We just learned about the Slack Tub.
Another thing a blacksmith does is called Drawing Down.
If a blacksmith wants to make some metal thinner, they can hit the metal sideways with the peen hammers or fuller that we've learned about and try and keep it the same width but make it longer.
If you think of the metal like clay, and you tried to push the clay out the long way to make it thinner, that is what the blacksmith is doing with the hammer and the metal when they are drawing.
After they have spread it out with the peen hammer or fuller, they use the flat part of the hammer with the anvil to flatten out any bumps they may have made in the metal.
