Are scissors a wedge?

How can a wedge make work easier?
A wedge makes work easier by increasing the force applied to the object, although it applies the force over a shorter distance. This gives the wedge a mechanical advantage greater than 1.
Why is a chisel a wedge?
It changes the direction of a downward force to a sideways force. As the hammer hits the wedge the downward force is changed to a sideways force pushing the object that the wedge is embedded into sideways. The chisel is a wedge that primarily is used to concentrate the force of a hammer.

What are some examples of Class 2 levers?
In a Class Two Lever, the Load is between the Force and the Fulcrum. The closer the Load is to the Fulcrum, the easier the load is to lift. Examples include wheelbarrows, staplers, bottle openers, nut cracker, and nail clippers. A great example of a Class Two Lever is a wheelbarrow.
