That is a drag that the link didn't work.
I --want-- one of the brass keychain wrenches! I have seen a lot keychain wrenches and they are usually always dreck.
But with solid brass you could get out the files and scrapers and what not, carve it some, and make a tool out of it!
The necklace couldn't look elegant no matter what you did. To my eye anyway. There is already too little metal to work with if you wanted shapely tools.
You could always repaint the box Brian. heeheheheheheeh
If I see one cheap though, I'll remember.
