Self-Sharpening Pencil

Okay, I'd really like one of these!

Finally a Self-Sharpening Pencil

The Kuru Toga works by continually rotating a piece of "nano diamond lead" thanks to a rotating gear system inside the pencil. The rotation and sharpening ensures that the piece of lead will remain at a point giving you the same precise pencil marks you would get from a newly sharpened pencil.

I don't use pencils that often, but I prefer mechanical pencils because they do stay sharper than regular pencils--but even they only stay nice so long. It looks like this pencil has solved that issue. I wonder where I can buy one (and if it is affordable)!

PS I found one on Amazon, it doesn't seem too unreasonable for such a cool product...
