For my ID tags, I used a piece of hollowed out paracord over the metal bead necklace. I made sure the connector and maybe one inch of necklace were exposed, so that in the event of a snag, the necklace could break. I did this as I had a reaction to the metal, it turned my neck black.

At times, I also had a small knife, a small bic lighter and a small flashlight on the chain - just in case. Oh, the tags themselves were in plastic cases so as to deaden any noise.
