Forged in Fire S08E09 - Headhunters Revenge

Four smiths get to choose their forging method and materials. But there's a catch. Each technique comes with its own clock for the round. Will the smiths opt for the most difficult canister damascus and the four hour clock? Or the easiest ball bearing with only one hour? After a brutal round of testing, the two surviving smiths are tasked with creating the Headhunter Axe in only 3 days. Which smith will stand the test of time to become Forged in Fire Champion and win the $10,000 prize?
