Consistent repeatability is a critical goal in slitting. However, if slitting is approached as a work of art, where uniqueness is valued, such repeatability will be extremely labor-intensive, if not impossible. Instead, slitting should be a product of science, where the value is in understanding the parameters and being able to replicate the results again and again. Variability and uniqueness in the final product is not valued in science and shouldn’t be valued in the world of slitting. Knifeholders offer direct control over six critical factors—blade sharpness/profile, cant angle, overlap, side load force, overspeed, and slitter geometry—limiting variation and improving slit edge quality in
