Kyoketsu-shoge

This is attached to approximately 10 to 18 feet (3–5 m) of rope, chain, or hair which then ends in a large metal ring.

Likely used by ninja of the Iga province, it is thought to be a forerunner to the later more widely known kusarigama (sickle and chain).

[2] Ninja were often recruited from the class of rural peasantry who resided on remote farmland, and the tool's resemblance to farming equipment and high versatility gave it many benefits in stealth combat.

The long range of the weapon combined a cutting tool along with the capability to strike or entangle an enemy at what the user perceived to be a "safe" distance out of the way.

When skilled with this weapon, it could be used to entangle a sword and pull it from an opponent's hands, rendering them harmless.
