S16E6: Surgical Instruments, Ketchup, Double-Decker Buses, Walking Sticks

Medical-grade steel is forged or machined, polished and inspected to create precise surgical instruments. Tomatoes are cooked, strained, seasoned and bottled as ketchup; large chassis and body sections are assembled into double-decker buses; and selected wood is straightened, shaped and finished into walking sticks.
