Difference between 一番鎚 and 親方 referring to a blacksmith in a fantasy novel


In a fantasy novel I am reading, a young blacksmith is referred to as "二番鎚",
which I think means 'apprentice'. Later, there is a reference to a "一番鎚(の大男)"
and a ”親方". I'd guess the former of these means something like "master
blacksmith", but the former also seems to mean "master" or "teacher".

Can someone describe the positions of these three roles so I can understand
their relationships?




(Copying comment)

親方 is a common word, but 一番槌/二番槌 are probably made-up words. You can safely
assume 一番槌 is superior than 二番槌, but I doubt you can generalize the
relationship between n番槌 and 親方.
