Sharpener Made in Germany

KUM stands for Made in Germany. At our location in Erlangen, we have our own production, a development department and a department for tool and mechanical engineering. Everything from a single source!

Investment in the future

Through our production in Germany, we secure jobs and promote regional value creation. We invest in training young professionals to pass on knowledge and skills.

These investments in training and the continuous development of our employees help us to grow and innovate as a company.

“Made in Germany” not only means excellent sharpeners, but also stands for economic stability and social responsibility.

KUM Dynamic Torison Action

We are the only manufacturer in the world to equip our sharpeners with a curved blade. Due to the curved blade, the edges are under constant tension and are not lifted by the pressure when sharpened. Therefore, “rebounding” or “tearing” of the pen tip can be ruled out. Furthermore, the pressure against the screw prevents it from loosening or loosening.

KUM Blades

Probably the most important component is the blade. If a blade does not work cleanly and reliably, i.e. sharpens the pencil with high precision, then the entire sharpener is worthless.

Our blades are manufactured with a measuring tolerance of 5/100 mm. Equally important is the hardening of these blades. We harden the steel with 64 HRC. For comparison and understanding: Top blades for use in the kitchen have a maximum of 53 HRC. These sub-processes are the most complicated in the production of the product. This hardness is necessary because pencil leads contain clay, which is a type of rock. Usually, metal is sanded down with stone, but the sharpener does it the other way around!

Carbon steel rusts relatively easily, so each KUM blade is protected by three careful operations:

  • Polish
  • Ultrasonic cleaning
  • Coating with oil
