The smith felt the razor-edge of the bright weapon, and said, “This seems, indeed, a fair fire-edge. Let us make a trial of its keenness.”
Then a thread of wool as light as thistle-down was thrown upon water, and, as it floated there, Mimer struck it with the sword. The glittering blade cleft the slender thread in twain, and the pieces floated undisturbed upon the surface of the liquid.
“Well done!” cried the delighted smith. “Never have I seen a keener edge. If its temper is as true as its sharpness would lead us to believe, it will indeed serve me well.”
But Siegfried took the sword again, and broke it into many pieces; and for three days he welded it in a white-hot fire, and tempered it with milk and oatmeal. Then, in sight of Mimer and the sneering apprentices, he cast a light ball of fine-spun wool upon the flowing water of the brook; and it was caught in the swift eddies of the stream, and whirled about until it met the bared blade of the sword, which was held in Mimer’s hands. And it was parted as easily and clean as the rippling water, and not the smallest thread was moved out of its place.
Then back to the smithy Siegfried went again; and his forge glowed with a brighter fire, and his hammer rang upon the anvil with a cheerier sound, than ever before. But he suffered none to come near, and no one ever knew what witchery he used. But some of his fellow-pupils afterwards told how, in the dusky twilight, they had seen a one-eyed man, long-bearded, and clad in a cloud-gray kirtle, and wearing a sky-blue hood, talking with Siegfried at the smithy door. And they said that the stranger’s face was at once pleasant and fearful to look upon, and that his one eye shone in the gloaming like the evening star, and that, when he had placed in Siegfried’s hands bright shards, like pieces of a broken sword, he faded suddenly from their sight, and was seen no more.
For seven weeks the lad wrought day and night at his forge; and then, pale and haggard, but with a pleased smile upon his face, he stood before Mimer, with the gleaming sword in his hands. “It is finished,” he said. “Behold the glittering terror!—the blade Balmung. Let us try its edge, and prove its temper once again, that so we may know whether you can place your trust in it.”
And Mimer looked long at the ruddy hilts of the weapon, and at the mystic runes that were scored upon its sides, and at the keen edge, which gleamed like a ray of sunlight in the gathering gloom of the evening. But no word came from his lips, and his eyes were dim and dazed; and he seemed as one lost in thoughts of days long past and gone.
Siegfried raised the blade high over his head; and the gleaming edge flashed hither and thither, like the lightning’s play when Thor rides over the storm-clouds. Then suddenly it fell upon the master’s anvil, and the great block of iron was cleft in two; but the bright blade was no whit dulled by the stroke, and the line of light which marked the edge was brighter than before.
Then to the flowing brook they went; and a great pack of wool, the fleeces of ten sheep, was brought, and thrown upon the swirling water. As the stream bore the bundle downwards, Mimer held the sword in its way. And the whole was divided as easily and as clean as the woollen ball or the slender woollen thread had been cleft before.
“Now, indeed,” cried Mimer, “I no longer fear to meet that upstart, Amilias. If his war-coat can withstand the stroke of such a sword as Balmung, then I shall not be ashamed to be his underling. But, if this good blade is what it seems to be, it will not fail me; and I, Mimer the Old, shall still be called the wisest and greatest of smiths.”
