Episode overview
Steel rods are cut, hardened and given finely textured surfaces before receiving protective handles to become knife-sharpening steels. Flexible bladders, valves and housings are assembled into pumps used for controlled fluid transfer; perforated metal tops are fitted with padding and folding legs to make ironing boards; and lightweight shafts and blades are shaped into kayak paddles.
