[In] three cases [concerning tumah susceptibility], R' Tzadok rules [that the articles can become] tamei and the Sages rule [that they are] tahor: (a) the nail of a money changer, (b) and a grist-merchant's chest, (c) and the nail of a sundial; R' Tzadok deems [these three capable of becoming] tamei, but the Sages rule that they are tahor.

There are four things that Rabban Gamliel deems capable of becoming tamei and the Sages deem tahor: The metal cover of a householder's teni, and the hanger of a strigil, and unfinished metal utensils and a tray that split into two. But the Sages agree with Rabban Gamliel in the case of a tray that split into two [pieces], one large and one small, [that] the large [piece] is [capable of becoming] tamei and the small [piece] is tahor.
