An anvil is a metalworking tool consisting of a large block of metal (usually forged or cast steel), with a flattened top surface, upon which another object is struck (or "worked").

Contents

Anvils are massive because the higher their inertia, the more efficiently they cause the energy of striking tools to be transferred to the work piece. In most cases the anvil is used as a forging tool. Before the advent of modern welding technology, it was the primary tool of metal workers. [1]

The great majority of modern anvils are made of cast steel that has been heat treated by either flame or electric induction. Inexpensive anvils have been made of cast iron and low-quality steel, but are considered unsuitable for serious use, as they deform and lack rebound when struck.

The largest single piece tool steel anvil that is heat treated is 1600 pounds. This anvil was made in 2023 by Oak Lawn Blacksmith. There are larger anvils that are made out of multiple pieces such as “The mile long anvil” made by Napier which weights 6500 pounds. This anvil is not heat treated or made from tool steel.

The primary work surface of the anvil is known as the face. It is generally made of hardened steel and should be flat and smooth with rounded edges for most work. Any marks on the face will be transferred to the work. Also, sharp edges tend to cut into the metal being worked and may cause cracks to form in the workpiece. The face is hardened and tempered to resist the blows of the smith's hammer, so the anvil face does not deform under repeated use. A hard anvil face also reduces the amount of force lost in each hammer blow. Hammers, tools, and work pieces of hardened steel should never directly strike the anvil face with full force, as they may damage it; this can result in chipping or deforming of the anvil face.

The horn of the anvil is a conical projection used to form various round shapes and is generally unhardened steel or iron. The horn is used mostly in bending operations. It also is used by some smiths as an aid in "drawing down" stock (making it longer and thinner). Some anvils, mainly European, are made with two horns, one square and one round. Also, some anvils are made with side horns or clips for specialized work.

The step is the area of the anvil between the "horn" and the "face". It is soft and is used for cutting; its purpose is to prevent damaging the steel face of the anvil by conducting such operations there and so as not to damage the cutting edge of the chisel, though many smiths shun this practice as it will damage the anvil over time.

There have also been other additions to the anvil such as an upsetting block; this is used to upset steel, generally in long strips/bars as it is placed between the feet of the anvil. Upsetting is a technique often used by blacksmiths for making the steel workpiece short and thick, having probably been originally long and thin.

The hardy hole is a square hole into which specialized forming and cutting tools, called hardy tools, are placed. It is also used in punching and bending operations. These are not to be confused with swage blocks, although their purpose is similar.

The pritchel hole is a small round hole that is present on most modern anvils. Some anvils have more than one. It is used mostly for punching. At times, smiths will fit a second tool to this hole to allow the smith more flexibility when using more than one anvil tool.

Placement

The anvil is placed as near to the forge as is convenient, generally no more than one step from the forge to prevent heat loss in the work piece. An anvil needs to be placed upon a sturdy base made from an impact and fire resistant material. Common methods of attaching an anvil are spikes, chains, steel or iron straps, clips, bolts where there are holes provided, and cables.

The most common base traditionally was a hard wood log or large timber buried several feet into the floor of the forge shop. In the industrial era, cast iron bases became available. They had the advantage of adding additional weight to the anvil, making it more stable. These bases are highly sought after by collectors today. When concrete became widely available, there was a trend to make steel reinforced anvil bases by some smiths, though this practice has largely been abandoned. In more modern times, anvils have been placed upon bases fabricated from steel, often a short thick section of a large I-beam. In addition, bases have been made from dimensional lumber bolted together to form a large block or steel drums full of oil-saturated sand to provide a damping effect. In recent times, tripod bases of fabricated steel have become popular.

Types

There are many designs for anvils, which are often tailored for a specific purpose or to meet the needs of a particular smith. For example, there were anvils specifically made for farriers, general smiths, cutlers, chain makers, armorers, saw tuners, coach makers, coopers, and many other types of metal workers. Most of these anvil types look similar, but some are radically different. Saw maker anvils, for instance, are generally a large rectangular block of steel that have a harder surface than most other anvils due to hammering on a harder steel for saws. Bladesmith anvils tend to be rectangular with a hardy and pritchel, but no horn. Such designs have originated in diverse geographic locations. Several styles of anvils include, Bavarian, French Pig anvil, Austrian, and Chinese turtle anvil.

The Bavarian style is known for the sloped brow. The brow was first used in medieval times to make armor on the church windows below the brow. Common manufactures include, Söding Halbach and Holthaus. This style of anvil is known not to sway in the face due to the extra mass with the brow.

