to remember how much densities can vary.AcaciaAcacia0.66Over 1000

: Pseudosasa japonica for arrows, Phyllostachys bambusoides for
Korean bows. Tonkin cane (Arundinaria amabilis or Pseudosasa
amabilis) also works.0.50-0.85Many varieties. Takes more set per
mass than any hardwood. Can heat treat. Use outer surface as belly.
Bamboo fibers tend to split and pull out when being cross-cut; use
masking tape over the cut line to prevent this.BasswoodTilia
