Re: The only tool you'll ever need...
I lived in Leicester, once. There, sledgehammers were often referred to as "Birmingham screwdrivers."
I associate percussive maintenance most often with early 1990s Seagate hard disks. But then, I am also ancient enough to remember 8" 160k floppy disks, hard sectors and the days when you could resurrect lost files on CP/M disks with a disk sector editor called du.com.
And sometimes a razorblade.
For real precision work.
Mind you don't slip.
Oh crap. Pass me another trainee, Dave? Ta.
