§ Of the Sindar The Silmarillion

At this time therefore the Sindar were well-armed, and they drove off an creatures of evil, and had peace again; but Thingol's armouries were stored with axes and with spears and swords, and tall helms, and long coats of bright mail; for the hauberks of the Dwarves were so fashioned that they rusted not but shone ever as if they were new-burnished. And that proved well for Thingol in the time that was to come.
