The Durandal is a weapon in Final Fantasy XII. It is the strongest one-handed sword in the original version, and only obtained as the Well-forged Blade in the Bazaar. In the Zodiac version, the Well-forged Blade is instead the upgraded Durandal, the Simha. Stronger than both of these are the Great Trango and the upgraded Masamune, Kumbha, which is in effect a one-handed Katana.
Durandal has a sprite.
Durendal is a holy sword in The Song of Roland, an old French literary piece. The sword is said to contain within its hilt one tooth of Saint Peter, blood of Saint Basil, a hair of Saint Denis, and a piece of the raiment of the Blessed Virgin Mary. It is said to be able to cut solid boulders in half with a single strike.
