Reverse Engineering: Mechanicnal Product - Functional Analysis

1. The primary purpose of the item is to cut things.
2. My educated guess on how scissors work is that the blades slice the paper or whatever material you're cutting. The handles and blades simultaneously move apart and together make a cutting motion every time they are closed.
3. The system inputs are the scissors and the material you're cutting. The intended product function is to cut things. The outputs would be the cut up material. I couldn't get the picture to post.
4. The blades, nut, and handle are visible.
5. I can identify everything going on because all components are visible.
