Thanks again folks - some great advice here.
I'm not an experienced bike mechanic - a rookie in fact. I think I just need a decent quality item with the most common tools - hex keys, Torx and Phillips screwdriver.
Here is a possible example of "making sure" concerning which tool bits you need to fit which bike bits. Few bikes need a Philips screwdriver ... or a Pozidrive. What many need is a JIS screwdriver, for the cross-headed items found on things like Shimano derailleur components. JIS is "Japanese Industrial Standard" by the way. JIS looks like a Philips or Pozidrive but it's different in shape.
It's all too easy, if adjusting your derailleur throw or similar, out on the road, to mangle the screw tip of a JIS screw with a Philips screwdriver. it'll cam-out and mangle, unless you're extremely careful and the screw isn't too tight in its threads. Once you've mangled the screw tip, accurate adjustments will be somewhat difficult, even if you subsequently find & use a JIS screwdriver.
