durandal (fire emblem)

A legendary sword in Fire Emblem: The Binding Blade and Fire Emblem: The Blazing Blade.

In FE7, the sword is Eliwood's exclusive weapon and the titular "Blazing Blade".

Fun piece of historical trivia: the legendary sword on which this one was based was ostensibly the same one wielded by Hector (of Troy, not that other one.)
