped how they got there? he told me and I knew at once how they got there. the old cabinets had a slot to dispose of the old double edge blades. the old blades went behind the cabinet into the wall, I told him I grew up using one. I still shave with a double edge razor but my early 1900s medicine cabinet don't have the slot, I have to throw them in the trash,,,,,,,,,,,
