The following are unfinished metal utensils: anything that will be smoothed with a file, have its surfaced leveled, have its uneven points scraped away, be polished, be pounded with a hammer, or is lacking a handle or a rim. Such a utensil is not susceptible to impurity until it was finished and beautified to the extent that no work is required for it at all. What is implied? A sword does not contract impurity until it has been smoothed, nor a knife until it has been sharpened. Similar concepts apply with regard to other comparable acts. Accordingly, when one makes utensils from a block of iron ore, a bar of metal, or the iron surface of a wheel, from plates, from the coverings of utensils, from the base of utensils, from the rims of utensils, from the handles of utensils, from metal scrap removed from utensils or pieces cut away from utensils, they are pure. For all of these are considered as unfinished metal utensils. If, however, one fashions a utensil from broken metal utensils or from utensils that have worn out over the course of time, or from nails that were made from utensils, these are susceptible to impurity, because they are not in an unfinished state. If, however, it is not known whether nails were made from utensils or from blocks of iron ore, they are pure. Even if they were formed into a k'li, they are not susceptible to impurity.
