|Blending stumps are very useful|
for shading and adding value in graphite drawings.
A clean stump can also lift off graphite
in small bits from a drawing as well.
|The tips tend to wear down quickly|
with over use
but can brought back to
a point by
rubbing them on an emery board.
|I especially like using these when making Zentangles.|
