Nitram Sharpening Bloc

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.
