Knife-Edges
Regardless of the material being slit, score-cut knives should have rounded edges. Experience may show that other combinations of included angles and edge radii may give more satisfactory results on some materials. These illustrations, however, should be used as a guide. The cross-sections show the mean radius of each class of edge magnified approximately 60 times.
