I am a metalsmith by trade, though I've only done a tiny bit of blacksmithing. Not too much casting either as I find I prefer working more directly with metal. My training is more jewelry oriented though I don't do much jewelry either. I scaled up to hollowware, mostly decorative vessels. What I'm doing was more commonly termed silversmithing, though I work predominately in copper. I still do a silver piece from time to time.
Metal is a wonderful material! I often compare it to really stiff clay in the way it can be moved around. If you are into in metalsmithing you might find
this section of my website interesting. In it I documented the making of one of my pieces from start to finish.
Here's some of what I do.
