Contest: What is on your keychain?

I love to see things reduced to their smallest possible form while still maintaining function.

Show us the most interesting thing you have that fits on a keychain and have a chance to win a year of Instructables pro membership. It could be something you made or something you bought. To enter, post below a photo of the object or tool and give a link where it can be obtained or a brief description of how it was made.

Bonus points if it's something you find useful enough to actually carry with you everyday.

A circular spark plug gapping tool that lets me set automotive and marine plugs by just turning the disc between the point and the arm of the contact set on the plug.

Can you tell us where you got the mini multi-tool?
It is a Quarrow brand that is sold by the Bass Pro Shops. I think that Orvis may also sell them. Its called the "Turtle".

I don't have a wide variety of things on my keychain, I do have a lot of a few things.....the keys to my house are a bit old as you can see, and then there are the 20+ customer tracking tabs, and one brass George Killian's Irish Red bottle opener.
Nothing overly interesting, except the one skeliton key (upper left hand side).

Pandora's Box and inside of it is one of Chuck Noriss's beard hairs. Does that win anything?
