The Kuru Toga, 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. There are several model within Kurutoga

• Standard model : this is the basic type
• Roulette model : has a rubber grip , which is ergonomic and easy to handle

The Orenz mechanical pencil features 0.2 mm lead for amazingly thin, clean lines. It's great for writing notes, math problems, graphs, and more!
Despite being so fine, the lead doesn't break as you write, due to the innovative Orenz mechanism. The guide pipe protects the entire length of the lead, and you write without extending the lead out of the guide pipe, which glides right along the surface of the paper. Since it has rounded edges, the guide pipe doesn't catch on the paper or scratch it. As you write, the guide pipe gets shorter. When you need more lead, just click the top button as you would with any other mechanical pencil. The guide pipe will extend again, along with the lead inside.
Because there's no lead breakage, your papers remain clean without smudges from broken lead dust. You can also retract the guide pipe so it doesn't poke you or your belongings when you've stowed the pencil away.
