Uni-ball Kuru Toga Auto Lead Rotation Mechanical Pencil - 0.5 mm - Green Body

1. As you start to write you might have a sharp point, but as you continue to write the point is worn down and thus your line widths are not uniform. This can also lead to smudgy and thick lines.

2. If you pick the pencil up and happen to start writing with the tip of the angled point, it is likely to scratch or catch on the paper.

3. The different angles at which the pencil lead comes in to contact with the paper is a common cause of lead breakage.

The Kuru Toga, on the other hand, has a core rotation mechanism that continually rotates the pencil lead as you write. The lead is twisted through a spring-loaded clutch, it works by twisting incrementally every time you lift the pencil up (i.e. during printing words, etc). This allows a uniform wearing of the pencil lead so that it always remains as a pointed tip. Not only does it solve the above problems, but it also gives you an amazingly thin line. You are effectively using only 50% of the lead area that you were previously using with your old mechanical pencil. Thus, a 0.3 mm Kuru Toga will write incredibly thin lines and have less breakage than a standard 0.3 mm mechanical pencil.
