The Irish ordeals, Cormac's adventure in the Land of Promise, and the decision as to Cormac's sword (Author: Unknown)

section 59

Socht had a wonderful sword, with a hilt of gold and a belt of silver: gilded was its guard, diverse-edged its point (éo). It shone at night like a candle. If its point (rind) were bent back to its hilt it would stretch (back again) like a rapier. It would sever a hair (floating) on water. It would cut off a hair on (a man's) head, and without touching the skin. It would make two halves of a man, and for a long time one half would not hear or perceive what had befallen the other. Socht said that that it was the Hard-headed Steeling, Cuchulainn's sword. They held this sword to be a tribal bequest (?) both of fathers and grandfathers.
