A little bit of Hojo tonight.
This is is a blend of two rope purposes. The diamond tie is used to subdue more than transport. It is tight around the arms and neck so that, as your capture struggles, they slowly choke themselves out. So either they give up or pass out. Either way, they are subdued and you can move on.
The captor then ties the capture up for transport. This almost always included single column ties around both wrists, obscured by three chain stitch, and a chai. Stick lead to take up extra rope. The transport rope would not be done in a slightly more comfortable way, especially if you have a long way to travel. Single neck lines would cause too many problems over the journey.
Eh. Who needs to breath?
