Kum, a leader in the science of pencil sharpening, has a line of pencil sharpeners that target minute details of the pencil sharpening process. Each sharpener features an ultra-hard high-carbon steel blade held securely in place by a screw (versus a rivet which can cause the blade to wobble). The razor sharp blade fits inside a cone-shaped hole that has narrow grooves to reduce friction, allowing you to turn and sharpen pencils with less effort.
This particular sharpener gives you two options for your pencil, one that produces a long and sharp point (for harder lead grades) and one that produces a shorter point (for softer lead grades). Lightweight body is decorated with fun pencil illustrations.
