A classic pencil sharpener by Caran d'Ache. This famous Swiss pencil sharpening machine, invented in 1933, reflects a commitment to exceptional quality. Form and function are combined with innovative design to produce a beautiful and time-honored pencil sharpener. It can be mounted to a desk, table or bookcase and has the ability to put a point on a round, hexagonal or triangular pencil and pastel. By pinching the butterfly clamps, the holding mechanism glides out to accept a pencil, and the pencil is held firmly in place for sharpening once the clamps are released.
