When I empty my trailer of scrap metal at the scrap yard I always see old spanners like in the image at the top just lying on the ground but I don't pick them up ,unless it's a Victa spark plug tool ,last time I was emptying the trailer there were these two pullers on the ground so I naturally took them home but I am guilty of throwing out old spanners like the ones above when buying a toolbox from a swap meet .
