An extraordinary sharpener – hand-made in Germany.
The KUM Masterpiece passes through eight quality checks, during the production process nothing is left to chance. Special blades, tests after each single production step and a high-quality precision work guarantee the uniqueness of this sharpener.
A new dimension of long-cone (sharpeners)
The KUM® Masterpiece sharpens in two phases. In phase one only the wood of the pencil is removed. The removal of the shavings is set to a TC system, the so-called Thin Cut. In phase two, the lead is sensitively sharpened and formed.
The goal is to obtain a long and precise pen tip. The result is a conical shaping based on 8 degrees.
The prerequisite for this perfection is a centered lead and first-class wood. Second and third grade pens will fail here.
High quality material
The sharpener is made of magnesium, a high-tech material. Magnesium is not only lightweight, but also ensures the perfect fit of the blade. The blades are made of finely ground high-carbon steel. This steel – with a hardness of more than 62 hrc – is much harder than any high quality kitchen knife (about 55 hrc).
Due to the Dynamic Torsion Action®, the blades are under constant tension, preventing the tip of the pen from breaking out.
The sliding stopper permits to uncover the lead.
An uncovered lead gives the artist an additional freedom of design
