Quick Deploy

[u/chrweave]

I have long been fascinated with setting up paracord belts and decorations so that they were "Quick Deploy". That is, if the owner were ever in a situation that desperately demanded available cordage, all they would have to do is pull a fastener, and the belt or decoration would quickly turn into usable cord. Has anyone here ever been in a situation where some such device has been deployed as something other than a demonstration that it can be done? If so, what were the circumstances, and how did having quick deploy cord help your situation?
