Another major component to your blacksmith supplies is an anvil stand. It is vital that you place an anvil on a stand that is the correct height. If the anvil is not at the correct height, the faster you will become fatigued when hammering metal into shape. The height of the anvil stand is different for every blacksmith. Many blacksmiths use the knuckle rule which means that when the anvil is placed on the anvil stand it will reach your knuckles when you loosely ball your fists with your arms at your side. This usually enables a blacksmith to get maximum swing and velocity of the hammer without straining your back. Of course the knuckle technique is no magic bullet and you should adjust the height of the anvil stand to fit your body and needs.
Blacksmiths use various materials to make an anvil stand or you could just buy a stand. Some anvil stands are just a big piece of oak from a fallen tree or if you are in your backyard you can cut down a tree and place the anvil on the stump. Whatever type of anvil stand you use, it must be secure and level. If the stand is not sturdy enough it will just bounce around all over your blacksmith shop. The anvil stand must also be able to secure the anvil from moving around when hammering. If the anvil stand or the anvil itself moves around when you are hammering you will lose efficiency and it will take more time and energy to create the metalwork.
