All of them:)

That is so true. Every time I do a set or even one dog-leg, I'll stand up and look at the ground and wonder "where the hell did all these tools come from and how many did I really need"

Grinders, cutters, sanders, sheet metal, tin snips, hammers, files, screw drivers for scraping areas ya can't reach, fiberglass, bondo, mixing cups and plates, markers, rulers, extension cords, welder, etc, etc.
