For green wood outside, one should always use a coarse-toothed saw. In a saw with fine teeth, the wet sawdust sticks between the teeth and the saw quickly becomes too clogged up to cut. For dry wood a saw with fine teeth is best. Dry soft woods can to some extent be cut with a coarse-toothed saw, but with dry hardwoods and bamboo, a fine-toothed saw is absolutely recommended.
