Vat19, self-proclaimed "purveyors of curiously awesome products," has released a pen that has dispensed with ink and writes with a metal alloy tip, boasting that it lasts a lifetime. As one writes with the pen, it leaves behind a trail of tiny metal "deposits," which look similar to a pencil in color, but cannot be erased, cannot be smudged, can write upside-down and can even write underwater. The pen never goes dull, though if one desires a sharper tip, they can simply refine the point with sandpaper.
