Just because there is an app for everything nowadays doesn't mean that you shouldn't own at least one of these miniscule multi-tools. Multi-tools are great no matter what size they are, but it is when they can fit into the palm of your hand or your pocket that they truly attain the title of "awesome."
You might not think a screwdriver or Swiss Army Knife is awesome, but just wait until you need to cut something a la "127 Hours" or screw something in nearly every mundane home repair task. You can't truly call yourself handy until you own at least one of these miniscule multi-tools, so check them all out today. I have said it before and I will say it again, the guy with the screwdriver-bottle opener combo has been and always will be the coolest guy at the party.
