A carbon fiber pencil with a reverse clamp system that allows a simple and intuitive placement of the mine

Carbonara is a pencil where carbon fiber has a mechanical purpose beyond aesthetics, provided with an innovative system of quick, simple and intuitive placement of the mine. Carbonara dispenses with complex parts and mechanisms, works by flexing the carbon fiber.

BoO Barcelona have always wanted to design with carbon fiber, but they didn’t just want visual elements without a real use. For this reason, they have been working the technical characteristics of carbon fiber for more than a year, to develop a 2 mm lead holder which can only be produced in carbon fiber: Carbonara pencil.

The design of the Carbonara pencil comes from the concept of reverse clamp, by pressing on the carbon cylindrical body, the aluminum tip it separates enough to position the mine, in rest mode the lead remains firmly fixed in the part striated from the tip.

The Carbonara pencil doesn’t have any mechanisms and it works through bending of the carbon fiber 3K sarga with a bidirectional fiber orientation and aluminum 5000 serie. This set acts as a pen. When users press the carbon fiber it opens and the lead slides out and when they stop pressing, it closes.

The Carbonara pencil has a quick lead release. Users only have to press the carbon fiber to release the aluminum tip and the lead will slide in and out. The hole that permits the bending of the carbon fiber can also be used as a lead window, to see the color of the lead, the hardness of it.

The main feature of the Carbonara pencil, and what makes it possible to develop the innovative grip and grading system of the mine, is the use of carbon fiber as a distinctive material. The lightness and the mechanical properties of the material plus the design of the set, achieves a surprising result, resistant but flexible, light and durable, also with a refined aesthetic.

The Carbonara pencil weighs 7.3 grams (0.26 oz) and comes in two finishes: Glossy Silver and Matte Black. The difference lies not only in the color of the tips and the aluminum cap, but also in the carbon body, which can be matt or glossy.
