You can buy a stock Swiss Army knife with a USB drive but they tend to be short on implements and mostly filled with a bulky full-size thumb drive. This hack adds a tiny USB drive to a normal knife for the best of both worlds.
How do you pull off the hybrid build? You’ll need to do a little grinding on the bottle opener to create room for your USB drive and then use a little epoxy to secure it into the slot you’ve created. Assuming you have an angle grinder (or some other suitable tool on hand) it’s a very straight forward little modification. Hit up the link below for more details.
