Does a can opener make work easier by increasing force, increasing distance, or changing direction?

A can opener makes work easier by increasing force.

Explanation

Technically a can opener is a simple lever that increases the force with which we remove the cap of the can. Levers are rod shaped objects with fulcrum at one end and the length of the lever has a positive impact on the force.

considering the equation

work=force*distance

indicates that increasing the length of the lever/can opener increases the work done by it.
