This made me immediately think of how old American homes in the back of the mirror cabinet of the bathroom just had a slot that fed into the space between the drywall so you could through your razerblades away. Good luck to the renovators in 50 years when they need to remove that drywall and pick up a thousand rusty butterfly-style razerblades. Can't throw those suckers in a plastic trashbag either cus it'll cut right through.
