good, also this attack can be used to (if you have a doujutsu, or a HELL of knowledge on the human body) to stun your opponents muscles without penetrating or simply stabbing them. Yeah, stabbing sounds better. Unless you're planning a sneak attack, but meh. If you can actually land a chidori senbon attack you'd use it to stab.
SOOOOOOOOOOOOOOOOOOOOOOOOOO
Simply perform a chidori and wave it in front of you as you release all of its electrical essence and manipulate its shape into various, sharp, two-tipped needles. A single chidori should produced tens of needles. The technique is easy, chidori, release, compression into multiple senbons, release. Try to hit all of this mini kankuro dolls!
