Auto Feed Mechanical Pencils

Mechanical pencils that can feed the lead for you, avoiding all that clicky-clicky. In practice, these can be really useful when you're trying to take notes quickly, which is something pencils can be very good for.

The way these usually work needs you to leave the click-button alone - the lead will wear down until it meets the lead tube, and only feeds automatically as you continue writing, with the tube touching the paper. It's ok, the tube is perfectly polished, so it shouldn't catch on the paper at all, and helps protect the lead, so they can be a bit better at not snapping the lead if you're a bit too heavy-handed - it happens when you're trying to scribble things down fast!
