I'm constantly searching for "the one best pocket tool" ... which of course doesn't exist. Requirements for me are that you're allowed to take it on a plane, it has a knife blade and some screwdrivers, scissors, bottle opener. At the same time they should not be the heaviest or most clunky part of my EDC equipment.
As I've been using Swiss Army Knives by Victorinox since my father gave me my first pocket knife when I was 8 I'm still a little attached to these tools. ;-)
Currently I use a Victorinox Cybertool 29 or a Victorinox Outrider which both only cover some aspects.
So what are your experiences and recommendations?
