Hi there folks, new member here. Apologies if this topic has been covered before now, and also for the length of the first post...
OK so, a little bit of background for context.
I'm a martial arts instructor and practicioner, I've been studying traditional Japanese jujitsu for almost ten years now, and my current rank is nidan second degree black belt. I am currently working towards my next grade, sandan third degree black belt, which brings me to my point and question. As part of my ongoing learning I now need to learn some knots which may have been used by the Samurai of old. The Samurai were lawmen as well as warriors and being an insular nation, there were no shackles used on prisoners. They were tied using differing knots and types of cord, depending on the person's social status. So for instance a governor would be tied differently to say, a farmer, should either be found to have broken the law.
So, I'm trying to figure out some knots which would be able to be made in-line on a single length of cord which is around 6m in length, which could bind wrists etc, but could be quickly and easily released. For verification that I'm not some nut job I can direct you to the Facebook page for the Scottish jujitsu society where I train 😊
