I use the cutter usually tailor to prints on paper, cardboard or foil. By sharp blades works very well. If a blade is a little longer in use and begins to, I exchange this simply with the enclosed spare blades. I use the set for many years and am very satisfied. The cutter is also suitable for coarser tasks, so I have therefore already rumgeschnitzt of cable channels, cable stripped laminate adjusted (when it was okay not exactly), tailored Schalldämmatten for PCs (foam bitumen plate), etc.
