I mean...just why?! I happen to have a swiss-army knife, a fairly cheap one. It has a small blade, a nail file, a pair of scissors, tweezers and a toothpick (and at the moment, a fair amount of sand in the wrong places). It is a rather slim and handy thing to have on a keyring, although I wish it had some extra stuff like a bottle opener and a saw.
But, this:

This is just wrong, in so many ways.
And it's £500 as well, even if it's got everything you could wish for on it.
Including:
- Mineral crystal magnifier with precision screwdriver
- Shortix laboratory key
- Special self-centering screwdriver for gunsights
- Tire tread gauge
- Golf divot repair tool
- Cupped cigar cutter with double-honed edges
And so much more...
