Utili-Key

Several nerdy friends of mine who feel naked without their pocket knife have independently discovered that this handy mini-knife disguised as a key will both work in a pinch and -- shhhhhh! --pass through airport security checks unnoticed. Here is a way to travel with a knife at the ready. Just hand them your keys when you go through the machine!
I've had one, and when I bring my keys I have no trouble getting through security on international and domestic flights. I was surprised to find the other little gizmos incorporated into this miniature thing -- particularly the Philips screwdriver -- are just as useful.
Comments
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
