Flying Swallow

Using 'Chakra Flow', this technique requires a bladed weapon; by feeding chakra into the weapon, the ninja will increase the length and density of his blade to strike an enemy from several feet out of the physical blade's range. This is accomplished by creating an invisible extension of chakra that shapes into an edge that functions like the normal blade itself.

Seeing the blade, the opponent may misjudge how far they need to move to avoid an incoming strike and thereby still be cut even if they manage to avoid the metal portion of the blade. The chakra-enhanced blades are strong and sharp enough to strike through solid rock or cut through iron. This technique works best with elemental chakra, especially with wind chakra for offensive cutting power.
