How do you make the perfect steel knife? Brian heads to Japan to visit descendants of Samurai sword masters, while back home, Lou reveals the molecular properties of steel. Then Brian and Lou land at the John Deere factory, where they assemble a complex, highly-engineered cutting machine—the lawn mower. Finally, the duo travels to the country's oldest chocolate factory in San Francisco to find out how a bitter bean becomes a scrumptious treat.
