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. Telchar was trained by Gamil Zirak, another great smith. 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.
Etymology
The name Telchar resembles the Telchines of Greek mythology, a mythological race of divine craftsmen.
