Yes the "Opening of the Mouth and Eyes" ceremony used a tool shaped like a constellation it was made of meteoric ion. I think it or any meteoric iron in general was referred to as "Ra's semen" or something like that. It is an adze but I don't even think it has a name or at least nothing in English other than adze. I've seen it described as simply "nw" or "stp". Many ancient languages didn't use vowels.
