An anvil is a massive metalworking tool used to shape various objects.

It consists of a large block of metal, typically made from forged or cast steel. The primary purpose of an anvil is to serve as a surface for forging. Before modern welding technology was invented, it was the most important tool for metal workers. Anvils must be heavy to work effectively. This mass provides high inertia, which helps transfer the energy from a striking tool directly into the workpiece.

The anvil is composed of several distinct parts designed for specific tasks. The primary work surface is called the face. This area is usually made of hardened steel to ensure it remains flat and smooth. A smooth face is vital because any marks on it will transfer to the metal being worked. The face is also tempered to resist deformation from repeated hammer blows. One end of the anvil features a conical projection known as the horn or bick.

This part is used for bending metal into round shapes or for drawing down stock. Between the face and the horn lies the step. The step is a softer area used for cutting to protect the hardened steel face.

Many anvils include specialized holes to hold different tools. The hardy hole is a square opening used for inserting hardy tools. These tools are used for specialized forming and cutting operations. There is also a pritchel hole, which is a small round hole found on most modern models. This hole is primarily used for punching holes in metal. Some smiths may even use a second tool in the pritchel hole to increase their flexibility. Additionally, some anvils include an upsetting block placed between the feet. This is used for upsetting, a technique that makes a metal workpiece short and thick.

To work properly, an anvil must be placed on a very stable base. It is usually positioned near a forge, often no more than one step away. This proximity prevents the workpiece from losing too much heat during the forging process. Traditional bases often consisted of a large hardwood log buried deep in the forge floor.

During the industrial era, cast-iron bases became popular because they added extra weight and stability. Some smiths later used steel-reinforced concrete, though this has mostly been abandoned. Modern blacksmiths might use steel I-beams, large wooden blocks, or even steel drums filled with oil-saturated sand to provide a damping effect.

Anvils have evolved significantly through human history. The earliest anvils were made of stone, followed by bronze and later wrought iron. As steel became more available, smiths began facing anvils with it to prevent deformation. In the mid-19th century, the London pattern anvil became a standard design. Most anvils found in the United States today are based on this specific pattern. By the dawn of the 20th century, manufacturers began producing solid cast-steel anvils.

While mechanized production has made many handmade goods less common, anvils remain essential for custom blacksmithing and farrier work.

There are many different types of anvils tailored to specific professions. For example, farriers use specialized designs, as do armorers, cutlers, and saw tuners. Saw maker anvils are often large rectangular blocks with extra-hard surfaces. Bladesmith anvils are typically rectangular and include a horn-less design with a hardy and pritchel. Different regions have also produced unique styles. These include the Bavarian style, which features a sloped brow to prevent swaying. Other historical styles include the French Pig anvil, the Austrian style, and the Chinese turtle anvil.

Anvils vary greatly in size and weight depending on their construction. The largest single-piece tool steel anvil weighs 1,600 pounds (726 kg) and was made in 2023. Some multi-piece anvils are much larger, such as the 6,500-pound (2,948 kg) "mile long anvil" made by Napier. In heavy industrial settings, an anvil for a power hammer might be supported by a block weighing over 800 tons.

Because of their weight, anvils are often marked with their mass. American anvils often use pounds, while European ones use kilograms. English anvils traditionally used a system of hundredweights, quarters, and pounds to indicate their weight.
