Nuibari

The is one of the swords of the Seven Swordsmen of the Mist, wielded by Kushimaru Kuriarare.

Overview
The blade itself assumes the form of a narrow that greatly resembles a large needle, with a long length of thin wire-mirroring thread, tied through the eye located at the base of its hilt. This sword is said to possess the ability to pierce all and stitch them together, demonstrated through its ability to effortlessly penetrate multiple targets in a single thrust and then quite literally stitched them together in substantial bundles, by simply pulling the attached wire taut. A capable user can even throw the sword with the intent of piercing a line of multiple enemies, before catching the needle at the other side and repeating the process at different angles, in order to create knots of corpses with the wire passing through the entirety, effectively creating bundles of bodies at various points along the length of the thread.

The sword is first seen when a reincarnated Mangetsu Hōzuki summons it from a scroll, where it is then returned to Kushimaru, and last seen in the anime when Kushimaru is sealed.
