Грабли пепла, у которых был удален конец лопатки, подвержены загрязнению, так как они похожи на молот: слова раввина Меира. Мудрецы объявляют это чистым. Пила, пропускающая все остальные зубы, чиста. Но если сохранилось m'lo hasit [расстояние между растопыренным большим и указательным пальцами] последовательных зубов, оно подвержено загрязнению. Поврежденные предметная поверхность, скальпель, самолет или дрель подвержены загрязнению. Если его стальной край отсутствовал, он чист. Во всех этих случаях, если он был разделен на две части, обе [части] остаются подверженными примесям, кроме сверла. Блок самолета сам по себе чистый.

English Explanation of Mishnah Kelim
An ash-shovel whose spoon was missing is still susceptible to impurity, since it is still like a hammer, the words of Rabbi Meir. But the sages rule that it is clean. The ash-shovel is used to rake out coals from an oven. According to Rabbi Meir even if the shovel was removed, it is still susceptible because its heavy iron body is still usable as a hammer. Although this was not its original use, it still has some use, this use is sufficient for it to remain susceptible. The other sages hold that since it can no longer be used for its original purpose, it is no longer susceptible to impurity.

English Explanation of Mishnah Kelim
A saw whose teeth are missing one in every two is clean. But if a hasit length of consecutive teeth remained it is susceptible to impurity. If one out of every two teeth is missing, the saw is no longer susceptible to impurity, because with so many teeth missing, it is no longer usable. However, if a hasit (some say that this is the length between the forefinger and thumb and some say between the forefinger and middle finger) length of teeth remain in one place, then the saw is still usable and is still susceptible.
