The Mishna rules that "one may always slaughter." Raba and Rav Yosef both understand this to refer to the period of Exile, but each explains it according to a different Tannaitic view - either Rabbi Yishmael or Rabbi Akiva. These Sages disagreed over whether the Jewsl in the desert were forbidden to eat meat unless it was brought as a sacrifice, or whether they were permitted to eat meat even without formal ritual slaughter (shechita). After delving into the debate between Rabbi Yishmael and Rabbi Akiva and resolving various difficulties raised against each position, the Gemara challenges the explanations of both Raba and Rav Yosef based on the textual context of the Mishna. Ultimately, the Gemara concludes that the phrase "one may always slaughter" includes even a Jew who eats non-kosher meat l'teavon (out of appetite).

The Gemara then analyzes which specific types of nicks in a knife disqualify a slaughter and render the animal a treifa, and which do not.

The Gemara outlines various customs regarding the method used to check the knife, alongside a debate concerning which parts of the blade must be examined.
