In the front two exterior pockets, the sewing kit fits in on the left and the Knipex fits in the right.
It's basically a mini commonly used hardware and medication pouch. I use fishing line for sewing in situations where I need strong thread, and I have various size needles in there too. The Altoids Smalls tin has a few of my most commonly used medication for me and my family. The Rolaids are for my heartburn unfortunately.
I use mine for bending sheet metal and holding objects while I saw them/work with them. I like to build things in my spare time, so I use them frequently for gripping, crunching, crimping, or wrenching sometimes.
