The real wisdom in creating a multi tool is to make one that does what you need to do but doesn't have any extras. Added functions tend to make multi tools more bulky which decreases their utility. I remember once realizing there was no way to install a water bottle cage with the folding multi tool I was using because, no matter how I oriented the tool, it hit some part of the water bottle cage.
A job that would have been a cinch with a simple 4mm Allen key was impossible with that folding Allen key set.
I might be interested in a on-the-bike tool that had a set of tire levers, 4,5,6 Allen keys and a tiny needle nose pliers for extracting those tiny steel wires that keep puncturing my tires.
