We just talked about that last night, how when we were kids we had to scrounge rusty used nails and straighten them all before we started a project.
I usually scrounged them out of Dad's shop.
I remember it well. A 6" deep, thick cardboard box about 10"x10" filled with a mixture of nails. Every nail known to man was in that box. I can't remember the amount of times he needed nails and I had to run into the woods to find the box at the last fort I left em in. Usually found his hammer he needed right next to it as well.
