Updated 1.25.12 I do, So I did this. Two 1/8" chain links Pin goes through the hole in the keys Fits 3 keys This was a small experiment to see if it would successfully work, and so far its been about 3 weeks and not a problem although I may use a nicer looking chain (TiN or just black) UPDATE 12-6 I decided to kill the split ring and just carry the keys on the link with a simple paracord lanyard. Zero Issues in the three months or so that I've been using it. UPDATE 9-25 I was playing around when I woke up earlier than I expected and had a few hours to kill. Along with cleaning, and loading up my new maxped bag, I came up with this. Took a bicycle master link 1/8th inch and used it as a shackle. Cosists of three pieces the link a spacer and a clip. Easily taken apart with multitool pliers, a screw driver (flathead =D) or if all else fails a coin works fine. UPDATE 1-25 I put it back on the biner to see how it would work... Perfect. I need to get a black or brass masterlink from a KMC 710sl chain as well as a nicer biner and Ill be set!
