I appreciate the idea but it has to be slow and cumbersome to unravel the bracelet when you need cordage. Seems like a lot of work for a little bit of useful material. And I very much dislike jewelry. I wear a watch but that's about all I can tolerate. Back when I was married it was very difficult to get used to wearing a ring.

This might be heresy but I'll say it nonetheless- paracord is a bit overrated. It's great stuff but pretty bulky for the length. It's not really very usable as rope and overkill for most uses of cordage. Don't get me wrong, I love the stuff and use it quite a bit. But for survival/emergency uses I think bank line is better. It's very strong but much less bulky.
