Bisection (両断, Ryōdan) is a simple, but extremely effective Samurai technique that is only used by skilled practitioners of the Samurai Sabre Technique. Using one's innate control over chakra, they super-condense the chakra flow to the point where it seems like another metallic layer has been placed on the blade. This dramatically increases its cutting potential, especially against larger opponents. Through timely release of this chakra as thin, sharp waves, the user is capable of increasing their cutting range to cut multi-story opponents such as Tailed Beasts with relative ease.
Additionally, this technique can inadvertently provide defensive properties to the blade, thanks to the metallic layer acting as reinforced metal, which, when applied to a defensive situation, provides a large venue of opportunity for the user. This is most evidently seen in the use of shockwaves emitting from the blade, which are brought about from the timely release of chakra, repelling any weaponry used against them.
