D-ring accessories

[Shorttime]

I've got a big D-ring with my keys on it, and a DIY bit driver, thanks to Instructables.

Anybody got other ideas for things to hang there?

Widgy bar! I love mine. Maybe a nice, loud whistle if that sort of thing blows your skirt up. A daisy-chained hank of paracord is nice. It gives you something to grab your keys by, and you have the cord on hand if you need it (also turns your keys into a mini-flail while remaining inconspicuous.)
