The quality of a sharpener, especially its blade, is crucial for achieving precise lead sharpening. Graphite leads, being more robust and hard, can be sharpened to a very fine point. To maintain ideal sharpness and reduce frequent lead breakage, periodic replacement is recommended, as the blade loses effectiveness with use over time. This lead sharpener is the ideal complement to all mechanical pencils, sharpening fine leads with diameters of 2 and 3.15 mm and includes a reservoir, ensuring practicality and durability in daily use.
