Chakra Flow refers to any technique that increases the potency of a weapon by flowing chakra through it. Usually, elemental chakra is used to flow through bladed weapons to increase the sharpness dramatically. Wind chakra is usually used to increase sharpness, but lightning also provides vibration that can produce the same effect, as well as inducing numbness.

Asuma Sarutobi carries special Chakra Enhanced Trench Knives that absorbs chakra easier to create unique effects.
