How do you open a can with a can opener?

Answer:
There are many types of can openers.

The general type has a sharp pointed blade which punctures the edge of can and with the rim of the can as lever the blade slowly cuts the circular inner tin as the cutter is slowly lifted at each upward movement of the handle to cut open the can.

The circular disc uses the same technique only the key is rotated with the cutter placed on the rim edge.
