IDK what the deal is with them, but they're popular. Some people like having 20+ feet of 550 cord with them at all times because they like being prepared, or they just like bracelets, or both. I got into making them because I liked them, I had a few thousand feet of paracord just laying around, and the pure and simple fact that everyone else on the market ONLY makes the cobra and king cobra variants. I can make more patters of bracelets than most peple can even conceive of, but I have to limit what I sell because you don't want to overload people's minds. lol. IDK why everyone only makes the 2 most simple styles, espcially when there are so many more options out there. As far as slings go, I can even make single point tactical slings, normal length rifle and shotgun slings, and yes, even pistol lanyards. I can do just about anything you can imagine as far as carry systems, even belts. I can also put movable shoulder pads on the rifle slings, an make the slings either a specified length or make them adjustable. Yes, I have a lot of spare time. ;D
