At some points in history smithing - especially the working of iron - possessed a certain amount of mystique, at least partially due to the complicated and mysterious techniques a smith had to learn to make decent products. Also, in cultures where iron was a sovereign protection against the fair folk - or equivalent powers, the smith, who worked iron all the time, was seen to have special immunity. This sort of quasi-mystical status can be found in dark ages Europe and pre-colonial Africa amongst other cultures. In many legends it will be the smith who lays The Devil - or an equivalent malicious trickster - on his anvil and hammers him into surrender, combining brute force and iron in a traditional response to the supernatural.
That said, smithing is also a "hat" for a variety of legendary and fantastical species - dwarves are probably the most famous, but in some treatments various kinds of giant and even goblins have been known to smith in various metals as well.

- weaponsmith - produces metal weaponry of many varieties and styles

As demonstrated by "phlebotinumsmith" you can pretty much put the suffix "smith" behind anything to create a neologism meaning "the person who makes or repairs that", "the guy who makes that out of metal", or "the person who bashes and shapes that". So, expect your standard fantasy setting to have a mithralsmith, magicsmith, etc.
