Single most-essential tool for kit building?

[DigitalGriffin]

Hobby knife, spare blades, xuron rail nippers (can be used to cut parts from sprues and cut track), tweezers (self closing and regular closing)

if you are doing trackwork, soldering iron, voltmeter, T-pins, nail punch (I like to nail the ends of my track down)

Single most essential tool for kit building? That would be a bottle opener to crack a beer with.

I think out of the box. The most important tool is a brain that can read an instruction and come up with a way to carry it out as simply and/or effectively as possible
