The Blackwing Desktop Sharpener uses a helix blade to sharpen your pencils to perfection. The dial on the crank allows you to adjust the point from long and curved to short and blunt. Its unique sharpening system retracts the pencil automatically without scuffing the finish, and it includes an automatic brake to prevent over-sharpening.
