Maybe you do need at least one person who understands everything to oversee treatment but does the person who actually does the 12 hours of precision meat-cutting need to be that person? I don't know, it's just a thought. Master jewelers can do very fine work and handle lots of variation in the materials they work with but they don't need to know anything about the chemistry of gold in order to actually make the jewelry... They just need to know the right techniques and potential issues that can arise.
