In the early days, gadgeteers didn't have touchscreens and octa-core processors to play with.
In the very early days, they didn't even have electricity. But despite that, these gadgets from a time when technology went "clunk" have weathered the ages, and are still in widespread use even today. If it ain't broke, don't fix it. And if it is broke, fix it with a wrench.
Victorinox Swiss Army Knife (1891)

Face it, you’re going to look a bit silly turning up to a Cruise missile fight brandishing a nail file. Still, no Scout worth his woggle has ever been caught without a Swiss Army Knife to hand.
