The tip of the screwdriver is pretty sharp. If you attach the unit to a keychain, you wear open in your pocket, you can stroll down the duration bag broken. So it is good only for Keyes.
And the bottle is the other bad design. Enough leverage you only when it is fully opened. Here then is the page on which you have to apply pressure, but the ausgrechnet with the saw and the knife blade. One can then hold them in other locations, which then ensures that it is very easy to collapse. As a bottle is pretty useless. Although I get open a bottle of it, but that was an unpleasant and painful fiddling.
Generally one can say that it's bigger than it looks in the photos. It's a bit longer than a standard house key. The workmanship is top quality, the packaging is also nice. The locking is very robust and you have to have no fear that it dissolves by itself from keychain.
The knife is good for the tiny size (2cm) rather as a letter opener that similar long saw is maybe have a purpose, but I can think of none.
On the one hand a somehow cool and pretty gimmick, but practical applications, it is primarily through the concept called weaknesses probably not so many. Better to be a very small Swiss Army knife or Leatherman Micra occupy. Although the slightly larger, but still small enough for your key ring and you can really do something with it.
