COMPACT FOLDABLE Bottle Opener (designed in Switzerland)

If you want a compact impressive bottle openenr or have a girlfriend who does not want to ruin their new nails, then you will have to print this thing!!!
Some time ago I saw this Smart One Handed Bottle Opener by Kart5a (http://www.thingiverse.com/thing:269463), but I hate to have something edgy, relatively big and bulky in my pocket (nothing against the other design!). So I thought there can be done something. This is the result! A compact bottle opener which fits nicely into your pocket.
This is still in development and I hope you can give me suggestions to make it better.
