Keilim 12:6-7

Keilim 12:6

There are four things that Rabban Gamliel rules susceptible to impurity that the Sages rule insusceptible: the metal cover of a homeowner’s basket, the hanger of a strigil (a type of blade), unfinished metal utensils and a tray that is divided into two sections. The Sages agree with Rabban Gamliel that if a tray is divided into two unequal sections – a large one and a small one – then the large one is susceptible to ritual impurity and the small one is not.

Keilim 12:7

If a dinar (a denomination of coin) became invalidated so it was modified to hang around a young girl’s neck, it is susceptible to ritual impurity. Similarly, if a sela (a larger denomination of coin) became invalidated so it was modified for use as a weight, it is susceptible to ritual impurity. A sela can depreciate for up to two dinar (half its value) and be retained for use as a weight; if it depreciates more than this, he must cut it up (so that it won’t be used inadvertently as a coin).
