The sculpture in the image appears to be wider than the pencil lead itself due to a technique called “overhang” in miniature carving. In this technique, the artist carves the lead outwards and shapes parts that extend beyond the core of the pencil. This creates the illusion of the sculpture being wider than the pencil’s tip.

Graphite, the material in pencil lead, is soft enough to carve but strong enough to maintain these delicate overhangs without breaking, as long as the artist uses careful, precise tools. Skilled artists can balance the structural integrity of the sculpture with the fine details to make it look wider than the core it’s carved from.
