Remember those old medicine cabinets with a slot cut out in the back? Yup, I had to open up a wall behind my bathroom sink (the old galvanized pipes have had a long and useful life, but like all things are coming to an end), and found some old double-edged razor blades on top of a board. You'd think maybe there'd be a box or something to catch the blades but nope, just let them pile up.
Amazingly hardly rusted at all for sitting around for decades!
