This week on Forged in Fire, the masters compete against their own apprentices using the jelly-roll technique.

The task this week is to make a cleaver utilizing the method, which involves taking seven to 13 layers of steel and then flattening them out into a strip.

Red-hot metal rolled up in a 'jelly-roll' — If the metal is tapered before rolling a whirlpool effect can be created

This is later heated up and rolled into a jelly roll shape, before being welded together with pressure.

This results in some stunning patterns on the metal and is a technique often seen in Damascus steel and decorative weapons.
