Description(English)
When we use a paper cutter without a pad it is easy to scratch the plane. Therefore, we design a new paper cutter which cannot scratch the surface. Ordinary paper cutters will scratch the desktop when in use, and we have added pads to the blades. When in use, we push out pads and blades. When we insert paper, we can cut in any scene and the pads and blades can move synchronously. What’s more,this design can switch back to the state where the blade is used independently.
