> The industrial revolution rendered a lot of traditional blacksmith work — making hammers, nails, axes, shovels and more — obsolete. But blacksmiths like Mr. Kaviar, 69, have found success creating so-called “functional art.” Mr. Kaviar, for instance, is regionally known for making handrails forged with leaves and birds that have a rough-hewed, borderline macabre design evocative of the work of sculptors like Louise Bourgeois.
You explicitly mention "horsehoes and nails", but I don't think that's a reasonable thing to expect: Especially for nails, I don't think many people would spend money on something that isn't really going to be visible. (I don't know enough about the farrier trade to say the same for horseshoes.) By contrast, a handrail is something that can be very visible.

very likely the hand-made ones are for restoration projects where you need to be as faithful to the original as possible.
or, more commonly in timber framing, rectangular profile.
Hammered in thin dimension between the grain, long dimension with the grain, maximising wood|metal surface area, minimising splitting|cracking forces.
So give they are using more or less the same methods of a blacksmith of yore and the etymology works, they would seem to be a blacksmith to me.

My totally unreserved guess is that there are not very many on a per capita basis, but there are probably about 10-50 working smith's per state. They do architectural work, historical pieces, education, sculpture, and all sorts of other stuff, if you include farriers (who deal with shoeing horses, but it's really a more technical trade that deals with horses gaits and health).
Nails are a whole 'nother kettle of fish: authentic forged nails are in (limited) demand for reproduction work. Cut nails and die forged nails (Tremont and Rivierre, respectively) are much loved at a more affordable price where absolute authenticity is a lesser requirement.
Incidentally, the surname Naylor is an occupational surname for a nail maker.
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.
Not to mention there's a whole bunch of functional-practical middle ground. The sword/knife people produce objects with usable blades but aesthetic qualities. Then there's literal gatekeeping: wrought-iron gates and fencing are both practical and aesthetic. Traditional in the UK although a lot got unnecessarily scavenged during the war.
