The Blade Dodge is a Combat move in Batman: Arkham City, Batman: Arkham Origins, and Batman: Arkham Knight. The move is used against enemies equipped with sharp objects (Thugs with Knives or Broken Bottles, or Assassins with Swords) who attack with multiple swipes in quick succession. The Blade Dodge is an extension of the normal counter move to a series of attacks. The player holds the Counter button and moves away from the enemy to dodge every swipe.
Releasing the counter button in between each swipe performs a Blade Dodge Takedown that knocks the enemy out instead (Upgrade required).
