The Derwent Pastel pencil sharpeners are the easy way to achieve the perfect point. The pastel sharpener is specifically designed for use with the more fragile media of pastel pencils. It is also suitable for sharpening charcoal pencils and our other large diameter pencils, including Drawing and Artists.
Seems to sharpen without breaking pastel. Hilary Nettleton (Northwich, United Kingdom) on 15 May 2012
This sharpener has a cut out in the bottom of the cone section to allow the broken bits of chalk to drop out . It needs it as otherwise the bits would jam and have to be cleared with a knife. Unfortunately it it still manages to break some chalk pencils . I suspect the blade should have been placed at about 45 degrees to the axis but I don't know. Pastel pencils are fragile and probably always will be. Ernest Barton (London, United Kingdom) on 9 May 2019
This is OK and it does sharpen your pastels - but blunts quite quickly Susanne Biddle (Charente, France) on 14 May 2014
