This is a paper knife with a pad. Because paper cutting knife often scratch the desktop when it works , so this design added a pad structure in the knife head. Pushing pad and blade when using it, inserting paper between pad and blade, cutting pad and blade can move synchronously, can be in any scene to complete the cutting. And this design can switch to the conventional paper cutting knife blade used alone.
