How did medieval blacksmiths make anvils?

Medieval blacksmiths typically did not make anvils themselves; instead, they were often imported or purchased from specialized forges. However, if a blacksmith were to create an anvil, they would start with a large block of iron or steel, heating it in a forge and then hammering it into shape. Anvils were designed with a flat surface for striking, a horn for shaping metal, and a hardy hole for inserting tools. The process required considerable skill and experience to ensure durability and functionality.
