An enclosure forms the structure of a cosmetic pencil sharpener, featuring an entry point for pencil insertion and a sharpening mechanism that interacts with this entry. This sharpening mechanism consists of a pair of opposing planar cutting blades, each possessing straight cutting edges directed away from the entry. When put into action, these cutting blades separate upon pencil insertion, and they are designed to come together with a bias. This results in the cutting edges engaging the pencil's tip from opposite directions as the pencil is withdrawn.
