First Geeky Gift: Mechanical Pencil
Member HAL 9000 also shared his memory of his first Propelling Pencil (which, to be honest, took me a while to realize it is the same as the Mechanical Pencil). Mechanical/Propelling pencils are common stock these days, ranging in price from a few cents up to $13 or more. I hope the pencil featured here is a reasonable facsimile of the type of pencil HAL 9000 refers to in his discussion post.
