This Ossianic Ballad tells how Fionn MacCumhail and his men took Fionn's magic sword 'Mac an Luinn' to an enchanted smithy to be re-tempered. They followed a smith called Lonn Mac Lìobhann to the smithy, where there were four misshapen, four-armed blacksmiths, each with a claw-hammer and iron pincers. Some of the swords belonging to Fionn's men are named. These are 'Fead', 'Faoidh', 'Èigheach' and 'An Conallan'.
