KUM has been making pencil sharpeners in Erlangen, Germany since 1919 — the world's oldest pencil sharpener brand still in production, with almost every component made in-house to precise German tolerances.

What sets them apart is the curved dynamic blade: unlike flat blades that tear wood and snap leads, the curved profile maintains constant tension against the pencil during sharpening, keeping both casing and graphite intact. At Unfade we stock KUM sharpeners and erasers across a range of formats — from compact everyday sharpeners to specialist long-point artist versions.
