Telchar
From Tolkien Gateway
Telchar was a Dwarf of Nogrod in the Blue Mountains, and one of the greatest smiths in the history of Middle-earth. Among his works were Angrist (the knife that freed the Silmaril from the Iron Crown), Narsil (the sword of Elendil, later reforged for Aragorn as Andúril), and the Dragon-helm of Dor-lómin.
