I work on cars quite a bit. This will come in handy for that and some home projects. I have a smaller Craftsman set (a metric & standard one) that I've had for quite a while that has come in handy whenever I needed it. I needed a good set for some larger nuts and bolts that I may encounter on the vehicles. This set is perfect for that. It's a BEAUTIFUL set. Well made and great quality. I just need to find a tap & die set that covers nuts and bolts from 17mm to 30mm (and equivalent sizes in standard measurements). I am giving it 4 stars because a portion of the metal case was dented pretty badly. I had to use my bench vise and ballpeen hammer to straighten it out as much as I could. It shouldn't have happened. Oh well... Still a great set...
