The base of smiths is tamei. But that of a blacksmith is tahor. A sharpening board that has a receptacle for [holding] oil is tamei. But [a sharpening board] that does not have [a receptacle] is tahor. A ledger that has a receptacle for [holding] wax is tamei. But [a ledger] that does not have [a receptacle] is tahor. [Regarding] a straw mat or a straw tube, R’ Akiva rules it tamei, but R’ Yochanan ben Nuri rules it tahor. R’ Shimon says: The same applies to colocynth. A mat of reeds or of sedge is tahor. A reed tube that was cut for the purpose of being used as a receptacle is tahor until one removes all of the pith.

[Regarding] a bin, Beis Shammai say: It is measured from its interior. But Beis Hillel say: It is measured from its exterior. Both agree that the thickness of the legs and the thickness of the rims are not measured. R’ Yose says: They agree that the thickness of the legs and the thickness of the rims are measured, but [the area] between [the legs] is not measured. R’ Shimon Shezuri says: If the legs were one handbreadth high, [then the area] between them is not measured. But if not, [the area] between them is measured.

[Regarding] its wheel, when it is removable, it is not [considered] connected to [the bin], it is not measured together with [the bin], it does not protect [against tumah] together with [the bin] when [they] are an ohel over a corpse, and we may not drag it on the Sabbath when there is money inside it. But if [the wheel] is not removable, it is [considered] connected to [the bin], it is measured together with [the bin], it protects [against tumah] together with [the bin] when [they] are an ohel over a corpse, and we may drag it on the Sabbath even though there is money inside it. [Regarding] its cover, when it is [permanently] set, it is [considered] connected to [the bin], and it is measured together with [the bin]. But if it is not [permanently] set, it is not [considered] connected to [the bin], and it is not measured together with [the bin]. How is it measured? [By drawing] a diagonal line. R’ Yehudah says: If [the bin] cannot stand by itself, it is

A bin, a chest, and a closet that [have had] one of their legs broken off, even though they [can still] contain, are tahor. And if they cannot contain in their usual manner, R’ Yose rules [them] tamei. The poles of a bed, [its] platform, and [its] covering are tahor. The only tamei [parts of a bed] are the bed [itself] and the malbein. But the malbeins of the Levites are tahor.
