Farmed Caviar, Intake Manifolds, Motorcycle Jackets, Shovels & Spades

How It's Made – Season 18

Farm-raised sturgeon provide roe that is carefully separated, graded and salted to produce caviar. Intake manifolds are cast and machined to distribute air through an engine, protective motorcycle jackets are cut and sewn from leather with reinforced panels, and steel blades are shaped, hardened and fitted to handles to make shovels and spades.
