Actually, I seem to categorize my tools into 3 main groups; mechanicing, wood working, and construction. There is some overlap, but not a lot.

The most use: screwdriver
Most time saving: 4.5" grinder with metal cutting wheel
Most indespensible: Timing light or air compressor
Requiring most skill: chizel
Most versatile: adjustable wrench

By the way, I was at a contractor's dinner the other night and won a brand spankin new 76 piece Craftsman Tool set (I was soo happy - more tools). Since this came in one of those premolded plastic cases, I'll keep this in one of the vehicles as a road box.
