KUM 300-2 Brass DWedge Sharpener

All KUM sharpenersare 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.This stylish and sturdy solid brass sharpener is suitable for pencils up to 8mm in diameter in the small hole, and 11mm in the large hole.
