Wedge
A wedge is a tool with a thick back and a thin, sharp edge, like two slopes back to back. Pushing on the back drives the thin edge in, and its sloping sides push things apart with a big force. So a wedge cuts, splits and digs, where a ramp is for moving loads. Knives, axes, chisels, the point of a nail, a pickaxe and our front teeth all work as wedges.
