This Faber-Castell Dual Sharpener for Artists is unique in its ability to work well with a multitude of artistic tools. Due to their robust and hard leads, graphite pencils can be sharpened to a very thin point. Because of their softer leads, colored pencils should be sharpened to a shorter and blunter point. This sharpener will accomplish both tasks. Features replaceable blades and an adjustable sharpness setting.
