Episode Details

The Gemara continues the debate over whether shechita takes effect continuously from the beginning of the act until the end (yeshna l'shechita mitchila ve'ad sof), or if it only takes effect at the very final moment (eina l'shechita ela basof). Two further difficulties are raised against the latter opinion and are resolved.

There is a debate about whether the shechita needs to be done in a single, continuous cut (shechita mefura'at) or can be done in two or three different spots along the neck. The Gemara raises two difficulties against those who require shechita mefura'at. These challenges are resolved.

Rav Yehuda in the name of Rav brings a ruling about chalada, a disqualification of shechita when the knife is hidden under the simanim. The Gemara tries to assess what he is adding which wasn't already stated in the Mishna in Chullin 32a.

The second part of Rav's statement was that if the knife is under the hide, the shechita is valid. However, the beit midrash of Rav (Bei Rav) stated that it was unknown whether he actually permitted it under the hide. This statement by the scholars of his beit midrash led to several related questions that remain unresolved (teiku), such as hiding the knife under a cloth, under tangled wool, or concealing it during only a minority of the cut.

A Mishna rules that slaughtering two heads at once or two people holding a single knife and slaughtering are both valid. However, completely severing the head in one instantaneous downward blow is invalid due to pressing (drisa). The Mishna qualifies this: if the person was actually drawing the knife back and forth, but it came off after just moving the knife in one direction, if the knife was long enough, the shechita is valid. If they slaughtered with a back-and-forth motion, even if the blade is very small, the meat is kosher.

Two sources are brought to support the need for moving the blade back and forth when slaughtering.
