 What is a Mechanical Pencil?
The first mechanical pencil was invented in Britain in the early 1820s, and patented by John Hawkins and Sampson Mordon in 1822.
Once the mechanical pencil is closed, lead can be pushed through the barrel in small increments -- as it is used -- by clicking the tip of the pen, depressing a ratchet button, or twisting the cone of the barrel, depending on the model.
The advantage of a mechanical pencil is that the lead is so thin that it's always sharp, allowing precise and uniform strokes without the hassle of constant sharpening.
