The quality of a sharpener, especially the blade, is crucial for optimum sharpening of wood-clad pencils. Due to their robust and hard leads, graphite pencils can be sharpened to a very thin point.
- Softer and colour leads are sharpened to a shorter and blunter point
- For optimum sharpening, we recommend replacing the sharpener now and then to prevent tip breakages
