Wedges are two inclined planes that meet at an angle and can be used to hold doors open, split objects in half, or cut and hunt as American Indians did as far back as 8000 BC. Axes, knives, forks, and teeth can all be considered types of wedges, while wedges have been used as tools since ancient times for various purposes like cutting and hunting.
