The Originators of the

HB Degree System

Hardtmuth® Graphite is a premium lead that has been used in our professional artist’s pencils since 1802. Franz Hardtmuth, inventor of the graphite degree system, chose H after the family name Hardtmuth, B for the town Budějovice where our pencils are made, and F after himself. This varied degree drawing instrument has received accolaids from the world fairs in New York, Paris, London, Vienna, and Milan, and from Queen Victoria, who bestowed the name Koh-I-Noor on the pencils after the world reknown diamond as a representation of their finest quality.

Range 1 Degree: HB
Shape: Hexagon

The oversized 9mm lead core is perfectly centered in the California Cedar casing to ensure clean, even sharpening. The HB Hardtmuth cores are glued throughout the casing to eliminate breakage that results in the lead falling out after sharpening. These pencils have a smooth, silky laydown and provide coverage for larger works.
