Back in the mid to late 90's a company called Swiss*Tech was making some very cool stuff- tools like this one, the Screwball.
I myself have had many times where I have not only needed a screwdriver but one to loosen or tighten a torx head or a square head.
What kind of people would write collect and review multitools? Quite simple really- we are designers and do-ers, outdoors types and indoor types, mechanics, doctors, problem solvers and problem makers. As such, we have, as a world spanning community, put every type, size and version of multitool, multifunction knife, pocket knife and all related products to every test we could manage in as many places and environments as there are.
