That is a tool kit for an expedition cyclist.
You really need 3 kits: one is a basic puncture kit for journeys of about 3 miles or so, where you could walk back, but don't want too.
Another for longer commutes, training routes day tours etc which can fix most roadside mechanicals.
The expedition toolkit is one you can use for serious stripdown maintenance if your bike falls into a muddy ford or gets left out in a sandstorm.