The common blacksmith's anvil is made of either forged or cast steel, forged wrought iron with a hard steel face or cast iron with a hard steel face. Cast iron anvils are not used for forging as they are incapable of standing up to the impact and will crack and dent. Also, cast iron anvils without a hard steel face do not have the rebound that a harder anvil would and will tire out the smith. Historically, some anvils have been made with a smooth top working face of hardened steel welded to a cast iron or wrought iron body, though this manufacturing method is no longer in use. At one end, the common smith's anvil has a projecting conical bick (beak, horn) used for hammering curved work pieces. The other end is typically called the heel. Occasionally, the other end is also provided with a bick, partly rectangular in section. Most anvils made since the late 18th century also have a hardy hole and a pritchel hole where various tools, such as the anvil-cutter or hot chisel, can be inserted and held by the anvil. Some anvils have several hardy and pritchel holes, to accommodate a wider variety of hardy tools and pritchels. An anvil may also have a softer pad for chisel work.

An anvil for a power hammer is usually supported on a massive anvil block, sometimes weighing over 800 tons for a 12-ton hammer; this again rests on a strong foundation of timber and masonry or concrete.

An anvil may have a marking indicating its weight, manufacturer, or place of origin. American-made anvils were often marked in pounds. European anvils are sometimes marked in kilograms. English anvils were often marked in hundredweight, the marking consisting of three numbers, indicating hundredweight, quarter hundredweight and pounds. For example, a 3-1-5, if such an anvil existed, would be 3×112 lb + 1×28 lb + 5 lb = 369 lb ≈ 168 kg.

Cheap anvils made from inferior steel or cast iron and often sold at retail hardware stores, are considered unsuitable for serious use, and are often derisively referred to as "ASOs", or "anvil shaped objects". [2] Amateur smiths have used lengths of railroad rail, forklift tines, or even simple blocks of steel as makeshift anvils.

A metalworking vise may have a small anvil integrated into its design.

Anvils were first made of stone, then bronze, and later wrought iron. As steel became more readily available, anvils were faced with it. This was done to give the anvil a hard face and to stop the anvil from deforming from impact. Many regional styles of anvils evolved through time from the simple block that was first used by smiths. The majority of anvils found today in the US are based on the London pattern anvil of the mid-19th century.

The wrought iron steel faced anvil was produced up until the early 20th century. Through the 19th and very early 20th centuries, this method of construction evolved to produce extremely high quality anvils. The basic process involved forge-welding billets of wrought iron together to produce the desired shape. The sequence and location of the forge-welds varied between different anvil makers and the kind of anvil being made. At the same time cast iron anvils with steel faces were being made in the United States. At the dawn of the 20th century solid cast steel anvils began to be produced, as well as two piece forged anvils made from closed die forgings. Modern anvils are generally made entirely from steel.

There are many references to anvils in ancient Greek and Egyptian writings, including Homer's works. They have been found at the Calico Early Man Site in North America.

Anvils have since lost their former commonness, along with the smiths who used them. Mechanized production has made cheap and abundant manufactured goods readily available. The one-off handmade products of the blacksmith are less economically viable in the modern world, while in the past they were an absolute necessity. However, anvils are still used by blacksmiths and metal workers of all kinds in producing custom work. They are also essential to the work done by farriers.

Firing

Anvil firing is the practice of firing an anvil into the air using gunpowder. It has been popular in California, the eastern United States and the southern United States, much like how fireworks are used today. There is a growing interest in re-enacting this "ancient tradition" in the US, which has now spread to England. [3]

Television and film

A typical metalworker's anvil, with horn at one end and flat face at the other, is a standard prop for cartoon gags, as the epitome of a heavy and clumsy object that is perfect for dropping onto an antagonist. This visual metaphor is common, for example, in Warner Brothers' Looney Tunes and Merrie Melodies shorts, such as those with Wile E. Coyote and the Road Runner. [4] Anvils in cartoons were also referenced in an episode of Gilmore Girls , where one of the main characters tries to have a conversation about "Where did all the anvils go?", a reference to their falling out of use on a general scale. [5] [6] Animaniacs made frequent gags on the topic throughout its run, even having a kingdom named Anvilania, whose sole national product is anvils. [7]

Books

Dwarves were blacksmiths who used anvils for metalworking on C.S.Lewis's The Chronicles of Narnia , most iconically on The Magician's Nephew and Prince Caspian ; as well as on J.R.R. Tolkien's The Hobbit .

