Full Pockets

I carry too much. I mean literally. I even carry what I call a man purse that's really just a backpack full of stuff. On the other hand the only thing that I want to carry in my pocket is my phone and my Leatherman WAVE

 

My pockets are starting to all have a worn out pattern of my Leatherman because of how much I use it. This multitool is a version that is a few generations from the original design and it has so many minor improvements that make it a perfect all around tool. They say that a bird in the hand is better than 2 in the bush. Well this tool that is in my pocket when I need it is way better than a toolbox just out of reach.
