Sure thing Mr. Xylon-sensei!
Futon, otherwise known as Wind Release is one of the five basic elements in this world. We can grasp the wind easily if we try to sharpen our chakra and to make it as thin as possible. Because of this, we can infuse our Wind Chakra into weapons like Kunai to make them sharper and more precise when thrown. Wind-based Jutsu is also more appropriate for short-mid range attacks so that it is much easier to control the sharpness of the wind, and so you can slash through your opponents with it.
Wind is naturally strong against Lightning-based attacks, since it is a natural insulator. Also, it is weak against Fire-based attacks since wind can act like a fuelling agent for the fire, and it spreads faster. Wind is also used for other aspects of Jutsu, such as making Ice, which is really only needed for members of the Yuki clan, and also used for Dust Release, which is mostly used by Onoki, the Third Tsuchikage.
Did I bore you yet?
