The first three are without toothing. The fourth can also handle lower quality cardboard. It is used for the so-called perforation cut. The fifth is also for demanding materials, it penetrates the material better. Knives 4 and 5 cannot be ground! These segmental knives are also supplied with a nose and one-sided or both sides with a closed groove. Normal thicknesses are 6, 8 and 10 mm. We also supply finishing knives and cutting knives. We know this field so well that just the catalog number of the blade is sufficient for us for all known machines to identify it.
