Do you like to be prepared? Then you’ll love this standard issue dog tag tool from Prometheus Design Werx. The titanium accessory is the exact same size as a standard American military issue dog tag, but it can do much, much more.
How much more, you ask? Well, there’s a 6mm bit driver carved into one side and a low-profile bottle opener in the other. One of the edges also functions as a screwdriver head, while the area carved out of the center will work as a closed end wrench for both metric and standard hardware.
