Nuibari

The Nuibari is one of the swords of the Seven Swordsmen of the Mist, wielded by Kushimaru Kuriarare. It's a longsword in the shape of a large needle, with a long thin wire that resembles thread tied to the eye. This sword is said to pierce all and stitches them together. It is able to pierce multiple targets at once, and stitch them together in bundles. The user can throw the needle to pierce a line of enemies, then catch the needle at the other side, and then repeat at different angles to create knots with the wire passing through the bodies, effectively creating bundles of bodies at different points in the wire.

The sword was first seen in the manga when a revived Mangetsu Hōzuki, who mastered the use of it, summons it with a scroll which then he returns it to an also revived Kushimaru.