Anvils have been used as percussion instruments in several famous musical compositions, including:

Wagner's Ring des Nibelungen is notable in using the anvil as pitched percussion. The vast majority of extant works use the anvil as unpitched. However tuned anvils are available as musical instruments, albeit unusual. These are not to be confused with the "sawyers' anvils" used to "tune" big circular saw blades. Steel anvils are used for tuning for use as musical instruments, because those based partly on cast iron and similar materials give a duller sound; this is actually valued in industry, as pure steel anvils are troublesomely noisy, though energetically more efficient. The hammer and anvil have enjoyed varying popularity in orchestral roles. Robert Donington pointed out that Sebastian Virdung notes them in his book of 1510, and Martin Agricola includes it in his list of instruments (Musica instrumentalis deudsch, 1529) largely as a compliment to Pythagoras. In pre-modern or modern times anvils occasionally appear in operatic works by Berlioz, Bizet, Gounod, Verdi, and Wagner for example. Commonly pairs of anvils tuned a third apart are used.

In practice modern orchestras commonly substitute a brake drum or other suitable steel structure that is easier to tune than an actual anvil, although a visibly convincing anvil-shaped prop may be shown as desired. In Das Rheingold Wagner scored for nine little, six mid-sized, and three large anvils, but orchestras seldom can afford instrumentation on such a scale. [9]

A forge is a type of hearth used for heating metals, or the workplace (smithy) where such a hearth is located. The forge is used by the smith to heat a piece of metal to a temperature at which it becomes easier to shape by forging, or to the point at which work hardening no longer occurs. The metal is transported to and from the forge using tongs, which are also used to hold the workpiece on the smithy's anvil while the smith works it with a hammer. Sometimes, such as when hardening steel or cooling the work so that it may be handled with bare hands, the workpiece is transported to the slack tub, which rapidly cools the workpiece in a large body of water. However, depending on the metal type, it may require an oil quench or a salt brine instead; many metals require more than plain water hardening. The slack tub also provides water to control the fire in the forge.

<span class="mw-page-title-main">Wrought iron</span> Iron alloy with a very low carbon content

Wrought iron is an iron alloy with a very low carbon content in contrast to that of cast iron. It is a semi-fused mass of iron with fibrous slag inclusions, which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welded, but is more difficult to weld electrically.

<span class="mw-page-title-main">Blacksmith</span> Person who creates wrought iron or steel products by forging, hammering, bending, and cutting

A blacksmith is a metalsmith who creates objects primarily from wrought iron or steel, but sometimes from other metals, by forging the metal, using tools to hammer, bend, and cut. Blacksmiths produce objects such as gates, grilles, railings, light fixtures, furniture, sculpture, tools, agricultural implements, decorative and religious items, cooking utensils, and weapons. There was an historical distinction between the heavy work of the blacksmith and the more delicate operation of a whitesmith, who usually worked in gold, silver, pewter, or the finishing steps of fine steel. The place where a blacksmith works is called variously a smithy, a forge or a blacksmith's shop.

<span class="mw-page-title-main">Forging</span> Metalworking process

Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer or a die. Forging is often classified according to the temperature at which it is performed: cold forging, warm forging, or hot forging. For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons. Forging has been done by smiths for millennia; the traditional products were kitchenware, hardware, hand tools, edged weapons, cymbals, and jewellery.

<span class="mw-page-title-main">Metalworking</span> Process of making items from metal

Metalworking is the process of shaping and reshaping metals to create useful objects, parts, assemblies, and large scale structures. As a term it covers a wide and diverse range of processes, skills, and tools for producing objects on every scale: from huge ships, buildings, and bridges down to precise engine parts and delicate jewelry.

<span class="mw-page-title-main">Repoussé and chasing</span> Metalworking technique

Repoussé or repoussage ( ) is a metalworking technique in which a malleable metal is shaped by hammering from the reverse side to create a design in low relief. Chasing or embossing is a similar technique in which the piece is hammered on the front side, sinking the metal. The two techniques are often used in conjunction.

Forge welding (FOW), also called fire welding, is a solid-state welding process that joins two pieces of metal by heating them to a high temperature and then hammering them together. It may also consist of heating and forcing the metals together with presses or other means, creating enough pressure to cause plastic deformation at the weld surfaces. The process, although challenging, has been a method of joining metals used since ancient times and is a staple of traditional blacksmithing. Forge welding is versatile, being able to join a host of similar and dissimilar metals. With the invention of electrical welding and gas welding methods during the Industrial Revolution, manual forge-welding has been largely replaced, although automated forge-welding is a common manufacturing process.

