Dáinsleif

Dáinsleif ("Dáinn's Heirloom" ) is king Högni's sword, according to Snorri Sturluson's account of the battle known as the Hjaðningavíg.

When Heðinn offers him compensation for the abduction of his daughter, Högni replies:

"Thou hast made this offer over-late, if thou wouldst make peace: for now I have drawn Dáinsleif, which the dwarves made, and which must cause a man's death every time it is bared, nor ever fails in its stroke; moreover, the wound heals not if one be scratched with it."
