I am toothpick! There have been many other inventions that have tried to replace me...dental floss, toothbrush, just to name a couple. But when you get right down to it, nothing is more convenient than me.
I've been around a very long time, even dating back to the days of the caveman. They got very angry when the animals they violently killed got stuck in their teeth. They weren't the smartest folks around, so they improvised with stone.....
But in 1872, a machine was invented that would make me and distrubute me to all with food stuck in their teeth!
