Serious upgrade from the standard key-ring that most people use on their key-chains. A key-chain is a core element of many people's EDC containing several key items (home key, car key, multi-tool, small Swiss army knife,and flash-lite, all on a large carabiner), however this usually changes depending on where you go and what you do on any given day. For example if I am called in for jury duty I will need to remove nearly all of these items for they are not permitted in a court house. With this lucky line you can easily take items on and off your key-chain without having to pry apart a cumbersome metal ring.
