Forged in Fire

In this special kung fu competition, four bladesmiths square off in the Forged in Fire dojo where they must make a matching set of three kunai throwing knives. Only true smithing masters will be able to create three completely identical knives in a short three hours. Each smith has their own strategy of attack, but only two make it through and head back to their home forges, where they are tasked to recreate the legendary 9-Ringed Broadsword. Which smith has the chops to defeat the competition, earning the title Forged in Fire Champion, and a check for $10,000?
