Capable of opening up to 40,000 envelopes per hour, FP LO3060 is incredibly fast and efficient.

This also protects internal contents of envelope that might otherwise accidentally get cut in opening process. depth of cut can be configured as well to 0.0" (not cut, just counting) to .125". letter opener also comes with an optional counter and a variable speed control. It comes with a stand and a waste bin so there is no paper mess left behind.
