Not the best quality video, but hopefully it is still useful. Harry Asher published the simple simon knot in 1989 and I've only come across it in a fairly limited set of publications. It is similar to a square knot but holds better in synthetics, doesn't come apart if it is bounced around a bunch, doesn't weaken the rope nearly as much as a sheet bend, and can be used to join cordage of different thicknesses. Perhaps this is all old news to everyone here, but maybe someone will find it useful.
