The Energy Sword is a default starting weapon in Grifball. The Energy Sword can be used by either a normal melee or by using the right trigger to use a lunging attack. While it lacks the shockwave effect of the Gravity Hammer, it strikes much faster, and does not send other players flying away from you. By pressing the melee button at the correct time, you can parry a sword lunge. In Halo 4, the player immediately acquires the ball when the player kills the ball-carrier with an energy sword.
