Normally, when you use a mechanical pencil, the lead wears down on the writing side first, so the lead gets progressively scratchier and sharper as
The Kurutoga has a Core Rotation Mechanism that continually rotates the pencil lead as you write. A spring-loaded clutch twists the lead incrementally every time you lift the pencil from the paper. This allows a uniform wearing of the lead so that it always remains pointed. This is great for students! It gives you an amazingly thin line. In effect, you use only 50% of the lead Area that you were previously using with your old mechanical pencil.
