Sounds like we all carry about the same things I've got an old hand carry tool box with Imperial Wrenches, Sockets (1/4, 3/8, and 1/2 drive), assortment of pliers (side cutters, needlenose, slipjoint, and a few pairs of different sized and styled vice-grips), a few different hammers (Ball Peen, Sledge etc), flashlight, gloves (Mechanix type and regular work gloves), box opener style knife, tape (masking & duct tape), sharpie or anytype of permanent marker, also an assortment of screw drivers and a small pry bar.
Other tools I bring along depending on what I'm after; 24V cordless reciprocating saw, old floor jack, jack stands, and other misc items that really do depend on what I need to remove, big or small.
