The Ingenious Design of the Screwdriver Handle

The most mundane things can have a way more interesting history than you know. Consider the lowly screwdriver. They come in all shapes and sizes, but the one you grab the most has a handle that comfortable and just plain works. And that's no accident. Its design has more features than you've ever considered, and its development goes back over a hundred years. Every part of it has a purpose. Along the way, fancier ideas have been proposed as improvements, but they've never really been able to beat the shape you've come to know.
