The Pencil X-Ray Teardown

In a world of Apple Pencils and styluses, sometimes we forget the the old writing instruments that have almost been completely replaced by finger swipes and keyboards. Although I consider myself a geek at heart, I still carry around an old style paper notebook to write ideas and to do lists. Nothing better to share your ideas with than a clean sheet of paper. And the mechanical pencil is your best friend there! So today we will look in detail on how this nice mechanical pencil is built, starting with a couple of animations showing the action of pushing the lead out.
