Forged in Fire: Season 4, Episode 4

4 - 4: Makraka

Four bladesmiths face a new twist in the first round when they learn they can't forge any blade in their own style, they must forge a karambit, a curved knife that resembles a claw. The smiths spring into action and uncoil their finest weapon-making skills to forge a unique blade that's fit and formed to withstand brutal testing. The final two competitors have five days to forge one of the deadliest weapons in African history–the Makraka.
