What is made of wood but can't be sawed?

Sawdust is made of wood and can't be sawed. It is too small to cut and is the remains and the dust of already-cut wood.

Sawdust is also known as wood dust. Sawdust comes in a variety of colors and densities, depending on the wood and the tooth of the saw used. It is a powdery substance created from sawing wood. When overly inhaled, sawdust makes a person gag, cough or sneeze, and breathing it in is bad for one's health. Sawdust is used to make particle board when it comes in bigger chunks. Sawdust is also used in art.
