These tough plastic sharpeners have an attractive slim elliptic shape for easy storage in pockets or briefcases. The double-hole XL sharpener features an extra-large holding container and a swing blade shutter so that when the pencil is removed after sharpening the blade closes and no shavings leave the container. The smaller hole (7.8mm) is for standard pencil diameter and point-taper. The larger hole (11mm) is perfect for careful sharpening of charcoal, pastels and colored pencils. It also has a large capacity receptacle for shavings. The blade may be replaced with MG100-0050.
