Eraser for shading

Putty eraser is an indispensable tool for graphic artists working with "delicate" graphic materials: charcoal, sepia, sanguine, graphite, and others. It is made from a pliable material that is excellent for kneading by hand. The putty eraser differs from a... regular eraser in that while a regular eraser simply removes the thin top layer of paper, the putty eraser effectively captures particles of graphic material without damaging the paper and without smudging the drawing. If you shape the putty into a wedge, you can easily erase fine details of the drawing.
