From Kate Freeman … Multitasking Smartphone Case Has 7 Tools in its Small Frame:
The ReadyCase is being touted as a MacGyver-like gadget. It does more than simply protect your phone from dings and scratches. The ReadyCase has a headphone clip so wires don't get tangled, a USB thumb drive (which is also a kickstand), plus two knives and a screwdriver.
All in all, the case has seven tools and it's only three millimeters thick.
