The Stockmar double sharpener is made from a sturdy yet light magnesium alloy. With two openings, it sharpens both thick and thin pencils: round, hexagonal (like the rainbow pencil) and triangular.

The sharpener sits comfortably in the hand, for young and old alike, and the blade is replaceable. Suitable for graphite, coloured and watercolour pencils, and a lovely addition to the thick Stockmar pencils.
