Teeth of the Tegha - S8.E8

Four bladesmiths get revved up when they are tasked with forging signature blades from a burnt up car. With no usable leaf spring, the smiths race to salvage the best steel to make their blades. After a couple rounds of burning rubber, two are sent home to recreate the Serrated Tegha Sword. Which smith will produce a show-stopping weapon worthy of the title of Forged in Fire champion and a check for $10,000?
