Shime no Dan: Itokiribasami Chizome no Nodobue

is a technique of Shunsui Kyōraku's Bankai, Katen Kyōkotsu: Karamatsu Shinjū.

Description
While Sandanme: Dangyo no Fuchi is active, Shunsui sheathes his swords and winds a white thread around his opponent's throat multiple times. He then pulls it taught, creating a large gash. The cut area will then expand and explode, effectively destroying their head in the process.
