[Tolkien]Is Sauron a particularly skilled blacksmith?
gpt
Sauron used to work for Aule, the god of smithing and crafting who created the dwarves. Even after leaving the service of Aule for that of Morgoth, the first Dark Lord, he remained an incredibly powerful and skilled craftsman. Others who learned from Aule include Saruman and the Noldor, one of the three kindreds of high elves.

The crafting of "magical" items in Middle-earth is really a combination of two factors: the skill to create an artifact, and the personal power to put into its creation. When the elves of Lorien make rope or cloaks, they're not doing anything fundamentally different than what an ordinary person would do - they're just more skilled and able to create a better end product, to the point of being supernaturally effective. Things like the Rings of Power or the Silmarils are examples of the same thing, but with much greater power and skill put into their crafting.
