Gramur

Gramur in Norse mythology, was the famous sword of the, hero Sigurd. It was the most excellent that had ever been made by dwarfs. Sigurd proved it in two ways: he cut in two a large piece of steel, and, behold, the sword had not even the slightest scratch; then he laid it in the river, which carried a light woolflake against it, and the latter was cut in two.
