A Blockhead can wear a tin chest plate by dragging the item into the Blockhead's clothing slot for shirts. The Blockhead then takes a slightly reduced amount of damage. Tin chest plates will wear out naturally, but wear out even faster when the wearer is taking damage from creatures or other players. The tin chest plate is the most protective piece of tin armor that you can craft.
Tin chest plate resembles an iron chest plate, but has a slight blue tint. It also resembles a leather jacket a bit more loosely, but is metallic and tinted blue instead of brown, or any dyed colors of the jacket. The tin chest plate has long sleeves.
