KUM Pencil Sharpeners-Plastic Body

Not all sharpeners are created equal! 
KUM Artists Sharpeners are without peer with regard to materials and manufacture. KUM sharpeners are equipped with blades manufactured with ultra-hard (65 hrc) and razor-sharp high carbon steel. The blades on a KUM sharpener are harder than ball bearings or any high-quality knife, providing you with the ideal instrument to sharpen the hard, quality graphite found in Artists pencils.
KUM blades are slightly curved rather than dead straight. The curved blade 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. Additionally, the pressure against the screws prevent them from loosening. 
Plastic Bodied Sharpeners – The plastic body is precision injection molded to ensure long lasting stability and toughness. The injection mold is so accurate that it allows for shrinkage of the plastic when it is ejected from the mold and cools.
