The 'saw lumber' skill allows you to divide pieces of gathered wood into smaller pieces or shorten.
You can reduce the length of a piece of wood with 'woodcraft whittle'. This lessens the weight by 1 pound by reducing the length. The amount of length removed depends on how long the piece is compared to how heavy it is (i.e. a long lightweight branch will be reduced in length a greater amount than a thick, heavy log).
Pieces of wood larger than 10 inches and heavier than 4 pounds can be split into four equal pieces with the 'woodcraft quarter' command. This is especially useful for crafting smaller pieces such as arrows, though some of the total mass is lost each time it is quartered. Pieces of wood longer than 24 inches can be sawed in half with the woodcraft halve' command.
You can also break down larger containers made from wood into useable lumber. You must be able to pick the container up, and it cannot be too small or too large.
Wood that has been divided in this manner will no longer decay and vanish over time.
