To make an ordinary anvil, four rectangular parallelepipeds are forged together, first in pairs and then all together. The whole constitutes the body of the anvil. The blacksmith adds the feet and the chest or stomach of the anvil then the two horns, one round and one square. A skilled blacksmith forges his own tools like pliers of various sizes or hammers with more or less long wooden handles. The anvil of the blacksmith of the Guédelon medieval construction site in the Yonne department dates from the 15th century and consists of nine blocks welded together.
