Forged in Fire S04E08 - The Cinquedea

Four bladesmiths are welcomed to the forge with a curveball–they must utilize questionable steel from mining tools to forge a blade in their signature style. Given the option to add high carbon steel to their knives, the smiths make risky decisions to construct a cutting edge tough enough to make it to the next round. Ultimately, two smiths survive to forge an intricately designed and deadly Italian sword–the Cinquedea.
