Pininfarina is known for turning Ferraris and other exotic cars into even more impressive works of art, so it's a safe assumption that its new 4.EVER Pininfarina Cambiano writing instrument is going to cost a small fortune when available. But with an inkless design that never needs a new cartridge, it could eventually pay for itself -- after a century of use.
Where you'd normally find a ballpoint tip, on the Cambiano there's what's called an ethergraph tip which is a special metal alloy that leaves behind a trail on paper not unlike a graphite pencil. Except that this writing instrument never needs sharpening. It will supposedly write forever, or at the least will keep on going until you're done paying it off. [Pininfarina via Uncrate]
