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 allows you to first cut the wood of a pencil, then shape the pencil lead. This results in longer, sharper, and finer pencil points. It undertakes the challenging task of cutting through both wood and graphite beautifully. The rust resistant blade can last through sharpening thousands of pencils, but may be replaced if necessary when used constantly with pencils 3H and harder.
