Когда человек перерезал горло [животному] серпом, острым кремневым камнем или тростником, это Кашер. Все могут зарезать в любое время и любым инструментом, кроме крюка для жатки, пилы, [острых] зубов [животных, зафиксированных в верхней челюсти], или ногтем пальца, потому что [первые три упомянутых] делают не резать, а душить [и рвать]. Когда человек зарезал животное с помощью жатки, имеющего зубы или зазубрины, только с первым или ударом вниз или только порезом, это непригодно для использования в соответствии с Бет Шаммай, но Бет Хилель считает его Кассером; но если зубы жатки были заточены (чтобы дать ему острый и ровный край), это то же самое, что нож.
Tosefta Chullin
And similarly as to a blind person that knows how to slaughter, his slaughter is valid (Hul. 1:1). A minor that knows how to slaughter, his slaughter is valid (ibid.). We can always slaughter, whether during daytime or nighttime, whether on a boat or on top of a roof. We can slaughter with anything (Hul. 1:2), even with a flint, even with glass, even with the point of a reed. We can slaughter with anything, whether with something connected to the ground, or whether disconnected from the ground, whether, the knife is passed on top of the throat, and whether the throat is passed on top of the knife and slaughtered, [and] his slaughter is valid.

Tosefta Chullin
One who flays the skin of an animal [by pulling it from the feet toward the neck (see Jastrow, "מרגל")] and [then] slaughtered [the animal], his slaughter is valid. A detached tooth or a detached fingernail -- we may slaughter with it (Hul. 1:2). A scythe [may only be used to slaughter] by [cutting] in the direction it normally traverses (alt., moving it forward) (ibid). Beit Shammai invalidate it and Beit Hillel validate it. And if the teeth of the scythe are filed away, behold, it is like a [regular] knife. One who [intended to] stick a knife in the earth by throwing it [באַטְלֵק not באטלס, see Jastrow] and slaughtered with it, his slaughter is invalid. A knife that has many notches (lit., "notches notches"), behold, that is like a saw. If there is between one notch and the next notch [a space equivalent to the space] between the two [simanim] in the neck, his slaughter is valid. [If] there is but a single notch, if it would get caught, the slaughter is [nonetheless] valid, [but] if it strangles, it is invalid.
