The Kuru Toga Mechanical Pencil by Uni
The Kuru Toga Mechanical Pencil by Uni. Each time you press and lift the pencil from the paper, the lead is slightly rotated by 9 degrees. With 40 presses, the lead makes a full 360 circle. In this video, we mark a white dot on the black section, and you can see the dot making a full circle back.
Kuru Toga came out in 2008 and for the past 10 years, Uni has made many different versions such as metallic grip, sliding sleeve and soft grip. In 2017, Uni even came out with a new version that rotates twice as fast — only 20 presses to make the full circle!
By gradually rotating the lead, the mechanism keeps the lead in your pencil sharp and maintains a consistent lead point. It prevents a slanted edge from forming and inconsistent thicknesses in your writing. A transparent window in the grip section of the pencil allows you to track the Kuru Toga logo, a circular loop, and see it moving around the circumference of the pencil as you write
Since the mechanism is triggered by vertical movement. If pen pressure is too weak, it does not rotate, but normal writing works perfectly 😊
