This classic vacuum-operated hand-cranked pencil sharpener from Boston, USA, is a staple of classrooms in Europe and America from the last century. Its heavy-duty cast iron body, combined with a rubber suction cup base, securely attaches to a desk. It features an automatic pencil feed mechanism; simply turn the crank to sharpen your pencil. The device shows signs of normal, original use, with the mechanical gears and blade assembly in good condition. Its strong vintage industrial feel makes it both aesthetically pleasing and practical.
