The M+R Discos pencil sharpener is a precision instrument manufactured in Germany by Möbius + Ruppert. Constructed of solid brass with a nickel-plated finish, the device features a dual-aperture design: one aperture for standard pencils, a second for larger diameter pencils up to 11mm. Its engineering enables consistent point preparation, with particular efficacy for colored pencils and drawing tools.

Technical specifications include a replaceable sharpening blade, compact dimensions for portability, and a mechanical configuration that produces a long, acute point suitable for detailed graphic work. The sharpener's design prioritizes durability and precision, making it one of the best sharpeners we have ever used.
