These strings are constructs made from very concentrated chakra so, they can be seen by people besides the user. Interestingly, as well as pulling objects towards them with the strings, the user can also "push" objects away from them as well, and even get moving objects like buzzsaws. Chakra can also be transferred via the strings, such as to activate some abilities in puppets. The chakra strings can also be attached to other objects, allowing the user to control, or at the very least disrupt other things. In one instance, Kankurō uses chakra strings to trip Naruto Uzumaki when they first met. In another, Chiyo uses chakra strings to control a person like a puppet. A skilled user can suppress the chakra to the point that the strings become invisible, as Chiyo did with the Manipulating Attack Blades to sneak a string to bind Hiruko's iron tail. Kankurō has shown the ability to attach his chakra strings to those of another user's. This technique is limited to one main string per finger for normal humans, but Sasori's modified core was able to emit enough strings to control over one hundred puppets.
