I was writing a question about working with iron, and noticed that there seemed to be quite a lot of tags relating to the topic, some of which seemed conflicting:
I don't have the score needed in any of these tags to suggest synonyms (and probably wouldn't do so without asking on meta anyway), but I think they could probably use some cleaning up.
I'd suggest keeping metals and metalworking, making forging a synonym of the latter, and getting rid of iron. It seems forging is almost always used with metalworking anyway, and I don't see it adding too much.
Is this something that should be cleaned up?
