Power

You wield the power of fire. But then again, so does Granny Smith every time she strikes a match and lights the candle by her bedside.

The truth is, blacksmiths just don't have a lot of power (those immense Thor-like biceps aside). Blacksmiths are artisans, and no—not the "inspire people to reconsider philosophy, government, and religion through the wonders of artistic expression" kind of artist. 

That said though, if you can figure out how to spark intellectual revolution through little more than the curve of your nineteenth-century table mounting, then more power to you.
