Like Vulcan, you wield the power of fire. Blacksmiths are a pretty physically powerful bunch. It takes a lot of muscle to pound metal for hours using a hammer, so much so that your arms are bound to get a little Thor.
Not to say that there aren’t quite a few ladies who get into blacksmithing. According to the British Artist Blacksmiths Association, they boast 20 female blacksmith members out of 700. Talk about womanpower.
