A steel sword design is an item required to make Steel ceremonial swords in the Artisans Workshop. They require 40 Iron ores and 80 Coal to be made. These ores should then be deposited in the smelter, and smelted to a ingot. This ingot could then be used on the furnaces next to the anvils to get a Steel ingot (heated). This heated ingot could then be used on the anvil, and hammered to the correct shape, to make a Ceremonial sword. Then you should go to Abel and Egil to let them rate the sword. This rating decides how much experience you will get, which is the only reward for this performance.
