Razor Slitting; Four Factors to Consider
It may be the simplest and cheapest method available, but razor slitting still requires close attention to blade life, edge quality and operator safety.

The three most common methods of slitting flexible web materials are shear, crush (score), and razor. Of these three, razor has the lowest installed cost, being the simplest and cheapest method. It can be easily adapted to almost any machine, in almost any location. It is potentially the cleanest method of slitting, assuming the appropriate materials are being slit.
