As a carpenter / tradesman I use this on a day to day basis, people not in trades won't care about this product though. I bought a socket that is supposed to grip all nuts and bolts from 7mm / 1/4" to like 19mm to 3/4", and it can put in hangars and such. It replaces so many tools in my toolbox and does a lot better job than the ones I had. I cannot stand to work without this tool, but I have yet to find any stores that sell it, I always have to order online.


Not sure what you want to call it, but here's a picture:
