Hmmm - you mean something like a gradient map?
Above a certain level it's paint, below a certain level it's wood, and then
put a bit of
turbulence in it, so there is a little paint in the wood area, and a little
wood in the paint area?

This would work for ROUND pencils, where the dividing line is a circle
contained in a plane, but what about the hex pencils? the dividing line is a
complex shape.

It also occurred to me that for the most part, your camera is not going to
be doing a zoom in on the sharpened point :) If it's a desk scene, pencils
might just be decor. Maybe it's more trouble than it's worth to fix this? I
don't know.

A CSG solution that I might tinker with, is subtracting a number of small
diameter, short cylinders, whose long axis is aligned with the side of the
shear_cone and randomly distributed around the perimeter of the pencil.
Alternatively, small, unevenly scaled spheres might work better. This would
approximate 'dings and dent' along that border. Again - the hex pencil is a
much tougher problem.
