חולין א׳Chullin 1

Mishnah 1א׳

הַכֹּל שׁוֹחֲטִין וּשְׁחִיטָתָן כְּשֵׁרָה, חוּץ מֵחֵרֵשׁ, שׁוֹטֶה, וְקָטָן, שֶׁמָּא יְקַלְקְלוּ בִשְׁחִיטָתָן. וְכֻלָּן שֶׁשָּׁחֲטוּ וַאֲחֵרִים רוֹאִין אוֹתָן, שְׁחִיטָתָן כְּשֵׁרָה. שְׁחִיטַת נָכְרִי, נְבֵלָה, וּמְטַמְּאָה בְמַשָּׂא. הַשּׁוֹחֵט בַּלַּיְלָה, וְכֵן הַסּוּמָא שֶׁשָּׁחַט, שְׁחִיטָתוֹ כְשֵׁרָה. הַשּׁוֹחֵט בְּשַׁבָּת, וּבְיוֹם הַכִּפּוּרִים, אַף עַל פִּי שֶׁמִּתְחַיֵּב בְּנַפְשׁוֹ, שְׁחִיטָתוֹ כְשֵׁרָה:

Anyone [may] slaughter - and his slaughter is valid - except for a deaf-mute, a shoteh [a person who exhibits signs demonstrating a lack of ability to think clearly], or a minor, lest they spoil the slaughter. But all who slaughter while others are watching them: their slaughter is valid. The slaughter of a non-Jew is a nevelah [an improperly slaughtered animal of a permitted species] and renders impure through carrying. One who slaughters at night, and so too a blind person who slaughters, his slaughter is valid. One who slaughters on Shabbat, or on Yom Kippur, even though he is liable for death, his slaughter is valid.

Mishnah 2ב׳

הַשּׁוֹחֵט בְּמַגַּל יָד, בְּצוֹר, וּבְקָנֶה, שְׁחִיטָתוֹ כְשֵׁרָה. הַכֹּל שׁוֹחֲטִין וּלְעוֹלָם שׁוֹחֲטִין, וּבַכֹּל שׁוֹחֲטִין, חוּץ מִמַּגַּל קָצִיר, וְהַמְּגֵרָה, וְהַשִּׁנַּיִם, וְהַצִּפֹּרֶן, מִפְּנֵי שֶׁהֵן חוֹנְקִין. הַשּׁוֹחֵט בְּמַגַּל קָצִיר בְּדֶרֶךְ הֲלִיכָתָהּ, בֵּית שַׁמַּאי פּוֹסְלִין, וּבֵית הִלֵּל מַכְשִׁירִין. וְאִם הֶחֱלִיקוּ שִׁנֶּיהָ, הֲרֵי הִיא כְסַכִּין:

If one slaughters with a hand sickle, a flint stone, or with a reed, his slaughter is valid. All [may] slaughter, they may slaughter at any time, and they may slaughter with anything, except a reaping sickle, a saw, teeth, or a finger nail, because they strangle. One who slaughters with a reaping sickle along the direction [of the teeth], Beit Shammai invalidates, but Beit Hillel validated. If its teeth were smoothed, it is like a knife.
