One of the best simple pencil sharpeners for writing pencils. The blade holds its sharpness possibly even longer than the KUM ones, if not at the same level. It also has 2 extra blades at the bottom, while it comes in a plastic case to protect it and always have the blades together. The M=R is a well-known German company with good quality products. I would recommend it for middle/high school students or anyone who uses pencils only for writing and not for drawing or sketching.
