This is an ability a jinchūriki is able to perform when in a tailed form. In the series, Naruto used this technique multiple times, without it being named, in different tailed forms. Naruto varied the chakra arms' use from grappling hooks, to either grab onto objects or enemies from great distances, to offensive means, as merely touching one of these can cause fatal burns, due to the Nine-Tails' seething hatred within its chakra. Due to having chakra attached to his body, the chakra arms can grow in size and from the fourth tail up, Naruto, the arms, or any part of his body can divide into two or more fully operational appendages. Killer Bee has also been shown to use this technique though instead of arms, he can form horns which he uses for his Lariat technique. Killer Bee could also physically create the arms and the Ox's tentacles to restrain an opponent.
In his Nine-Tails Chakra Mode, Naruto can use the chakra arms to its fullest extent, as it has the strength to crush stone with just a grip. After some practice, he mastered the arms, able to manipulate various stones and geometric shapes without crushing them. Now he is able to use them in an attempt to create a new jutsu, the Tailed Beast Rasengan since he can't use the Shadow Clone Technique in his Nine-Tails Chakra Mode.
