This Faber Castell 9000 sharpener has two sharpening holes and is suitable for colored pencils and graphite pencils. It has a compartment which will catch the shavings from wood-clad pencils. When not in use, the sharpening apparatus will slide down into a plastic case so that graphite dust cannot fall out of the sharpening holes.
Because the leads of graphite pencils are hard and resistant to breakages, they can take a very fine point. For pencils such as these, the Castell 9000 has a fine point sharpener, which will sharpen pencils to a 21 degree point. For colored pencils, which have softer leads, this product also has a shorter point sharpener. This will sharpen pencils to a 24 degree point.
This product should be replaced from time to time, as use will mean that the blade will blunten over time.
