You can buy bamboo fly rod blanks separately from the hardware and build the rods yourself.
If you are keen to build your own rods but do not want to build the blank, buying a blank to start you off with crafting your own is just the thing.
Alternatively, the supplier may provide additional options such as; provide a blank with ferrules, or the blank with the ferrules already attached etc.
Out of around 1,000 species and 91 genera, Arundinaria amabilis or Pseudosasa amabilis - Tonkin Cane, is the prized species most often used for bamboo fly rod blanks and building rods but Calcutta Cane was also used in this craft.
