Cell phones were made to call people on the move... Which seems to be the thing they're less used for nowadays.
Crowbars were meant to dislodge crows' nests, thus "crow-bar", and not to bludgeon people and crates.
Shotguns were mostly designed for hunting animals of the "not-human" kind.
Hunting was originally for food, not sport or thrill.
Computers were created for work and not recreational purposes.
...etc. We have a way of subverting things from their original purpose into... whatever we feel like really, usually anything other than it's original purpose.
