A wedge is a thin piece of metal that is used to create a notch or recess in a surface. It can be used to cut, scrape, and form material. The shape of the wedge determines how it will perform. For example, the shape of the wedge determines how deep it can go into the material before it starts cutting into it.
A wedge is specifically designed to allow a person to insert it into an opening and then push up on it until the object being wedged has been raised out of its original position. Wedges are typically used to raise heavy objects such as concrete slabs or large pieces of metal.
