All KUM sharpeners are equipped with blades manufactured with ultra-hard (65 hrc) and razor-sharp high carbon steel- harder than ball bearings, making them ideal for sharpening high-quality graphite.
KUM blades are slightly curved rather than dead straight- this means the edges are under constant tension and not lifted by pressure during sharpening. This provides a consistent sharpen to the pencil and prevents the pencil tip from springing out or tearing, and prevents the screws from loosening.

The perfect short cone pencil sharpener for highly porous and powdery leads. The Black Widow allows you to produce a round and pointed tip by simply removing and inserting the innovative TipFormer system. When in place, it sharpens a short round point. When removed it sharpens to a short sharp point. It also assists in keeping the cutting blade clean.
