What is an anvil?
A heavy object of durable material that resists the inertia of a hammer or mechanical ram while supporting material struck by the moving part. The earliest anvil was a heavy stone used to resist the movement of an object struck against it or struck while supported on it. This is such a basic tool that both birds and monkeys have been observed using a stone as an anvil and probably predated man's use of tools. This would make the anvil the FIRST tool.#N#The modern blacksmith's anvil is a sophisticated tool developed over millennia of tool making. Like many iron age tools it has roots in the bronze age. The modern blacksmith's anvil has a hard heat treated tool steel face and a durable soft iron or steel body. The shape and size varies with purpose and regional stylistic preferences. The average blacksmith's anvil weighs 120 pounds (55kg). Universally most anvils have a flat horizontal face and a conical horn or "beak", but there are also hornless styles such as the sawyers anvil. Most anvils have a round punching hole and all modern smithing anvils have a square tooling hole called a hardy or hardie hole.#N#Other anvil features are less standardized such as:#N#Square sectioned pyramidal horn of the European or Leige's pattern.#N#Step and cutting table of the English and American pattern#N#Extra punching holes graduated in size (Hofi and Euroanvil).#N#Carriage maker's side table.#N#Sloped off-hand side of the old central European anvils#N#Upsetting block#N#Turning lugs or cams (farrier's only)#N#"Clip" horns (sharp edged bulges on the horn - farrier's only)#N#Chainmaker's "Dolly" holes (1 or 2, square through side of body)#N#Knifemakers dovetail and plain tooling slots.#N#See Selecting an Anvil .

Softening of metal at room temperature by heat treatment to modify the crystal structure. Ferrous metals (steel and steel alloys) are annealed by heating to just above nonmagnetic or the A3 point then cooled slowly (sometimes as slow as 20°/hour). Non-ferrous, (brass, bronze, copper, silver) are heated to a dull red or just below their melting point and then cooled quickly. Ferrous metals are annealed for machinability and workability. Non-ferrous are annealed to remove work hardening for workability (bending, shaping) and to prevent cracking while working.

Overview
Cutting processes
Cutting is a collection of processes wherein material is brought to a specified geometry by removing excess material using various kinds of tooling to leave a finished part that meets specifications. The net result of cutting is two products, the waste or excess material, and the finished part. In woodworking, the waste would be sawdust and excess wood. In cutting metals the waste is chips or swarf and …
Prehistory
The oldest archaeological evidence of copper mining and working was the discovery of a copper pendant in northern Iraq from 8,700 BCE. The earliest substantiated and dated evidence of metalworking in the Americas was the processing of copper in Wisconsin, near Lake Michigan. Copper was hammered until it became brittle, then heated so it could be worked further. In America, this technology is dated to about 4000–5000 BCE. The oldest gold artifacts in the world …

In some cases rules for ownership, distribution, and trade were created, enforced, and agreed upon by the respective peoples. By the above periods metalworkers w…
General processes
Metalworking generally is divided into three categories: forming, cutting, and joining. Most metal cutting is done by high speed steel tools or carbide tools. Each of these categories contains various processes.
Prior to most operations, the metal must be marked out and/or measured, depending on the desired finished product.
Casting
Casting achieves a specific form by pouring molten metal into a mold and allowing it to cool, with no mechanical force. Forms of casting include:
• Investment casting (called lost wax casting in art)
• Centrifugal casting
• Die casting
Forming processes
These forming processes modify metal or workpiece by deforming the object, that is, without removing any material. Forming is done with a system of mechanical forces and, especially for bulk metal forming, with heat.
Plastic deformation involves using heat or pressure to make a workpiece more conductive to mechanical force. Historically, this and casting were done by bla…
Joining processes
Welding is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material that cools to become a strong joint, but sometimes pressure is used in conjunction with heat, or by itself, to produce the weld.
