How It's Made S20 E9
Thinning Shears, Wagon Wheels, Toaster Pastries, Violin Bows

Steel blades are shaped, toothed, hardened and sharpened to produce hair-thinning shears. Wooden hubs, spokes and rim sections are fitted together and reinforced to make wagon wheels; sheets of pastry are filled, sealed, baked and coated to create toaster pastries; and carefully selected wood is shaped, curved and fitted with horsehair to produce violin bows.
