If you use mechanical pencils a lot, you know that the wearing down of the lead on one side is a pain. No one ever uses the pencil straight up and down (as it was intended for drafting), so you get a line that is bigger than the true cross-section of the lead. The Kuru Toga from Uni-ball solves the lead wear problem by slightly rotating the lead when the pencil is brought to paper. This distributes the wear over the section, resulting in a consistent fine point. Pretty cool, and a smart solution to a very common problem.
