I've always thought Swiss Army Knives needed a money clip integrated into its design. You already keep the thing in your pocket, so might as well find a way to have it hold your folded bills. While that hasn't really happened yet (honestly, I don't know how to work that in the design either), turns out someone saw the wisdom in the mash-up and made the Delk Money Clip Multi-Tool.
Instead of starting from a pocket knife design, they went the other route, piling on the extra tools on a traditional money clip. The result is a very capable pocket tool to hold all your loose bills, with a few extra utilities you can pull out when needed.
The Delk Money Clip Multi-Tool measures 2.25 x 1 inches (l x w), making it compact enough to fit even into tight pockets. Behind the actual clip for your loose bills are four fold-out multi-tools waiting to be deployed: a knife, a pair of small scissors, a file and a flathead screwdriver. Everything is constructed out of stainless steel.
Granted, this doesn't even begin to come near what most pocket knife multi-tools offer. Still, if you rarely use those tiny blades or screwdrivers anyway and merely keep them for emergencies, we're guessing something like this is going to do.
