Ticonderoga Meets Kuru Toga

I just learned of the Ticonderoga Sensematic Auto-Feed Mechanical Pencil. "No clicking, no twisting, no sharpening! The Ticonderoga Sensematic is the world's only auto-feed mechanical pencil. Simply touch the pencil to paper and the Sensematic "senses" how much lead you need, advancing just the right amount as you write. You'll never again have to stop writing or drawing in order to sharpen your pencil." So goes the hype on the on-line store I found it at. Just imagine the kind of pencil that we could have if they combined the "auto-feed mechanism" of the Ticonderoga Sensematic with the "auto-rotating pencil" mechanism of the Kuru Toga! We'd have a pencil that always feed out lead automatically and would always stay sharp. Who knows, maybe one day it will happen.
