An axe is a tool for wood. 
People use it to cut trees. They use it to split wood too. 
Long ago, people used stone for the head. Later, they used metal. Some axes were even made of jade.
Some axes are small. You can hold them in one hand. Others are big and heavy.
People use axes for many jobs. They even use them in sports. 
An axe is a tool used to cut wood. 
An axe is a simple machine. It works like a wedge. A wedge is two sloped sides that meet at a point. When the blade hits wood, it pushes the wood apart. The handle also works like a lever. A lever helps you use more force. This makes cutting much easier.
People have used axes for thousands of years. Long ago, people used stone. Some stone axes had no handles. These are called hand axes. Later, people added handles. They used wood, birch-tar, or rawhide to hold the parts together. 
As technology grew, people made axes from copper and bronze. Later, they used iron and steel. 

An axe is a very old tool used to shape or split wood. 

An axe works as a simple machine called a wedge. A wedge is a shape with two sloped sides. When the blade hits the wood, it concentrates pressure at the edge. This pressure helps the blade cut and split the wood into two parts. 
Humans have used axes for millions of years. The very first axes were stone hand axes without handles. These date back as far as 1.5 million years. 

As people learned to work with new metals, axes changed too. They moved from stone to copper and bronze. 
Axes are linked to many parts of human culture. Some axes were used in religious ceremonies, like the double axe in Minoan Crete. 

An axe is a versatile implement used for thousands of years. 

This wedge shape is essential to how the tool works. When the blade strikes wood, it concentrates pressure at the edge. This pressure allows the tool to cut and split wood into two parts. The movement of the head behind the initial cut completes the split. The handle also plays a vital role in the mechanics. It acts as a lever, which allows the user to increase force at the cutting edge. This combination of a wedge and a lever reduces the total effort needed by the user.
Axes are specialized by their blade angle and their specific purpose. Cutting axes, used for felling, limbing, and bucking, have a shallow or acute wedge angle. In contrast, splitting axes have a deeper or more obtuse angle to push wood apart. Many axes are double bevelled, meaning they are symmetrical about the blade axis. However, some specialist broadaxes use a single bevel blade. Other tools include the adze, where the head is perpendicular to the handle. An adze is used to rip a level surface into a horizontal piece of wood.
There are many other specific types of axes used in woodworking. A broadaxe is used for hewing, which is the process of squaring off round timbers. A hatchet is a small, light axe designed for one-handed use during travel. Carpenter's axes are slightly larger and often feature a hammer on the back side, called the poll. Mortising axes are used to create mortises by removing wood between two drilled holes. Some versions, like the twybil, use two blades to separate fibers and lever out waste.
The history of the axe tracks the development of human technology. The earliest axes were stone hand axes used without handles. These date back as far as 1.5 million years. Early examples were found in Southern Ethiopia and the Olduvai Gorge. Later, hafted axes appeared, with Northern Indigenous Australians using them at least 46,000 years ago. As metallurgy advanced, axes were made from copper, bronze, iron, and eventually steel. In the Bronze Age, bronze socketed axes became a primary tool and a store of value.
