I am presenting New Paper Cutting Knife which takes place on your Desk top. It is made of plastic. Edge of the knife is made sharp enough to cut the corners of the paper pack and sealed covers and strong enough to takeout the staple. Twist on the knife always keeps handle at certain height  which help you to handle the knife. Edges of the handle are rounded to get better grip.  

   It can be modeled in glass and full transparent.
