This paper cutter has been out awhile now, and I have heard rave reviews!  Therefore, I decided to include it on my most recent order to try it out!  Underneath the cutter is a handle for the cutting lever and also an extension for the left side for measuring.  The clear piece you see on the right is to press down and hold your paper in place as you cut.  It cuts precisely and without the fraying we sometimes see with our high quality Whisper White cardstock.  And it can cut just slivers of cardstock with ease.  It is safe and will not cut fingers, as others have attested!  I’ve just cut some scraps so far but I’m anxious to work more with this wonderful tool.
