Like others here, I'm a tech for VW. I have a good assortment of tools at work, but nothing at home! I'm forced to use whatever tools I can find at home and improvise a lot. Basic tools are a flathead screwdriver and a 10mm deep socket. Otherwise, I couldn't live without my dremels and their bits, pliers, and a vice. Oh yeah, of course a good solid workbench.
Of course the bike never breaks at work, only at home or on the road
