The chalk sharpener is the perfect tool for sharpening dressmaker’s and magic chalk from Prym. On the upper side of the violet plastic chalk sharpener there are V-shaped plastic edges,on which the worn chalk slab is moved to and fro until it becomes sharp once more. As the chalk is sharpened, the dust from the chalk falls into the chalk sharpener's integral container. A slide on the underside allows the chalk sharpener to be opened and emptied.
