Let's talk tools! What do you have? What couldn't you live without?

Someone "beat" me to a BFH.
But seriously it unbelievable how usefull my American made Dewalt 4 1/2 inch grinder is. Used with a cut off wheel. I went to buy a second one for convienance so I would not have to chance to a wire wheel. NONE were made in USA. So I scrapped the idea.
Also must have a wire feed.

Hand tools?
Ratcheting combo wrenches on the cars.
And at my work my Snap On ratching screw driver.
