Then grunts and goes in, with a slam and flick
To beat real iron out, to work the bellows.

from Seamus Heaney – The Forge on Rap Genius

Meaning

The blacksmith is seen as resolved yet tiresome; showing how his blacksmithing is a main routine in his life, working with the “bellows” (a chamber that blows air) and beating “real iron” described as a slam and flicks of light. The poem ends in this image to show that a person occupation can be a natural way of life.
