(…) but Túrin begged Orodreth for a sword, and he had not wielded a sword since the slaying of Beleg, but rather had he been contented with a mighty club. Now then Orodreth let fashion for him a great sword, and it was made by magic to be utterly black save at its edges, and those were shining bright and sharp as but Gnome-steel may be. Heavy it was, and was sheathed in black, and it hung from a sable belt, and Turin named it Gurtholfin the Wand of Death; and often that blade leapt in his hand of its own lust, and it is said that at times it spake dark words to him.
