The unpredictable fantail of sparks
“The unpredictable fantail of sparks” describes how long the black smith has been working as his job profession. Being a blacksmith, shifting metal has certain qualities. Such as when the sparks fly.
His notice of the sparks can symbolize how the sparks seem never-ending; there are too many of them. This could also be shown as his life in the blacksmith profession. Never-ending, and unpredictable.
