Joining such USB drives as the Aigo and the bottle opener USB drive, here’s another that’s actually useful for more then just holding data. The eraser flash drive. Because sometimes you gotta, you know, erase stuff.
Instructables will show you how to make one, if the one you have now is just too ugly or with a broken case. Then you’ll know the joy of being able to erase whenever your USB drive is near. Assuming you still use a pencil, that is.
