Perhaps just carrying a couple of handcops would be a good middle of the road.
Essentially it's the outer sheath of paracord with an extremely strong Technora cord on the interior. Light weight and should be enough I reckon. As opposed to carrying metallic handcuffs around, not like I was set on the idea just exploring. I made my own couple of handcops, one made with just technora cord by it's self and another which had a 400lb breaking strain core of technora inside a paracord sheath. That should be fine and they fit nicely into the MOLLE webbing of my pocket organiser where I carry EDC items.
Probably way less chance of causing injury too with them being soft in all areas.
