A crisp, sharp point makes a world of difference whether you are working on a technical drawing, writing a letter or creating a work of fine art. This sharpener is specially designed for left-handed artists. Featuring a snap-cap and a transparent receptacle that ensures mess-free sharpening, it also has a compact square shape that comfortably fits in the hand. The double-hole wedge is ideal for all pencils including large diameter art pencils; while the smaller 7.8mm hole is for standard pencil diameter and point-taper, the larger 11mm hole works well for careful sharpening of charcoal, pastels and colored pencils.
