Faber-Castell Double sharpener

50-34 Metal Double Sharpener

The quality of the sharpener, especially the blade, is crucial for optimal sharpening of wooden-cased pencils. Graphite pencils can be sharpened to a particularly fine and thin point due to their robust and hard leads. Colored pencils, on the other hand, are sharpened shorter and blunter because of their softer leads. To ensure optimal sharpening, we recommend replacing the sharpener from time to time, as the sharpener blade becomes dull over time. This can lead to increased lead breakage.
