conditions are these permitted?
(b) Rebbi Elazar ben Tadai is more lenient than the Tana Kama.

such a needle Tahor (because it is no longer considered a Kli)?
(b) According to Rava, if a broken Kli has lost its status regarding
Tum'ah, it has also lost its status regarding Shabbos. How then, does Rava
explain the difference (stated clearly in a Beraisa) between Tum'ah and
Shabbos - in this regard?

According to Abaye, they are: 1. 'a K'li she'Melachto le'Heter le'Tzorech
Gufo'; 2. 'A K'li she'Melachto le'Heter le'Tzorech Mekomo'; 3. a 'K'li
she'Melachto le'Isur, le'Tzorech Gufo' - all with one hand only; 4. 'Kol
