apparently people can put chakra into weapons (temari can put chakra in the wind, the rain ninja used chakra in the needles to guide them, gaara had chakra-imbued sand, etc.)

but...can anyone do this with ANY weapon?

like i dont see why they just dont guide their kunais at each other...or something

or like whenever they throw weapons, it would just follow their oppoents...

confusing...?

maybe it takes up too much chakra, but i dont know, needles arent that much smaller than kunai.
