# One shouldn't use a scythe or even a double edged knife if one side of it is a scythe. Bediavad if he did it and knows he used the kosher side, it's ok, and if he smoothened out the scythe side then he can use it lechatechilah.<ref>Simla Chadasha 6:2</ref>

# A knife cannot have any nicks in it or be used previously with non-Kosher food or for idolatry. It must not be glowing hot or attached. ''See [[Knives That Cannot Be Used for Shechitah]] for details.''

===Detached From Its Source===
# Anything sharp attached to the ground or a body may not be used for shechitah until it is detached.<ref>Simla Chadasha 6:5</ref>
# If it was detached and then reattached, one still should not use it regardless of whether he plans to leave it there (which would render the meat prohibited due to the Gemara's uncertainty) or not (which would be invalid on a rabbinic level). If one's intention is unformulated, we can determine based on context.<ref>Simla Chadasha 6:5</ref>
# An animal's jaw with sharp teeth may not be used, as the gaps between teeth are the same as nicks in a knife, but a singly tooth attached to a jaw is fine. Even a single nail on a severed foot would be ok. Some argue that if it's still attached to a whole limb, such as a whole jaw or whole animal foot, that would be considered "attached" to its source of growth.<ref>Simla Chadasha 6:6</ref>
