I wondered about the price of the crucible tools too. They look amazingly made, and I'm sure they're a treat to use (they also look super cool), but at that price I just can't see myself buying a pair, and I'm terrible with my money when it comes to tools. I just can't see myself getting an extra $150 worth of divider from one.
I have a couple of the french dividers sold by Lee Valley and they are excellent and look very good (the brass/black combo is always attractive). I also have some vintage ones that are great too.