A ball-peen or ball peinhammer, also known as a machinist's hammer, is a type of peening hammer used in metalworking. It has two heads, one flat and the other, called the peen, rounded. It is distinguished from a cross-peen hammer, diagonal-peen hammer, point-peen hammer, or chisel-peen hammer by having a hemispherical peen.

A bloomery is a type of metallurgical furnace once used widely for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom. The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into wrought iron. Blast furnaces, which produce pig iron, have largely superseded bloomeries.

Hardy tools, also known as anvil tools or bottom tools, are metalworking tools used in anvils.

A pritchel is a type of punch used in forging, particularly in making nail holes in horseshoes. The horseshoe is heated and a hole is punched through 90 percent of the steel with a forepunch or drift punch. The pointed end of the tool should be kept sharp so that the burr is cut out smoothly. The punched hole is lined up over the pritchel hole and the pritchel is driven into the hole, knocking out the remaining metal at the bottom of the punched hole. The temperature of the pritchel should be always be below the red-hot stage as the tool itself will bend and lose the temper. When over-heated it is advised to cool it in water immediately.

Sword making, historically, has been the work of specialized smiths or metalworkers called bladesmiths or swordsmiths. Swords have been made of different materials over the centuries, with a variety of tools and techniques. While there are many criteria for evaluating a sword, generally the four key criteria are hardness, strength, flexibility and balance. Early swords were made of copper, which bends easily. Bronze swords were stronger; by varying the amount of tin in the alloy, a smith could make various parts of the sword harder or tougher to suit the demands of combat service. The Roman gladius was an early example of swords forged from blooms of steel.

Ironwork is any weapon, artwork, utensil, or architectural feature made of iron, especially one used for decoration. There are two main types of ironwork: wrought iron and cast iron. While the use of iron dates as far back as 4000 BC, it was the Hittites who first knew how to extract it and develop weapons. Use of iron was mainly utilitarian until the Middle Ages; it became widely used for decoration in the period between the 16th and 19th century.

<span class="mw-page-title-main">Fuller (metalworking)</span>

In metalworking, a fuller is a tool used to form metal when hot. The fuller has a rounded, either cylindrical or parabolic, nose, and may either have a handle or a shank. The shank of the lower fuller allows the fuller to be inserted into the hardy hole of the anvil. Upper fullers furthermore come in "straight" or "cross" varieties, depending on the orientation of the handle relative to the face.

<span class="mw-page-title-main">Bladesmith</span> Person who uses an anvil and forge to make various types of blades

Bladesmithing is the art of making knives, swords, daggers and other blades using a forge, hammer, anvil, and other smithing tools. Bladesmiths employ a variety of metalworking techniques similar to those used by blacksmiths, as well as woodworking for knife and sword handles, and often leatherworking for sheaths. Bladesmithing is an art that is thousands of years old and found in cultures as diverse as China, Japan, India, Germany, Korea, the Middle East, Spain and the British Isles. As with any art shrouded in history, there are myths and misconceptions about the process. While traditionally bladesmithing referred to the manufacture of any blade by any means, the majority of contemporary craftsmen referred to as bladesmiths are those who primarily manufacture blades by means of using a forge to shape the blade as opposed to knifemakers who form blades by use of the stock removal method, although there is some overlap between both crafts.

<span class="mw-page-title-main">Saint Clement's Day</span>

Saint Clement's Day was traditionally, and in some places still is, celebrated on 23 November, a festival between Halloween and Christmas. Pope Clement I is the patron saint of metalworkers and blacksmiths, and so these workers traditionally enjoyed a holiday on his feast day.

Makera Assada is among the areas that form the town of Sokoto state of Nigeria. The area is part of Magajin Gari Ward in the southern part of Sokoto North local government area of Sokoto state, bordered Gidan Haki in the east, Digyar Agyare in the west, Mafara in the north and Helele in the south.

Rule based DFM analysis for forging is the controlled deformation of metal into a specific shape by compressive forces. The forging process goes back to 8000 B.C. and evolved from the manual art of simple blacksmithing. Then as now, a series of compressive hammer blows performs the shaping or forging of the part. Modern forging uses machine driven impact hammers or presses that deforms the work-piece by controlled pressure.
