I was wondering if Hazal referred to the question of how exactly Abraham was planning to perform the שחיטה of his son Isaac. Clearly, Abraham had intended to do it as it is written "ויקח את המאכלת לשחוט את בנו".
In VaYikra we are given specific and detailed instructions on how שחיטה should be performed and those instructions vary depending on the animal or bird. In my Rosh HaShana's Machzor, I remember a passage referring to a Minhag of hiding away the Shofar in remembrance with Abraham hiding away Isaac so that the the satan won't inflict a mum (מום) on him (and thus making him inadequate for a korban).
I would appreciate the sharing of knowledge regarding this issue with sources.
