Artist Sharpener, it's a special sharpener used for sharpening graphite pencils, charcoal pencils & pastel pencils.
The benefits are that when we sharpen our pencil with a knife we can expose more of the inner core of the pencil (without the wood encasing getting in the way.) If we cut the wood back a lot further than the tip of the pencil, we can lay the pencil flatter to the surface of the paper.
- Pencils have not contained lead for a long time, the cores are made of graphite powder that is bound into a solid form. Pencils break because they are brittle. If they are sharpened too much the tips get too thin and can be broken very easily.
Do you find this helpful? If when you sharpen a pencil of any kind and the shavings come off in little flakes, that means your sharpener blade is dull. If it is a good quality sharpener, you can buy replacement blades for it, if not, toss it out and buy a good one.
