"kneaded eraser" 的定义和意义

What is a "kneaded eraser"?

A kneaded eraser is a flexible, shapeable type of eraser used primarily in drawing and sketching. Made from a rubbery material, it can be shaped into different forms to accurately remove graphite or charcoal without damaging the paper. It is particularly useful for brightening areas or creating texture and can be repeatedly reshaped to stay effective. Unlike traditional erasers, a kneaded eraser can be shaped to fit into tight areas or to gently lighten areas without leaving any crumbs behind.
