Cleaning out the attic we came across this object that the previous owners left.It looks like an old fashioned shoe stretcher. Coincidentally, I needed just such an item for my shoe. I have seen the later ones that are completely different from these so i am just guessing how these may work. The knob at the end confused me until I thought that it has to be hammered down fully to give the shoe the stretch...but its next impossible to do. Does anyone know just how these are suppose to work? Here are two photos of it.
