Möbius + Ruppert is a pioneer in the manufacturing of pencil sharpeners. In 1908, Theodor Paul Möbius invented the first pencil sharpener to be produced industrially. The family business continued its production of sharp pencil sharpeners, and in 1922, brother Alfred Möbius joined forces with Heinrich Ruppert to establish the company Möbius + Ruppert. Today, the company designs pencil sharpeners and high-quality drawing equipment for offices, schools, and hobbies. @@aipolicy
