In this instructable, I will be showing you how to make a very easy yet effective Kusari-Fundo or Manrikigusari. The Kusari-Fundo is a Japanese chain weapon used by Okinawans (the Okinawan variation of this weapon is called a Surujin) and ninjas.
This project was inspired by YouTube-er samurimaster500 and his YouTube video entitled "spike and chain wip" (I know its spelled wrong but that's the video's name. He's just not a good speller) in which he showed a makeshifht Kusari-Fundo that he made. So, credits for the original idea goes to him, I basically just posted instructions for something he made and tweaked it a bit.
