Rotary sawing is a method of cutting logs in which the entire log is placed on a lathe and rotated against a stationary knife. This technique produces a wide sheet of veneer by peeling the log like a tape, rather than cutting it into solid boards or planks. As a result, the output is primarily thin sheets of veneer rather than solid stock lumber.

In contrast, quarter sawing, plain sawing, and rift sawing all involve cutting the log in a way that produces larger, thicker pieces of wood, suitable for use as solid lumber. Each of these methods has its own unique grain pattern and characteristics influenced by the cutting angle and process used. Thus, rotary sawing stands out as the method that does not yield solid stock lumber, focusing instead on veneer production.
