I don't work as fast as some as I feel using premade bar stock for handmades is a short cut. I like to smelt and cast may own bars at the horse then turn the handmade bars into handmade shoes. I generally use iron ore from a gemstone pit near my house in order to use hand-dug iron to make into the handmade steel barstock.
I don' t work 'on' any, but I do work 'under' a fair number. So far this year, I've worked on one turkey, but that was a two man job so I don't know if it counts. If we consider any given horse a "pig to work on/under" does it count as a horse, a pig, or both?
