In addition to the compact dimensions of this sharpener that is suitable to be fitted into the BBox®, this sharpener stands out for two exclusive patents and a range of features that guarantee absolute quality:
• Blades MADE IN GERMANY.
• DYNAMIC TORSION ACTION® – Thanks to this patent, the blade dynamically adapts to the different forces applied to the pencil while it is tempered. These forces depend on the difference in material between wood and internal mine. The dynamic action of the blade is mainly based on its shape, slightly curved. If it was straight, like most of the existing sharpeners, there would not be a such high-level cut of mines.
• It is equipped with a related stick so that the blades can be easily cleaned with no damage.
• It is equipped with a custom-made chips holder.
