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 accolades 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-renowned diamond as a representation of their finest quality.
Range 20 Degrees: 10H - 8B
Toison D’or pencils are the pinnacle of graphite drawing instruments. Encased in California cedar, they can be identified by their black laquer and cream, gold, and black bands. California cedar is one of the best woods for pencil making because it is a renewable resource that prevents warpage. The Hardtmuth leads are perfectly centered within the casing to ensure even, clean sharpening, and are glued throughout to prevent breakage. Premium Hardtmuth® graphite is combined with a select mixture of clays and high quality, proprietary binders to create an extra smooth drawing lead that doesn’t scratch or snag, regardless of degree.
