There are three categories of wooden implements that are not intended to serve as containers: a) Any wooden implement that is made solely for human use, e.g., a ladder. It is pure. It is not susceptible to impurity at all, nor did our Sages decree that it should be included among the implements susceptible to impurity. b) Any wooden implement that is made to be used for other implements and by a human, e.g., a table, a counter-top, a bed and the like. They are susceptible to ritual impurity. How is it known that they serve both a person and his accessories? Because one places plates on the table, cups on the counter-top, and spreads on the bed. c) Any wooden implement that is made solely for the use of implements; thus it serves entities that serve man. If it only serves other implements during the time work is being performed with them, it is entirely pure, e.g., a wooden candelabrum that serves a lamp while it burns. Similar laws apply to an implement placed under an implement while it is being used and all molds. If, however, it serves implements during the time work is being performed with them and when work is not being performed with them, they are susceptible to ritual impurity. Examples of such implements are: the covering for a box and the like; a sheath for a sword, a knife, a spear, scissors, a razor, a spoon used for blue eye paint, or a stylus used to write; a well used to store blue eye paint; a case for a writing tablet or a leather placemat, a carrier for arrows, a case for wide arrows, and a case for flutes. All of these and anything like them are susceptible to impurity even though they are only used to serve other implements. The rationale is that they are necessary for the implements both at the time work is being performed with them and also when work is not being performed with them. There are, by contrast, other somewhat similar implements that are pure, for example: the covering for a wardrobe, the covering for a chest, the covering for a basket, a carpenter's press, a chair placed under a chest or a domed covering for it, the mold over which a leather covering for a Torah scroll is made, a wooden covering for a door bolt, or the covering for a latch or a mezuzah, a case for lyres and harps, a bust on which the makers of turbans wrap that head-covering, a mold on which tefillin are made, a wooden horse used by a singer, rhythm sticks used by mourners, a sun-shield of a poor man, support beams for a bed, the pillars of a bed, and a board used as a support for a bed. All of these and implements like them are pure, because they serve other implements only when they are being used.
