What it is Filled
An anvil is a passive tool with a hard working surface and a supporting body that resists hammer blows while metal or another workpiece is forged, shaped, straightened or otherwise worked.
In scope
- Anvil forms used in forging, forming and related metalworking
- Faces, horns, edges, steps and tool-receiving holes where present
- Body and working-surface construction
- Mass, working dimensions and mounting interfaces
- Condition and suitability for specified tools, workpieces and operations
Out of scope
- Hammers, presses and other tools that supply the working force
- Forges, furnaces and workpiece heating processes
- Removable hardy tools, stakes and other anvil accessories as separate tool kinds
- Stands, foundations and workshop layouts as independently managed objects
- Product lines, individual asset records and ownership histories
- The anatomical incus, anvil clouds and anvils incorporated into measuring instruments
Why it exists Filled
Enable an agent to recognise an anvil, assess its working surfaces and support, and judge its suitability for a proposed metalworking operation.
Distinguishing features Filled
- Its intended working role is to support a workpiece and resist applied metalworking forces rather than deliver the blow.
- Its working surfaces are intended for direct forming contact; a general bench or pedestal primarily supports equipment or materials.
- Identification depends on working role and construction, not a horn-shaped silhouette: hornless anvils remain possible.
- A flat reference surface alone does not establish an anvil; a surface plate is intended for inspection rather than hammer forming.
- Distinguish a standalone anvil from a removable stake or forming insert by whether it provides the principal support body or is tooling carried by another support.
What robots and AI may and may not do Filled
Must not
- Strike or work metal on an anvil while people stand within reach of flying scale or fragments.
- Use an anvil that is cracked, unsecured or mounted at an unsafe height.
- Drop or move a heavy anvil without lifting equipment and a clear area.
- Misrepresent a modern or cast iron anvil as an antique forged one in a sale.
Only with a human decision
- Moving or lifting an anvil where people could be injured if it falls.
May
- Describe anvils, their parts and their safe use in forging from craft sources.
- Inspect an anvil for cracks, chipped edges or loose mounting and report them to its keeper.
Moral aspects Filled
- Smithing is skilled work; injuries from flying metal and heavy loads fall on workers and onlookers.
- Old anvils are heritage objects of local trades and forges.
Who is affected
- Smiths and apprentices
- Onlookers
- Collectors
Owners Filled
Steward
The person or workshop that keeps it.

Open questions
- Does the registry intend only standalone metalworking anvils, or also powered-hammer anvil blocks and other integral reaction supports?
- Where should the catalogue draw the boundary between small anvils, bench blocks and removable forming stakes?
- Which authoritative sources establish construction, hardness and dimensional ranges for the principal anvil forms?
- Which standards or manufacturer criteria apply to tooling fit, mounting, inspection and service withdrawal, and do any certification marks apply?
