This is how to tie (or weave) a simple rope chain. This is done very loosely because if I do it tightly, you will not be able to see past my fingers.
Next, a very easy, simple, practical way to make a rope-weight for practicing kusarifundo safely with another person. Based on a hangman's noose.
Next I show how to make a different type of rope-weight for safe practice, then show how to apply the rope chain. This can be done with both rope-weight styles.
