I went to the neighborhood "hardware" store, and purchased small-diameter aircraft cable and ferrules to match. I checked at Home Depot, and while they have the aircraft cable, they don't have the ferrules, so the small Mom-and-Pop stores are probably the way to go. You need to have a cable cutting tool to get through the steel cable -- ordinary pliers or wire cutters just won't do the trick.
Here's what the finished product looks like: Duty days
I really like this idea, Where did you get the tag with the geocaching info on it?
