Chigiriki

The chigiriki is a more aggressive variation of the parrying weapon kusarigama.

The iron weight could have spikes and its shape could be round or be multi sided.

Chigiriki belong to the furi-zue family of weapons (brandishing-sticks),[3] which include any type of stick or staff with a chain attached.

It is also one of the shinobi-zue weapons (concealed staffs and canes), which were often hollow and had multiple uses, such as hiding other weapons like shuriken, or as a blow gun or breathing tube.

[2] The method of training in the use of chigiriki is called chigiriki-jutsu (契木術).
