Any of the suggestions here would work well especially with Leatherman making such excellent screwdrivers and bits .But for my needs (BOMB PROOF AND SIMPLE TO USE )I can't beat the Victorinox Swisstool the screwdriver bits can be a touch awkward much like the standard s.a.k but the rest of the tools work really well and if it gets gummed up you can even throw it in the dishwasher with the makers blessing! <img src="/ubbthreads/images/graemlins/ooo.gif" alt="" />
