Скачать или смотреть Chullin 18a: The Slaughter Knife s Law

The sugya details the legal requirements and consequences surrounding ritual slaughter (shechita), focusing heavily on the mandatory inspection of the slaughterer’s knife by a scholar. Early discussions differentiate between penalties for disrespecting the scholar (which warrants ostracization) versus using a flawed knife (which results in the slaughterer’s removal and the meat being declared non-kosher). This authority is demonstrated in a case where Rav Ashi performs a judicial review, overturning a previous ruling after confirming the slaughterer’s knife was intact, thus declaring the meat acceptable despite concern for the original judge's honor. Furthermore, the tractate explores the permissibility of various non-standard tools, such as a detached tooth or fingernail, clarifying that they are valid only if they do not rip the tissue, and are not attached to a living source. Lastly, a disagreement between the schools of Beit Shammai and Beit Hillel concerning the use of a serrated harvest sickle is presented, noting that both agree the item is permitted once its edges are smoothed.
