What is the best tool set?

[Beadle]

I'll second that. The most used tool on my boat is a vice which clamps on the companionway steps. The second most used is a hacksaw.
Of course I have lots of other tools on board but I would not like to go to sea without a complete set of ring/open jaw spanners, socket set, screw drivers, "stanley" type knife and a cordless drill fully charged + set of drills.

You forgot the hammer, and for that matter, the chisel to go with it.

You forgot the hammer, and for that matter, the chisel to go with it.

I friend has a tale of breaking down on his (Italian) bike in the Alps. A German rider stopped to help, on an old, but well-kept BMW. Mate says he just needs a hammer to persuade a shift rose-joint back into place. BMW-rider produces a comprehensive and immaculate tool-roll and asks "Would you like to borrow my small hammer or my large hammer?"

The good thing about hammers is that there is none of this imperial/UNC/UNF/metric/fine-pitch/Phillips/Pozidrive, etc. nonsense...
