Powerfibers

Here is a picture of a slice from a bamboo culm I received from a buddy. Check out the dense powerfibers. Powerfibers are located on the outer part of the bamboo giving this living material its unique strength, flexibility and durability. I'm told that this is a slice taken from one of the thinner culms, showing at least 4 mm of powerfibers.

The quality of bamboo rod builders look for making bamboo fly rods are straightness, no (or hardly any) damages by insect bites, watermarks, etc. I'm sure these culms will end up as excellent bamboo fly rods!
