Another 2nd Dan Hapkido technique, this one is very difficult to do. The takedown with the sort of "half nelson" is what most students are unable to do when reaching second dan, so definitely most civilians trying it for the first time won't be able to do it either. It requires a reasonable development of "aiki": flow. Nonetheless, it's not bullshido, it's simply a high level skill that takes discipline and practice to learn. Not the same thing; only ignorants say otherwise. The pin is very uniq
