Pencils with a hard core such as oil-based coloured pencils (Faber castell Polychromos) and the graphite H leads are strong enough to be sharpened to a longer point than a standard pencil sharpener.

X2 provides stretch, flammability and abrasion performance in an unobstrusive background grey mélange effect. You can choose a sharpener that catches the shavings, a desktop sharpener, an open sharpener, or an electric pencil sharpener.

The wider gauge hole is fitted with a removable steel blade which is perfectly positioned to be gentle on wider diameter, pastel cores. Some Artists prefer to use a craft knife to sharpen their pencils because it allows them full control of the shape and length of their pencil point. When working with graphite pencils, I will sharpen grades to varying lengths dependent on the size of an area I am trying to cover. As with coloured pencils, the graphite leads are defined as either hard or soft - the H stands for Hard and is far more robust at a long point and the B leads are softer, getting softer the higher the B number, so care must be taken when sharpening these to a long point as they are more likely to break if too much pressure is applied.The end result is an intriguing, two tone upholstery fabric with subtle surface interest, style and beautiful simplicity.

There are two reasons why a long point sharpener may be ideal for you, the first is it can create an extremely fine tip ideal for very thin lines, the second reason is the one I use in my own work and that is to create a longer nib that will cover a larger section of paper and minimise harsh edges to enable an easier blend of tones, particularly important for tonal backgrounds.Primarily as a coloured pencil artist myself, I use the Derwent battery powered sharpener simply for quickness and minimal mess. Using the length of the 'lead' avoids harsh lines which can be left on the paper if creating a tonal background with the tip of the pencil, which you may not be able to blend away. We source and negotiate pricing on a wide range of supplies on behalf of local Swindon Schools, effectively we become an extension of your organisation, with our key priorities being. This can cause a weakness in the pencil so I decided to wrap strong tape around the split which has never caused any issues over it's lifespan.
