Arrow Top and Bottom Knives

Score slitter blades are specially designed knives used to create precise depth grooves and cuts without penetrating completely through the material. These circular blades are essential tools in many industries, from paper to plastic manufacture. Score slitter blades are used to create creases or perforations in various materials, allowing for easy folding, tearing, or breaking along the designated line.

Score slitter blades or “crush cut blades” are used in a cutting process of passing a material between a blade and a hardened roll or “sleeve”. The material is crushed into two separate pieces between the knife and the roll. Because of the constant metal on metal contact between the score cut blade and the roll, these blades don’t have a razor sharp edge, but instead have a rounded edge with a larger radius. This ensures longer run times, as sharper blades would dull quickly and create an uneven cut. A score cut knife is used for continuous cutting applications and is ideal for perforating paper or similar material.
