Could you please send me a key as well? My co-worker just asked where to get a cheap key, I’m sure that a free one will make her happy. :)

A Victorinox Manager. It contains a small blade, a bottle opener with a magnetic Phillips screwdriver, a pen, a nail file, scissors and tweezers, all in a very compact form factor.

10,000 mg equals 10 g, not 10 kg, so you would only need 1/100 of your body weight. Still an unrealistic amount, but far away from 10x.

I like Gallade.
