Leather Briefcases, Crop Dusters, Corn Whiskey, Drag Racing Clutches

How It's Made – Season 15

Bridle leather is cut, reinforced, hand-stitched and fitted with polished hardware to create traditional briefcases. Welded airframes, chemical hoppers and spray systems are assembled into crop-dusting aircraft; ground corn is fermented and distilled into whiskey; and machined plates, friction discs, springs and levers become drag-racing clutches.
