They are not made of metal, wood, or plastic. What they are made of
is a Carbon Fiber Composite - the same material used in the new
Boeing 787 Dreamliner and the Blackbird Stealth Jet as well as
sporting goods that demand strength in a lightweight material.
Carbon fiber is strong like metal, but does not bend, warm like
wood, but does not break.
