As long as the k'li can be used in a way resembling its intended task, it is considered as a k'li and is considered like a complete k'li. What is implied? A metal bucket that was broken but still can be used to draw water is considered a k'li as it was before. An urn is still susceptible to impurity if it can be used to heat water; a samovar, if it can contain selaim; a large pot, if it can contain metal pitchers; a metal pitcher, if it can contain perutot, wine measures, if they can measure wine; oil measures, if they can measure oil. When three holes, one next to the other, in the bottom of a strainer for mustard seed, were widened, it is pure, because it is no longer fit for its original task. When the hollow of a builder's shovel is removed, it is pure, even though it appears like a hammer, for it is no longer useful for its original purpose, but instead, as a hammer, and it was not made to pound objects as a hammer does. Similar laws apply in all analogous situations.
