A Wedge changes an input force by a change when a mechanical advantage increases as it becomes longer and thinner.
That sounds like a 'wedge', like a chisel.
A "regular" can opener is a machine that combines a wedge (to cut through the top of the can) with a wheel and axle (which moves the can opener's cuttng wheel -- the wedge -- around the top of the can). The input force is provided by the operator, either by hand or via electric power. The output force is the separation of the metal of the top and the movement of the opener around the can. We also find that the can and the openers parts get a bit warmer with its use, and there are losses in the system due to friction.
The first class lever (force, fulcrum, load) doesn't change the force if the lever is symetrical. Note that if it is assymetrical, the force will change.
A hanging pulley or a Class-I lever can both do that.

when it changes its direction
Using mechanical advantage to offer a large lifting force from a much smaller input force, essentially an inclined plane or wedge.
First Class Levers The fulcrum is between the input force and the load Always changes the direction of the input force and can be used to increase the force or the distance Second-class levers The load is between the fulcrum and the input force Does not change direction of the input force Output force is greater than the input force. Third-Class lever The input force is between the fulcrum and the load Does not change the direction of the input force Output force is less than input force.

They pulley is applied by the output force and then it is being added on by the input work.

Yes, there is a lever in the flat iron. The fulcrum is where the 2 types of the flat iron come together, and your input force is when you squeeze the 2 parts together to grab your hair.
The relationship between the two is, the bigger the wedge, the less force you need and the smaller the wedge, the more force you need.
