Some men chop down trees, swinging a sharp ax again and again, chipping away at the trunk until it breaks and the tree comes crashing down. Some use a saw, sometimes a two-man saw, drawing it back and forth, back and forth, slowly grinding into the tree trunk until it is completely severed and topples over.
Most use a motorized saw, tearing voraciously into the tree, motor screaming and fumes spewing.
And then there are some who shred, reducing the tree to fibers.
