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. The step is the area of the anvil between the 'horn' and the 'face'.

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

Also, sharp edges tend to cut into the metal being worked and may cause cracks to form in the workpiece. Any marks on the face will be transferred to the work. It is generally made of hardened steel and should be flat and smooth with rounded edges for most work. The primary work surface of the anvil is known as the face.
