This is hands down, MY FAVORITE tool. When in question of bolt size, Grab this. When your have multiple sized bolts and nuts and don't want to walk back and forth to the box, grab this. Need to bend some metal in the middle of a job with out marring the surface, these will do. Don't want to spend money on a 2" socket, No problem. Need to do a press fit of two pieces that JUST BARELY are interference fit, you have these.
I received a pair of these when I started A&P school (Aircraft Maintenance), and over my 10 year carrier, at my home, and on my vehicles I grab this most often. It is the King of multi purpose tools and although it is not the best at anything, it is the fastest and easiest solution more times than not. If I was stranded on the side of the road, I would want these with me.
As a professional, I love these. As a home owner, I love these, As shade tree mechanic, I love these.
