Thin, soft wires, e.g.. ties made of annealed steel or of non-ferrous metals are easiest to straighten in a device made of a wooden board with embedded nails. Nails should be hammered in along the undulating line. We weave a bent wire between them. If we keep dragging him, pulling e.g.. combiners, it will be thoroughly straightened when scrolling between nails. Both short wire lengths can be straightened in this way, as well as whole scrolls. Too thick wire cannot be straightened.
