Barrow Blades

Barrow Blades
The Barrow Blades are daggers, or short swords, forged in Arnor in the middle of the Third Age. They are red in colour, with "flowing characters of Numenor" inscribed on them. They will/do not rust, as long as they are all kept in their sheaths, and all of them are "wrought with spells for the doom of Mordor". The Barrow-Blades are found by the hobbits in the barrow of a barrow-wight and given to them by Tom Bambadil. The sword that Frodo was given breaks in the confrontation with the witch-king on the banks of the river near Rivendell and it is replaced by the sword Sting. Sam, Merry and Pippin all keep their swords. Merry's Barrow Blade plays a superbly important role in the Battle of Pelennor Fields. It is enchanted with the power to harm the witch-king himself by a weaponsmith of arthedain long before. This blade, when stabbed into the witch king, broke the spell protecting his undead flesh, and crippled the witch-king, giving Eowyn of Rohan the chance to kill him.
