It is a gradient, especially as blacksmithing becomes more prized for aesthetics. But that applies to a lot of metalwork. One common definition is that you're doing craftwork if the object is functional, artwork if it is functionally useless. I don't blacksmith, but I do machine things as a hobby. I consider most of what I do to be closer to the art end of the spectrum because I'm usually making it to explore the shapes, although there are frequently functional aspects. Is an overcomplicated umbrella stand of copper and bronze art or something else? Personally I'm still not sure.
