我想为独木舟的茎弯曲灰烬。我正在尝试选择直纹四分之一锯片。我应该选择木材生长速度更快或更慢的部件吗？

What is ‘best’? Straightness and freedom from
knots have already been mentioned. Equally, if
not more important is the speed of growth of
the wood. The faster it is grown, the greater the
proportion of summer growth to winter growth.
It is the summer growth that is strong and that
will put up with being bent, while the winter
growth is relatively weak. Wood with say three
growth rings per inch will bend far more
successfully than wood with 10 rings per inch.
