Well, fwiw, the best screwdriver I ever bought is a Vessel Megadora #900 +2x100 JIS screwdriver. They fit and grip derailleur adjustment screws like a boss. Not something you want to carry though long term. I tend to take the individual tools I may need as they are certain to fit well into whatever the application. Multi/many tools in one in my experience are inevitably inconsistent in mating well with what they are supposed to. Park and Pedro's come to mind. Husky folding hex sets have good precision if you need that many in one tool.
