This mainly depends on the style of paper cutter you use. Guillotine paper cutters, the type that cut through large stacks of paper, require blade re-sharpening from time to time. We recommend that you still have a replacement blade on hand to prevent any downtime while the dull blade is re-sharpened.
Paper Cutter Blade
Rotary paper cutters often feature self-sharpening blades. However, this style of blade eventually becomes dull and must be changed. Arm style paper cutters may be re-sharpened too, with disposable replacement blades available with some models.
