You might not need to lug around a heavy emergency tool kit when you can own this Cole-Bar Hammer.

The hammer isn't what it seems. It's really 7 tools in 1. Apart from being a hammer, it's also a crowbar, ruler, demolition tool, socket wrench, angle measurement tool, and nail pliers.

For $79, it's available for pre-order here. Watch the Cole-Bar Hammer being demonstrated in the video below:
