Stake anvils are very useful in a traditional shop. They are used to bend small coils, fit inside a hollow object, or finish small forgings. They ranged in size from tiny ones used by Jewelers to 20lb. stakes used by smiths to 200lb Bickerns used as an anvil in the shop.
My small stake anvil is forged of wrought iron with a steel face. It has the classic shape with one round horn and one square horn. It is an old one, and has some wear from use. It had been -34F the night before I took this picture. It was still well below freezing in the shop, and the stake anvil is very frosty!
My large stake anvil is from the pre-modern era. The fluted column, shield shaped boss, and combination of round and square horns may place this anvil in the 18th century or earlier. It is wide, long, and tall and weighs around 180lbs.
Stake anvils are still used in the Blacksmith Shop. At the SOFA Quad-State 2013 Conference a team of smiths used a steam hammer to make the one pictured below!
