Span saw for cutting firewood. Her arms are not parallel: the blade is longer than the rope. One of the arms protrudes from under the blade and serves as a handle. One arm of some saws has a handle cut out (1).
Today, the ordinary span saw is replaced by a metal arc saw, which is also used for felling small trees.
The firewood to be cut is usually placed on a sawhorse. The saw works in both directions and is held horizontal or at an angle. [MOT]
