Nitram Sharpening Bloc

Product excellent for Nitram charcoal, particularly the hard sticks. Long lasting grit. Most other sharpening block/pads are far to quickly rendered smooth by hard charcoal. Very good size for long sharp points.

Works well for adding that finer point for charcoal sticks, willow charcoal., and charcoal pencils. Reasonable result with pastel pencils as well.

good quality, brings graphite to a fine point quickly, the size allows you to keep the dust on paddle without it flying everywhere

The Nitram Sharpening Bloc is so much easier to use than ordinary sandpaper as it is sturdy and the handle makes it portable to use at any angle. I have had good results sharpening the Mars Lumograph pencils into long points for drawing and shading. It's a good size and comes with an extra pad which is good too.
