No, but tell us how to make one with 2 rings for a keeper and I'll be your buddy.
I'll preface this by saying that I've tied tons of Paracord bracelets and even a leash or two. The thing that kills me is the fact that in most emergencies I've been involved in time was of the essence. Have you tried to untie one of these that has been on your wrist for a year? Dang hard.
I was one of the leaders who took a group of 600 youth this year to Wyoming in early June for a 4 day campout/Pioneering activity. We had storms roll through every night with 60+ mph winds and driving rains that shredded tents left and right. All my gear survived just fine because I set it up properly, but a lot of the other leaders had borrowed Walmart quality tents and didn't tie things down right. I had brought an extra 100' of paracord just in case and used it all with in the first 30 minutes of the first nights storm. I tossed my cord braclet to my wife and had her untie it. The Storm was done by the time she had it untied. I still used it but could have saved two more tents during the storm if it could have been untied quicker. By the end of the second night we had lost 1/3rd of the tents in camp and on the 3rd night we evacuated 300 kids to a big barn because the busses wouldn't make the 45 minute drive from town to our site because it had started snowing. Don't even get me started.
