The final form of the Force Edge blade in which the legendary sparda used. The Force Edge can only be upgraded to its final form by combing Dante and Vergil's amulets together by Defeating Nelo Angelo (Vergil) the third time. The main reason it was upgraded to its final form in the game is because it is supposed to be used to defeat Mundus. During the fight with Mundus you get the Sparda's devil trigger only on this Mission in the whole game. It can kill a Marionette in 2-3 hits and can be kept in your second playthrough of the game.
